MegaFlashROM SCC+ SD

like +10000000!!!

Woow. This is almost cover all possible options for a flash device.

Need it... Oei: Count me in

Another question....
Will it need to be used on an MSX with a DiskDrive? or DiskROM? or does it have the DiskRom/Daisk Basic built in?

@Guillian:

How many mapper pages used on MSX2 with Nextor?

Sweet!!

ehmm
Question
since some computers have an issue with the balance of SCC and PSG
is there some volume setting for the SCC which can be adjusted according to your own needs?

The ULTIMATE cartridge for me personally would have been this one + memory mapper combined, so I can put this in slot 1 and philips music module in slot 2.

But ofcourse what am I complaining? This is very good, and I am probably gonna order this.

Wow, great development. Would save me quite some cartridge switching. And again better than the previous flash cartridge. What next could be added/ improved? I hope we can order soon.
(Could you integrate more soundchips? )

With normal use, I doubt we'll live long enough to find out

@OeiOeiVogeltje: There are not volume setting. You can clone internal PSG using the external one, or patch Konami ROMs to use the external PSG.

@Bastiaan: There is no room in the FPGA for more sound chips.

@yzi: Each sector should last a minimun of 100.000 erase/write cycles. That's about 55 years rewriting your cartridge 5 times per day.

@Creepy: You can load and run up to 9 DSKs in read only mode (swapping disk is possible). To save data game you need to use a disk drive. The next version of Nextor will support DSKs, so it will be possible to save to DSKs in the SD card.

Allow me to clarify on this point since it seems that there is a bit of confussion:

Nextor is a fork of MSX-DOS 2.31

or, put it another way:

Nextor is the next version of MSX-DOS, but unofficial.

So, yes, Nextor is actually MSX-DOS 2, fully compatible with version 2.31 but with more features.

Read this (old) forum topic for more details: Nextor: the whole story

Yes, MSX1 is supported. But unless you have a memory expansion in another slot, you are limited to MSX-DOS 1 mode. And another clarification in case that this is confusing too: "Nextor in MSX-DOS 1 mode" means "MSX-DOS 1 with support for partition management", and nothing else; do not expect FAT16 or any other Nextor features in MSX-DOS 1 mode.

You don't need an internal disk drive to use this toy. But even more, yo don't need a disk drive even for upgrading the Nextor kernel: thanks to the recovery mode, you can upgrade it directly from a SD card!

The same as MSX-DOS 2.31: two pages, that is, 32K.

Well, nobody said "I don't think Linux is the most descriptive name for Minix+" twenty years ago :P

I'm sorry but I can't name it "MSX-DOS" since it is unofficial. I had to choose a new name, and since any name would have been confusing anyway, I just let my ego do the work. :)

Agreed, but add USB and Ethernet ports too for me! ;)

Everything that works in MSX-DOS 2.31 should work in Nextor. And if something does not, I really would like to know!

Wow, nice update to the MegaFlashRom SCC+ Manuel! I may just need to save up for one of these! : )

Had a few questions that I was hoping to get some more clarity on:

1. After flashing a rom, what would be the normal process for launching Nextor again to flash a different rom? I guess I'm just confused, because with MegaFlashRom SCC+ the rom stays into memory until I run OPFX again from MSX-Dos.

2. You mentioned that this allows for use of loading disk images and also swapping between disk images in read only mode. Just wanted to know if it would be as quick and easy as what you demo'd when you launched Solid Snake by highlighting it and hitting enter. Could you describe this process for how this would work? This has been something I've always wanted...

3. Would there still be compatibility issues with certain dsk files or would the majority of .dsk files be able to be read without issue. With some disk emulation programs it seems that some disk files will work and other won't through trial and error.

4. Great! So if Nextor offers support for saving on virtual dsk files, there would eventually be a patch to upgrade the firmware / Nextor being used from the MegaFlashRom SCC+ SD right?

