One chip MSX improvement project

The weird thing with the "Fast VDP" option is that it also fixes some games (not 100% sure about them, RadarSoft's Breaker, maybe also Gauntlet). If confirmed, that implies that the "normal" VDP speed or accesses have some issues...

Breaker seems to work correctly on openMSX in 60Hz, on openMSX (will check on real machines tomorrow).

About Randar, it indeed does not work yet. As this one is a Compile game, maybe the fix will be the same as other Compile's game. Checking it now...

Quick workaround: open the randar.dsk image with DiskExplorer (or another tool to browse the contents of disk images), extract and copy the files to a directory on your SD card and launch AUTOEXEC.BAT.

EDIT: Looks like even with this solution, Randar crashes at line 740 on an open "MEM:RPG.DAT" instruction... That vaguely rings me a bell... Do we need to initialize memory disk or something ? (that is not working so well in MSXDOS 2 or Nextor ??).

Hi @louxthrax and @Vampier,
Thank you for talking about Randar.
I confirms it is working on MSXDOS2 with mm and fd* tools.
I can play it and save on the dsk file. There is 4 rooms to make saves. It will be good to have a way to play it in Sofarun Is it the same case as game patches for randar 3 or it is not the case ?

Thanks,

Perhaps it's possible. But I don't own a de10nano, so I can't offer it.

Thank you for your great work!
