Aaltera DE1 MSX newbie

Hello there

I've just received my Altera DE1 board and I want to star with MSX, of course.
I'm using the latest HRA! core, but I am missing some info here: according to the guide in http://msxbanzai.tni.nl/computers/ese3.html , I need the following roms:

MEGA-SD.ROM (64 kB)
MSX2BIOS.ROM (32 kB)
MSX2SUB.ROM (16 kB)
MSXMUSIC.ROM (16 kB)
KANJI font ROM (128 kB)

It's ok for most of them, but.. what's that MEGA-SD.ROM? Is it the MEGA SCSI rom? Is it needed for boot?
I know you guys can't help me with BIOS files, but maybe a PM wouldn't be a bad idea... :D

..and...does the DE1 implementation use the same file names for bios files as the OCM one described in msxbanzai.tni.nl??

Thanks!

Why do they need you?
All you need to work OCM is in POF-file, including those ROMs.

By the way, the last HRA! core requires the next ROMs:

65.536 (00-07) (DISKBASIC) OCM-MEGASCSI.ROM MEGASD.ROM
32.768 (08-11) (MAIN-ROM) (FS-A1WSX) MSX2P.ROM
16.384 (12-13) (EXT-ROM) (FS-A1WSX) (MOD_$2C8D) MSX2PEXT.ROM
16.384 (14-15) (SUB-ROM) (FS-A1WSX) MSX2PMUS.ROM
131.072 (16-31) (KANJIDATA) OCM-KANJI-128KB.ROM KANJI.ROM
16.384 (32-33) (SLOT0-1) ($0000-$3FFF) FREE16.ROM
32.768 (34-37) (SLOT0-1) ($4000-$BFFF) MSXKANJI.ROM
16.384 (38-39) (SLOT0-1) ($C000-$FFFF) FREE16.ROM
16.384 (40-41) (SLOT0-3) ($0000-$3FFF) FREE16.ROM
16.384 (42-43) (SLOT0-3) ($4000-$7FFF) XBASIC2.ROM
16.384 (44-45) (SLOT0-3) ($8000-$BFFF) FREE16.ROM
16.384 (46-47) (SLOT0-3) ($C000-$DFFF) FREE16.ROM

Why do they need you?
All you need to work OCM is in POF-file, including those ROMs.

Hi, i'm interested too, but i'm a little confused. Are you saying that the needed ROMs are already someway packed in the pof file? Because i already opened the pof file in quartus and in a text editor and can't find nothing relevant to the ROMs needed.

I already found some ROMs needed:

MEGASD.ROM : No idea where can i get this ROM.
MSX2P.ROM : CRC32 = 358ec547 | size = 32.768 bytes | filename in openMSX is: fs-a1wsx_basic-bios2p.rom > Seems correct.
MSX2PEXT.ROM : CRC32 = b8ba44d3 | size = 16.384 bytes | filename in openMSX is: fs-a1wsx_msx2psub.rom | [0x2C8D] = 0x3A,0xF8,0xFA > Seems correct.
MSX2PMUS.ROM : CRC32 = b8ba44d3 | size = 16.384 bytes | filename in openMSX is: fs-a1wsx_msx2psub.rom > Seems correct.
KANJI.ROM : CRC32 = b244f6cf | size = 131.072 bytes | filename in openMSX is: Panasonic_FS-A1FX > Seems correct.
FREE16.ROM : CRC32 = ab54d286 | size = 16.384 bytes | Created in a HEX editor a binary file that has 16.384 bytes filled by 0 > Seems correct.
MSXKANJI.ROM : CRC32 = a068cba9 | size = 32.768 bytes | filename in openMSX is: Panasonic_FS-A1FX > Seems correct.
XBASIC2.ROM : CRC32 = 2825b1a0 | size = 16.384 bytes | filename in blueMSX is: Generic European MSX2+ > Seems correct.

The way you put the list of ROMs needed seems to me to we need to concatenated all this ROMs in a big final file that we put on the SD? If so, then i only need the MEGASD one. I think it's free to distribute?

Thanks, and pardon for all the question, but in my case i'm a total newbie with this, and a little help would be appreciated

File emsx_top.hex converted to emsx_top.bin
The first 64 Kbyte of the BIN-file and have MEGASD.ROM

MSX2P.ROM : CRC32 = 358ec547 | size = 32.768 bytes | filename in openMSX is: fs-a1wsx_basic-bios2p.rom > Seems correct.Yes.

MSX2PEXT.ROM : CRC32 = b8ba44d3 | size = 16.384 bytes | filename in openMSX is: fs-a1wsx_msx2psub.rom | [0x2C8D] = 0x3A,0xF8,0xFA > Seems correct.Yes, but [0x2C8D] putch to 0x3E, 0x84,0x00

MSX2PMUS.ROM : CRC32 = b8ba44d3 | size = 16.384 bytes | filename in openMSX is: fs-a1wsx_msx2psub.rom > Seems correct.

More questions from a total newbie, too:

1)How should we convert emsx_top.hex to emsx_top.bin??
with hex2bin, maybe??

2) How can we add the files to a big POF file? copy /B file1+file2+file3 is correct??

3)What else do we need to be in the POF fle? only those ROMS or something else??

4)What should be the name for the POF file in the SD?

5)How can we extract the MEGA-SD.ROM file? with an hex editor? or how??