Awesome news, can't wait to try this out. : )

-Thomas

You have two options:

1. Press ESC while booting to prevent the flashed ROM to start (this key is configurable), then use the OPFX tool to erase the ROM.

2. Press cursor up while booting to enter recovery mode, then press F1 to erase the ROM, then reset.

When a new version of Nextor is available, all that Manuel has to do to make a new BIOS is to run the MKNEXROM utility to cook the Nextor kernel base file and his SD driver together. So new BIOS releases will be available at the same time as new Nextor releases.

Would you mind testing Akin? It uses a combo of normal files (to boot) and direct sector reading. I haven't found a tool that emulates both so for me Akin is only playable using a real disk.

Akin works also with RMSX.

Akiguchi: I meant that I cannot run Akin on a real MSX using a disk image or running it directly from SD/CF. I need to write the image to a real disk to be able to run Akin a.t.m.

Duh. Afcourse it works. I meant Magnar, not Akin. Must be the mondays......

Cool! Got to have one!

Guillian is my "MSX Hero"!!!

Where do you live Luppie and how much would I save on shipping compared to a single order? since I would need to travel to your place to pick it up i may end up paying more I live in purmerend.

I have ordered 2 cartridges from the cartridgeshop in the past.
Registered shipping 2 years ago was 24,-

Registered shipping in Nederland is 6,75 so you can do the math.
I was also contacted by an other user to do a combined order and I let him order mine, so I won't be ordering my self anymore.

Count me in, I live in Amsterdam btw

/me wants one :-)

Whoot! Signing up for this one!

Hello pieps
i am going to do a "inkoopactie" for the dutch
whoever wants it
the idea is like this;
We wait for the definite price of the Flashroms (lets say is 100 euro's)
Shipping inside The Netherlands is 6,75 EURO (i think i have nice boxes so the cartbox wont be damaged)
one time shipping from spain divided between the number of participants
Luppie just said it was 24 euro's so lets take that for EXAMPLE
international bankingtransfer also costs money (not much though) lets say 5 euros

i already have 5 people
24 divided by 5 is about 5 euros
5 euros divided by 5 is 1 euro

so
100 + 6,75 + 5 + 1 euros will get you a flashcart

The participants will have the money on my account within 2(?) weeks after i actually start the "inkoopactie"

Participants will also agree that IF i get a Douane import fee to pay (which is not likely to happen)this will also be divided by the participants

this is just a rough idea on how i want to do things

i also dont want more than 20 of these things to handle (its just a hobby )
so first 20 will be served

hang on for an hour or so
then ill have more info

So we fill in the form after we know the price or can we start filling them out now?

Sorry for being a bit confused.

The aiming price is around € 100,-. But even if it turns out € 20,- more, I bet that wouldn't hurt an awful lot for most of us, considering what you get for it. I filled in the form right away... Don't wanna be the unlucky #21

I stole the image oO
But I also backlinked to this article after you filled in the form :D

nope
you are in

more people have ordered already
seems they dont care how much it costs

I'm old fashioned and don't have paypal (well, I forgot my password after using it once some five years ago, but don't tell anyone)... I like to not have to use paypal... So I like this...

Jorito
The calculation was just an EXAMPLE
right prices will be anounced by the time stuff gets done

i have 10 people now who want one
of course people who meet me at the monthly Marienberg MSX clubday will save the 6,75 EURO for dutch shipping of course.
Reden te meer om tegen die tijd eens langs te komen

who knows....

kijk dan man!!!
goed bezig!!

is it still possible to use this device in a slot expander ? Using only the hardisk function ?

11 people

hmmm.. i like the device! .. but to bad it can not work in a slot expander. Most of the time i use my playsoniq also.
This one must be (also) connected in a primary slot. (i use it as a memory expansion) This means for me that i have only one primairy slot left for the rest, like the CF interface and the moonsound or GFX9000. This means that i cannot run Symbos with a MP3 player and using the memory expansion from the playsoniq and the GFX9000....

hmmmm.. have to think .. maybe it's possible to insert the playsoniq as a memory extention only in a subslot
To bad the device cannot run only as a harddrive and disable the other functions when inserting in a sob-slot... hmmm..
Anyway .. the device seems to be cool ... have to think about it.

