Rainbow 100 machine detection that I wrote looks at two memory locations to see if either says "Rainbow," so it might fail on alternate or foreign language ROMs...
@jba Does it work on emulators?
@xmanmonk The only Rainbow 100 emulator that supports graphics is in MAME, and it's a catastrophe. But the system check should work since MAME is using actual ROMs (if you can even find them).
