Oh and SymStudio has a Screen 8 256 colour convertor which look even better Hint hint.


Ok, maybe in SymbOS 3.0

Quote:

Perhaps we should have a Backdrop competition with the winners being distributed with all subsequent Symbos releases! Well that my suggestion to get people using it


Good idea, I just wonder what is a good place, where people could upload the pictures for the competitions...

@MSD: I promised you to come to Groningen this year! GFX9000 is not the issue, but 256 colours...

I am now trying symbos with simpsons and a local program videos ^-^. It will be cool to use the MP3 cart to reproduce the video sounds Also, I will buy a 1GB CF card only for SymbOS

This might be a stupid question, but how you convert full screen 512*212 images? It seems that maximum x-axis resolution in SymStudio is 256.

The x-axis value is in number of bytes. 256 bytes, 4 bits per pixel -> 512 pixels.

SymStudio works in Bytes width as that is what symbos uses internally. If you have selected Screen 7, and then made the image 256 Byte width 212 Pixel Height then the image is 512 x 212. Above the little preview image in the bottom left it actually says the X and Y dimensions.

Also please note that to save as a background image you have to click the Save a backgorund image tick on the file selector when exporting. Otherwise it will become a normal image the maximum width of that is 504, so it will be cropped a bit.

Anyway its good to see people trying to use symstudio. If anyone wants to make a disk image of backgrounds/pictures I'll happily put them on the symstudio site so everyone can share them.

I'll get back to SymBasic now then

Maybe SymStudio could better display the width of an image in pixel?

Some infos about possible image x-sizes and background pictures:
- internally SymbOS can't plot images with a bigger x-size than 255 pixel
- by using offsets you can still display larger <<linear-stored>> images in multiple steps
- in this case the maximum width is 255bytes (4 colour gfx) or 254 bytes (16 colour gfx), which means 508pixel in Screen5/7 and 1020pixel in Screen6; the maximum size of a single image is always 16K (because of the memory mapping)
- 16 colour gfx have to have an even x-width in bytes
- an SGX graphic can have more or less an unlimited size, both X and Y. This is done by putting several linear-stored images one after each other
- for the desktop background pictures I choosed a special arrangement of single images. The reason was, that I wanted to prevent memory fragmentation and keep the amount of image-strips low. So the first three parts are 152x212 pixel (=8k or 16k), the last one is 56x212 pixel.

I can't make SymbOS work on my TurboR

I once made it work but now it doesn't. Let me explain my configuration:

MSX TruboR A1GT + Sunrise IDE+RS232 + Seagate LBA Hard Disk (I had once a problem with a CHS disk so I got this LBA).
I formatted my hard disk and put Symbos in the first partition (A: ).
Launched it with SYMBOS F0
The desktop shows, the cursor moves but when I try to open any application it gives me "Error while loading: A disc error.... (error code 00)".
I've tryied with the SYMBOS-ide-p1.INI file, with the standard one, copying it to other partitions, with SYMBOS F0 M6 (it gives a "Disk error while booting SymbOS MSX" )... I tryied to read every TXT and searched this forum with no luck...

Any ideas of what am I doing wrong?

Thanks!

Moderators please could you possibly create a thread with many categories for symbos?Symbos is one of the biggest msx projects and we are all actually very excited about this.

However the large number of posts make it very hard sometimes to find help or ask question and expect a good answer.Maybe giving moderator powers to prodatron and allowing him to setup the threads in a convenient manner in any way he thinks it should be ,would be a good idea.In that way i think that
1st)Prodatron and all people responsible for programing or developing for Symbos can exchange their ideas fast.
2)People that would need help as in my case or Kliis would get faster response.
3)The specific thread would not be with so many posts
4)It would be easier to have access to past archives in order to find some info.

Terribly sorry if this is not the place to post this.I think symbos is the greatest thing for our beloved msx machines and every time i see a new post from prodatron or others i feel so happy.It is just that sometimes it is not easy to easily find what you want on a thread with 138 pages.

Prodatron keep up the good work,you are the best!

Any chance that mp3 cartridge could be supported?(nothing better than having symbos with mp3 support!),Or would you support the megaflash scc cartridge?So it could be manipulated under symbos in order to flash it with new rom files,load existing rom files from it,delete files from it,display statistics like how much of the flash rom is free or not,and of course the biggest advantage of megaflash cartridge: the scc chipset from konami.How about the thought that symbos could take advantage of that?

Best regards

It's free for anyone to start a new thread related to SymbOS. Whether a dedicated forum category might pop up is or not is not even relevant for that, because if it does then all we have to do is move those SymbOS threads into this new category. So, those who want a new thread: make a new thread!

I actually think ppl make it a sport to see how far this thread can stretch, and are therefor reluctant to start a new thread.

I think that the one thing that's very clear is the crosstalk, completely chaotic and related to tens of other SymbOS subjects. If one starts about those truncated pictures, ppl end-up talking about the converter, about sc8, about G9k, about screensizes. If people talk about SymbOS applications, they end up talking about tools to make applications, which leads to talks about SymStudio. Before ppl end-up at SymStudio, there're talks about purposes, uses and potention, which leads to talk about conventions like what an MSX-trackers looks like.
This may be chaotic, but at the same time it's interesting.. it's like WIKI, you never know where you'll end. Seperate treads might look cleaner, but would they invite the positive aspects of crosstalk?

What if this long thread stays as 'main news'-thread? Would people end-up staying here, as a kind of "cosy place", or would they all migrate to new threads, leaving this long thread to die in peace?

This thread is so large that it works like a magnet, and becomes its own subculture. Kill one and you're a murderer, kill a million and you're a conquerer. It means that this thread is so big it's perhaps hardly 'just a thread' anymore, its role changes. Just imagine this whole thread would've been wiped for some reason.. I think that would actually be like wiping away a whole culture and a large/important/interesting history. I expect ppl to be addicted to this thread, perhaps even feeling emotionally attached to it. Such is the influence of this thread.
(and I just *know* ppl will want to see the 200 pages milestone )

What if people have problems finding back an issue? Perhaps there could be a sticky/locked thread with a brief summary of each page of this thread?

It must be said this thread is kinda cool, and I do feel sort of attached to it in a weird way. And yes I'm a CPC fan really but I'm far more likely to be looking at msx.org than cpczone.com which is also a little strange.
From a personal point of view I'd never even thought about the MSX, as being from the UK it wasn't exactly a viable option in the 80's. Not sure how much Prodatron knew about the MSX either, but I think we've all been suprised to find this community so vibrant, and the fact it has embraced what was in effect another macines OS is quite remarkable. Secretly I actually think that you lot love the idea that you've hijacked Symbos and turned into a mainly msx lead project.
Now I'm not complaining about the CPC scene (except I am), but I doubt very much that Prodatron would have gone much past version 1 given the support and interest he's had from the amstrad scene. Go to cpczone and see how many threads and replies there are about symbos - cos it won't take long.
I guess what I'm saying is this thread is as much responsible for what Symbos currently is as Symbos is responsible for this thread.
Here's to the next 140 pages