Just to be clear and to prevent disapointments.
People who replyed to me in this topic "Count me in" and did not register on http://www.msxinfo.net/inkoop-aktie/ do NOT participate in the "Inkoop Aktie"
Please DO fill in the form :D

Just awesome

One question Guillian or if anyone else knows. What exact type of micro SD card needs to be inserted? There are like 10 different types.

But you forgot to make a working link to the picture

I read this in the manual:

is this an error (since you mentioned no more subslot emulation)?

Anyway thanks for the updated info. Now I have to decide if I need 1 or 2 cardslots

No, it is not an error (well, it should be OPFXSD not OPFX)
With that option you can "fake" a Konami cartridge combination. But is not a "real" cartridge combination, like with subslots. This means that if the Konami game only checks an RC number to put some extra features, it will work. But if the cartridge needs code or data from the other cartridge (i.e.: Mission X in Salamander + Nemesis 2) it will not work

13

Updated the order form with the correct shipping cost and the possibility to pick-up your cartridge to save on the shipping cost. If you pick it up, you'll only pay € 1,10 shipping (if we have 20 orders).

Nextor only assings two units per interface at boot time. So if you have a MegaFlashROM SCC+ SD and a floppy in your computer, you drives will be:
MegaFlashROM SCC+ SD = A: and B:
Floppy = C: and D:
Then you can mount more SD units in E:, F:,G: and H:
Also, you can overlap C: and D: floppy units with SD units

No. You can use FAT16 cards for moving files from/to a PC.

Wil long file names also work?

As I've understood a future update will be able to work with concatted DSKs with a built in user disk... But I might have understood it the wrong way... Please confirm...

Seems like it almost a good idea to start a new MSX Club Zuid Holland (yes, I also live kind of close by)

Me to

Hi,

I have a simple question, does it work fine on ST TurboR?

what I mean is that LPE from Padial has a bit problem with this model of TR and it doesn't sometimes start working because of low level of output energy in the ST TurboR. So, What about this Megaflash+SD?

thanks

Hi Guillian!
This seems to me the "definitive" storage solution for any MSX, an excellent hardware with an excellent software support by Nextor.

I also have a few questions, both on hardware and software side:
1) are there compatibility problems with 1chipMSX?
2) how does Nextor assing units name on 1chipMSX with MegaFlashROM-SCC-SD?
3) will MegaFlashROM's SCC interfere with an SCC inserted (obviously) in another slot?
4) if I understand correctly there is a secondary (external) PSG, how is this implemented? Is it a real chip or inside an FPGA?
5) if there is an FPGA, what is used for?
Thanks

Hi Manuel, thanks for your reply.

1,2) is it possible to give a try with a 1chipMSX, please?

3) I mean mapper access, but that was I my lack of experience: investigating I found that SCC is memory mapped (not I/O mapped) so it is possible to have more SCCs connected, sorry for unnecessary question.

4) & 5) cool! This is very interesting for me. So there is also an EPCS device (or equivalent if you don't use Altera) that configures fpga at boot using active serial programming?

ONE day to go!!!!
tomorrow at 18:00 the inkoop actie will be closed
we have 12 people now

This is cool! I have the MegaFlashROM SCC+ and it's served me well. Just a quick couple of semi-unrelated questions -- What is the file browser used in the video? Is it something that comes with Nextor? Also, could you share that OPX collection ? I have some 50-or-so files gathered from various sources (spread on a bunch of diskettes). Is there some definite collection of opx songs I missed out on?

OeiOei: I didn't get an email?

Thanks luppie and Guillian!

The manual is online only.

