Hey all,
Sorry if this is duplicated info from another topic or something, but I can't find the answers I need anywhere.
I received a 2-slot Megaflashrom SCC+ SD for Christmas from a very generous friend, but am having a lot of trouble getting it to work. I initially had trouble even getting my system to recognize the existence of the cartridge, but after using options F1, F2, and F3 from the recovery menu, then reinstalling nextor.rom /i from a floppy disk, that's no problem anymore. However, I have a base MSX2+ with 64 KB RAM, so I can't use Multimente as an operating system (which requires 128 KB RAM). So I figured the cartridge would boot into MSX-DOS on startup when I put an SD card in.
...Instead, however, it's recognizing the Megaflashrom, but booting into MSX BASIC. And when I type CALL SYSTEM or _SYSTEM, it just reloads MSX BASIC again. No matter what I do, I can't seem to access the many ROMs I copied onto my SD card to install them to the Megaflashrom.
Can anyone give me any advice on how to make this work? All the tutorials and such that I'm seeing online are for systems with 128 KB RAM, and I'm finding precious little information on how to work with this cartridge on a system with only 64 KB.
FYI, the system is a Panasonic FS-A1WX.
Thank you!
EDIT: I should note, I also tried inserting an MSX-DOS boot disk with OPFXSD.COM on it, then holding Esc on startup to have it ignore the Megaflashrom SCC+ SD and just boot from disk, figuring I could run OPFXSD that way to get around the issues I'm having booting from the SD. However, even when I hold Esc on startup, the system is still booting into MSX BASIC, ignoring the disk -- and even when I type CALL SYSTEM or _SYSTEM, it still just reloads MSX BASIC. I can't access the disk at all.
EDIT2: I should ALSO note that if I pop the SD card out (but leave the cartridge inserted) and hold Esc on startup, I can boot from the disk, then put the SD card back in. This way, I can run OPFXSD from floppy disk. However, when I do this, OPFXSD just exits with a "MegaFlashROM SCC+ not found" message. Seems I just can't win!
