I can send you scans of you want in order to show them in the UI of the emulator.

Nice job.

I working for it and need floppy disk scans and tapes pictures.

There is always the possibility to limit certain functions to gain speed in a special version of the emulator, it’s an extreme view, which concerns only part of the games. This is another work that is not the purpose of msxDS.

Emulation «customized» for each game allows, of course, to have a significant gain on the emulation speed (you can free up memory ITCM, remove screens and modes of unnecessary devices).

I will add your proposal for a management «cheat code» to the list of things to do, although there are solutions to many games (http://msxsolutions.msxblue.com/).

By the way, a little suggestion: maybe you could implement a way to find and apply «pokes» to get extra lives, etc.

The crc32 of A1WXKDR.ROM is A068CBA9. B4FC574D is the crc32 of FS-A1WSX kanji ROM that you can use too.

Fortunately, the problem with Goody was not so hard to find. A comparison of blueMSX and msxDS was enough. The registers were saved in a file, and then were compared with the same configuration on blueMSX.

Some types of SRAM, such as the PAC / FMPAC, do not work with msxDS, it should go better in the next version. But in the near future, the management of slots, the VRAM and the frequency of the CPU should be reworked.

By the way, I think this line:

if(R->BC.W) { R->AF.B.l|=N_FLAG;R->PC.W-=2; }

should be changed to:

if(R->BC.W) { R->AF.B.l|=(N_FLAG|P_FLAG);R->PC.W-=2; }

since flag P must be set if BC is not 0 (maybe an interrupt happened during the LDIR). And this change comes for free, it doesn’t take any memory or cycles at all 🙂

We must remove the optimization of both the Z80 instructions: LDR and LDDR to solve the problem that causes a shift in the address pointed by the PC register. In Goody, there is an LDR that copies a block of data «on itself», LDR is replaced by an XOR A and the Z80 continues to work normally.

Like this:

// do
// {
WrZ80(R->DE.W++,RdZ80(R->HL.W++));
–R->BC.W;ICount-=21+2;
// }
// while(R->BC.W&&(ICount>0));

for MSX 1 mode:
MSX.ROM = National CF-2000 or FS-4000 ROM (CRC32: EE229390 or 071135E0)

for MSX 2 mode:
MSX2.ROM = National FS-4700 or FS-5000 ROM (CRC32: 9B3E7B97 or A44EA707)
MSX2EXT.ROM = National FS-4700 or FS-5000 ROM (CRC32: 4A48779C or 43E7A7FC)

for MSX 2+ mode:
MSX2P.ROM = Panasonic FS-A1WX ROM (CRC32: 19771608)
MSX2PEXT.ROM = Panasonic FS-A1WX ROM (CRC32: B8BA44D3)
KANJI.ROM = Panasonic FS-A1WX ROM (CRC32: 1F6406FB)
A1WXKDR.ROM = Panasonic FS-A1WX Kanji Basic ROM (CRC32: B4FC574D)

for PSG+FM sound mode:
FMPAC.ROM = Panasonic FM-PAC BIOS ROM (CRC32: 0E84505D)

for Floppy Disk Drive emulation:
DISK.ROM = Panasonic FS-FD1a Floppy Disk Drive extension controller ROM (CRC32: 697EAF4E)

Alex: What type of flash card adapter you use?

No sé mucho de desarrollos para Nintendo DS pero necesitas el parche DLDI para que te funcione, aunque en la mayoría de las tarjetas no es necesario… Lo que puedo hacer es pasarte por email la carpeta completa de mi instalación (que no es esta última actualización) a ver si te funciona.

Ya me contarás.