And so... I'm a happy owner of this cart, but I cannot understand why a "getting started" paragraph for dummies is not included into manual...

Btw, video explains very well where is the main point:

before to start to enjoy the SD drive, do I have to copy some of these files http://www.konamiman.com/msx/msx-e.html#nextor into the MicroSD card and then launch SD2TOC to mount the card?

Another point: I have a 1GB MicroSD formatted with Windows 7 exFAT 32KB dim alloc. Is it all ok?

Thankyou Guillan, I've just "discovered" some steps.
But I would say it with simpathy in the MSX world, things are never clear and simple at a first sight... everytime you have to start a quest to understand every thing.
So I start my personal "getting started" guide for dummies:
- put (possibly <2GB) MicroSD into one MegaFlashROM-SD Slot; slot near the front is slot2, the other is slot1 (so wich slot to select?);
- start MSX2 with cart inserted, Multimente will be launched; press immediately ESC to go to A:\>;
- type BASIC to go in MSX-BASIC;
- type CALL FDISK to call partitioning software;
- follow instructions to format MicroSD as you want; be sure to select the ID of your MicroSD; format will be FAT16; in my case I want a full FAT16 1GB partition;
- be sure to save partition table, committing operations with W;
- reset MSX;
- select DRVINFO to have a complete descriptions of drives; note in a piece of paper the infos of the card (slot, subslot, unit);
- now in MultiMente you have to modify the SD2TOC.BAT, that contains a call to MAPDRV, with the right parameters (slot, subslot, unit) in order to map the C: with the MicroSD.

Is it all right?

Please help me to see this MicroSD...
Drive C: is not mapped to Slot1, in any case MAPDRV returns ***Invalid Drive.
Maybe the problem is that I have inserted the cart in slot 2 of the MSX, but it is a primary slot, so what the point...?

I am a little confused

For MultiRom the manual says: It is possible to put several games into the cartridge at the same time, as many as they fit in the cartridge's memory, up to 511.

The Specs say: 8192KB (64 Mbits) flash ROM memory

So the questions I have are:

1. Is the flash memory 8MB or 64MB?
2. So even if I put a 4GB SD Card in, using MultiRom I would still be limited by the 8MB (or 64MB) flash ROM Memory.

I have just downloaded 109 MSX ROM Files. These come to around 6MB, so if the limit is 8MB how would you be able to fit 511 ROM Carts in a memory that small?

I own two MSX2 which I got cheaply from the EBay. The MSX was not big at all in England so I don't think many people are into them here, and they do show up in the UK very rarely. One is a Philips VG-8230 with 192k RAM and the other is a Philips VG-8235 with 256k RAM (poor condition and controller port 2 is missing a pin). Although the VG-8230 is in much better condition and I guess most games will run fine with 192k RAM with no problems.

Also does anyone know if MSX games used one button or two button controllers, and whether the wiring of the joystick ports was different to other 8 Bit machines, like the C64 or Master System? If so does anyone know whether you can get MSX joystick adapters anywhere?

@Guillian: thankyou very much Guillian! These are the informations I needed!
So the "getting started" is very simple: put a <=2GB FAT16 formatted card into Slot1, this will be drive B:.
This cart is great! The embedded MM recognizes ROMs, DSKs and other formats and uploads authomatically into the flash!
If you want to erase ROM actually present into the flash, just push cursor up at the boot and choose the right menu item (usually option n.1 to erase Flash content).
Only one thing lasts: accessign the B: (the SD card) with a DIR command, hangs the MSX... But maybe it's a matter of wrong SD formatting from Windows. I'll repeat procedure with a more common FAT, choosing in Windows FAT / 16KB.
Thanks and soon with other experiments

Ok soo... all works very good, apart the drive access by Dos commands.
I go to the dos prompt, type B: and I'm into the MicroSD drive: then I use DIR, all files and directories are shown, but MSX hangs... It hangs while showing the number of files, free disk space, etc.
Same operation with MultiMente works. correctly.
Any help?

@enribar: Bear in mind that after a DIR command in DOS, you will need to wait while it calculates the free space. It can take a while depending on the size of the partition.

@Guillian: yes you're right! I leaved the MSX to calculate free disk space, and after 30 seconds the prompt appears again!
So MSX does not hang, I was too quick to press reset...!

Is there a solution to this "problem"? The 1chip MSX MegaSCSI drive displays free disk space immediately.
So:
1. Do I have to make smaller partitions?
2. Do I have to fullfill the SD card to speedup calculus? (=Does It depend to the number or size of files?)
3. Do I have to change COMMAND.COM version? (now 2.44).

@enribar: Are you using the same card (capacity/partition) on the 1chip MSX? The time should be the same.
Anyway, you can use Nextor's RALLOC.
I.e.: RALLOC B: ON

From Nextor "Getting Started Guide":
When a drive is in reduced allocation information mode, the Nextor function ALLOC, which returns information about the total and free space on a drive and is used by COMMAND2.COM to display the free space, stops calculating free space when it reaches the amount of 32MB and returns this number instead of the real amount. This causes the free space calculation time for FAT16 partitions to be significantly shortened, especially for very large partitions.

@Maggoo: You are welcome!

@MicroTech: SVeN reported he had problems using the cartridge on the 1chip MSX.

The definitive solution for the free space calculation time would be to patch COMMAND 2.44 so that it does not calculate the free space after a DIR command. Or better yet, it does or not the calculation based on the value of an environment string.

I've heard about a tough and wise man in the northern Spain that has the power to disassemble and improve MSX programs and has done it in the past with Multimente and others, but that's probably just an urband legend...

I confirm that MegaFlashROM SCC+ SD works on 1chip MSX!
Plugged cart into cart-slot 1 and mounts are:
- A: internal MegaFlashROM-SD's flash drive;
- B: MicroSD flash card;
- C: 1chip MSX MegaSCSI SD drive;
- D: 1chip MSX MegaSCSI SD drive (copy of C.

I have not burn any ROM or DSK into MegaFlashROM.
I have only opened a TXT file wih Ank and Kanji chars and works!
Operation done with MultiMente.
O.S. boot is the one of the MegaFlashROM, not the SCSI one (because the DIR command is slow...).

No, still the same annoying and blocking message.
My OCM is updated with the last KDL (OCM-PLD v3.2 RC2) improvement file.
OCM slots 1, 2 and SD card are "dipswitch" enabled.

The MegaflashromSD works fine with the GT.

@ SVen: what about trying MegaflashromSD (in slot #1) on OCM with the original pld installed?

Me! I ran the MegaFlashROM SCC+ SD on a original 1chip MSX, without any firmware update.
Results are:

I confirm that MegaFlashROM SCC+ SD works on 1chip MSX!

O.S. boot is the one of the MegaFlashROM, not the SCSI one (because the DIR command is slow...).

Update:
- Flashed ALESTE.ROM from MicroSD to MegaFlashROM and worked perfectly (all done at a very high speed!). After that, returned to default SD configuration with the cursor-up + F1.

Next step... Experiments with 4GB partitions.
It's time to program the "Next Generation MSX Software"!
Hi-tech software that could benefit of a very high speed and capacity mass storage device.

I already found out on my fat16 cf cart... It seemed like a diskdrive writes faster than that... At first I thought something was wrong, but it all seemed perfectly easy to explain...

You can mount different partitions using MAPDRV. I.e.:
MAPDRV C: 1-0 2 1-3 (mount in C: partition 1 of SD 1 cartridge in slot 1)
MAPDRV D: 2-0 2 1-3 (partition 2 in D)
MAPDRV E: 3-0 2 1-3 (partition 3 in E)
MAPDRV F: 4-0 2 1-3 (partition 4 in F)

I think Nextor will always mount the first partition in B (or the one with NEXTOR.DAT file in it)
On DOS1, you can try to make several partitions of 16MB and change them from BASIC using:
CALL MAPDRV(“B:”,2)
CALL MAPDRV(“B:”,3)
etc...

Yes, at boot time Nextor searches for primary partition compatible with the MSX-DOS version.
So I think a good configuration for a single MIcroSD should be:
- 1st partition 4GB (primary for MSX-DOS 2 boot);
- 2nd partition 16MB (primary for MSX-DOS 1 boot);
- 3rd partition 16MB/4GB (mounting partition (C for MSX_DOS 1/2);
- 4th partition ... (to choose).
Could it be?

Question about this: Isn't it so, that the boot partition of MSX always has to be FAT12?; and if so... isn't the maximum size of a FAT12 partition 32MB?

So if I understand correctly it's 'plug (a fat16 format card in) and play'...?

And what is csmile?

Tonight I finally got a chance to start playing a bit more with my newly purchased MFRSCCSD.

And well... Kinda also got myself in a bind this evening. I learned today how to use FDISK to create partitions on my SD card and made four partitions, one 4GB Fat16, one 2GB Fat16, one 1GB Fat16, and one 16MB Fat12. Then I put some rom and disk files onto the one partition (the first one, 4GB) that shows up in Windows, the other partitions do not allow a lettered volume to be associated with them for some reason. Then while the MFRSCCSD was initializing and launching MultiMente, I changed drives to drive B) and started to load some roms to play. Worked great! And hitting the UP arrow bringing up the Recovery options to erase the MegaFlashRom contents worked great as well.

Then, I decided for whatever reason, it would be a "Great" idea to see what would happen when launching a Disk file in MultiMente thinking it would place it as a new Disk Rom image. It did something for sure and started to launch a disk, then in the Recovery screen I thought it would be another "Great" idea to erase the Disk Rom... After another reset, I saw the disk file try to load as a rom again, so I hit F1 in Recovery mode to erase the Rom file. Then that's when I noticed that I was no longer able to boot directly into MultiMenti... I had apparently erased it. lol Now it was launching Nextor Basic. So in Recovery Mode yet again, I thought I would try to re-install the SD Kernal, and before I did that, I figuered it would be a "Great" idea to erase the SD Kernal before reinstalling it. lol So after 3 "Great" ideas, my MFRSCCSD cart doesn't load anything and cannot initialize an SD card.

So... obviously, before I do anything else as a fourth "Great" idea, I figured I'd ask what my next steps should be. I've read the manual for the MFRSCCSD and I've downloaded the OPFXSD.com which is what I will need to flash anything to the cart, right? And the first thing I should install I'm guessing would be Nextor.rom, only... where can I find this? I didn't really see this file available anywhere, even when checking Konamiman's website. I guess I would also need to find the "diskrom.rom" and "romdisk.rom" files as well, but I've been unable to locate these either.

Sorry for the trouble guys, but I guess someone had to break it first, and it might as well be me!

After keeping an eye on this topic, finally my wife bought me so micro sd cards, so tonight I'm going to hobby/experimenting (dutch; onzinnig klooien/frotten) with my new megaflash scc+ sd MSX toy.

Have a little question about dos1;
Is MSX-DOS1 possible under FAT16?
Or does Nextor have a dos1-like mode which works under FAT16.

Thanks for the tip to remove MultiMente. I don't like the programm.

And 1 (start-)parttotion FAT12 size 4GB is also possible under Nextor?

Or to make partition2 16MB FAT12 like enribar says?
And; Is it possible to switch boot partition (always/all the time)?

Hi ray, so this is the state-of-the-art:
- FAT12 and MSX1 with <128KB RAM you can create and manage max 16MB partition size;
- FAT12 and MSX1 with >=128KB RAM you can create and manage max 32MB partition size;
- FAT16 and MSX2 you can create and manage max 4GB partition size.
Each time you boot MSX with MegaFlashROM SCC+ SD, the cart auto-search for a partition to mount as drive B:

So usually and with the configuration I suggest:
- on a MSX1: drive B: is the 16MB partition;
- on a MSX2: drive B: is the 4GB partition.

Mmmh, it is better that you format SD with the FDISK utility:
- start the cart with the empty SD inserted;
- escape from MultiMente to A: ;
- go to BASIC;
- type CALL FDISK;
- follow instructions to make partitions.

Yes, you can make a DSK image file using Disk Manager or similar. Also, you can copy the files to a floppy or to a 720KB partition and then use FDSAVE to create the DSK file.
Finally, install the new DSK using OPFXSD name.dsk /id

Is it possible to configure your own romdisk? I've checked the romdisk.dsk in diskmanager and it seems to be just a regular .dsk file. Booting it in openMSX won't work, probably because of Nextor?

I formatted the Megaflashrom + SD ,made 40 partititions of 16 MB with _FDISK. I put MSXDOS on the SD card .

Then I used the DISK.ROM from RUMSX , used OPFXSD DISK.ROM/I1 , made ROMDISK.DSK in Disk manager with MSXDOS files added , used OPFXSD ROMDISK.DSK/ID , installed it . On my VG 8020 the romdrive starts up . I can change to the SD ( B: drive ) in basic by _CHKDRV command . On the VG8235 without diskdrive , it only shows the intro screen ( Megaflashrom and SD card are found ).

MSX-DOS does boot on the VG 8020 from romdisk . There was no problem with the cartridge , just didn't work on the driveless VG8235, NMS 8280 and VG 8020 working well.

This evening I will try MFRSS on my driveless TurboR GT.
In the past someone tried to physically mount a second drive on the GT, unsuccessfully, and now it start only with a boot-floppy-disk inserted...

I can open the 720kB image in diskmanager indeed, but if I insert the DSK in openMSX after it's been booted to basic and give FILES commant, I get a Disk I/O Error. Is this intended? I thought it was just an ordinary file based DSK...

I've succeeded to extract all the files (including those in directories) with the Japanese DiskExplorer : http://hp.vector.co.jp/authors/VA013937/editdisk/index_e.html (Disk Manager can't extract the directories).

Then I've created a new DOS-2 formatted DSK with Disk Manager and used the Japanese DiskExplorer to transfer all the files (including those in directories). Guess what ? Now the DSK can be read normally with FILES or DIR ! :)

Oh... Nice... I can't flash a rom or dsk anymore with opfxsd O_o
I get as far as ooooo........... and then the system just freezes...

Ehm... help?

Oh... As soon as it didn't work anymore from the sd cart it worked on just a few minutes ago, now it works again from another cart... Must be sd cart related...

so there
i replaced the original autoexec.bat with one that suits me more
and it even works

but
i put this line in it too
SHELL=A:\COMMAND2.COM

and it seems it doesnt like that (file not found?)

my autoexec.bat as it looks now;
path=b;\m;b;\utils
mode 80
a:\mapdrv c: 1-0 3 1-3
alias /l b:\alias.dat
set expert =on
ver

OPFXSD EXAMP1.DSK /D1
OPFXSD EXAMP2.DSK /D2

Thanks both for explanation. Okay, but you have to type separate commands for each disk as I understand. It can't be done in 1 commandline for more disks?

Cool megaflashscc+sd-in-1chipmsx movie Luppie btw

You can write a batchfile for it... I just trial and errored (without error) to make one for Akin

copy con akin.bat
opfxsd akin1.dsk /d1
opfxsd akin2.dsk /d2
^z

This way you could make a dir filled with batch files for (multiple) disk games...

Making batchfiles for every multiple diskgame was not exact my intention (...still thanks for thinking with me, Meits!).
My question was: if there is perhaps a one-command-line-way to load multiple disks?

That's the misfortune of such huge mass storage devices, so many games. But then again, I bet you won't play all at the same day... If you want to play one, you can make a batch file... That way I bet it's hardly any labour... It might be something Nestor could make a .COM file for... For example flash akin1.dsk+akin2.dsk which executes opfxsd akin1.dsk /d1 followed with the same thing for disk 2...

Idea: Let's compile a list with feature request (I got two in mind already )

OeiOeiVogeltje started this Topic :-D

Guillian, how do i discard the sd interface so the computer boots from floppy diskdrive?

Thanks for support again.
Sorry for bothering you, but this information isn't in the manual.

With this kind of information added it becomes a super device more and more.

now i am curious...

Tomas, nice to hear you got it working, but I think you chose the hard way
I mean, you downloaded Nextor.rom instead of NExtor kernel for recovery. The first one you need to install it from another disk interface (what you did). The second one can be installed from recovery (easy way)
Also, once the Nextor kernel is installed, the SD interface will work. So if you put in it MSX-DOS/Nextor files, the cartridge will boot the operative system.
From there, you can flash ROM disK DSK using OPFXSD (all in you SD card)

About the cartridge does not initialize on power on. Just install the recovery ROM I linked in my former post:
RECOVERY.ROM
OPFXSD recovery.rom /i34

About ESC not preventing the ROM in MegaFlashROM SCC+. What ROM did you flashed and how? ESC will not work if you set a different key with /Txx option.
Just erase you current game from recovery with F1 and write another game for testing.

I installed a .dsk file with OPFXSD .dsk /i1 option .After that the installed rom on the flash cartridge didn't start anymore , and the SD card was not recognized anymore . I tried recovery.rom , installed the diskrom again , erased the flash cartridge , no result . Erased the SD kernel also . How can I reinstall the SD kernel ?

I mistyped . I installed a .dsk image with /d1 option ofcourse . After that the SD drive was not recognized anymore. The SD kernel was stiil installed then .I thought it would help if I removed and reinstall the kernel .

I tried F4 option with KERNELD.DAT file on SD card , it said ' SD card init error ' . In my SD/MMC card reader however, the SD card works well . The diskrom file is installed on the Flashrom .

Thanks . It's working now . Formatted in FAT through Windows , then Installed KERNELD.DAT with Recovery F4.
Nextor boots , when I go to MSXDOS it only shows 133120 bytes free though on a 2 Gb formatted card ?

I am having two problems:
1. I have 140 ROM files I want to use. After copying 110 files, no more files will copy to the SD card although it appears there is still space on the card.
2. Using the above tutorial (7 posts up here), I have added 110 filenames into MULTIROM.OPF and also copied OPFXSD.COM to the SD Card. From a B> prompt when I then run the command OPFXSD /O on the MSX2 it displays the following:
Loading MULTIROM.OPF.

Processing MULTIROM.OPF...
1942.ROM
Opening file : 1942.ROM

Usage: (OPFXSD (filename.ext) [/opts]
Example: OPFXSD MGALIOUS.ROM /k4 /e

Options:

It then shows a list of all the switches and options and returns to a B> prompt. It does not add any files. I have also tried making bubble bobble the first file in the MULTIROM.OPF file (as shown in the example on the tutorial as this should need no switches) and the same thing happens. Please can someone tell me what I am doing wrong?

Thank you for the reply.

1. They are different sizes, but I thought the multirom menu was built into the cartridge - not a file on the SD Card. I guess this could be related to the FAT12 and file sizes though.

2. I have a Philips MSX2 VG-8230 and a VG-8235. I was trying the VG-8230 last night. Interestingly it is behaving like a MSX1 with the cartridge and not loading the file software on boot like a MSX2 should do. When I plugged it into the VG-8235 it is loading the MSX2 file software on boot and OPFXSD /O is working like it should. Would be interesting to know why the VG-8230 is not working.

3. A new problem - It appears the cartridge menu loading software is limited to 3 pages and 90 files. Is there any way to increase this so it shows all ROM files that have been added rather than just the first 90?
