hi sorry if this wrong place but anyone know a list of rom file types for dingux emulators??
That info ought to be included on the list - a good point!
Atari 7800 is .A78
Atari 5200 is .A52 or .BIN
Atari 2600 is .A26
Another Atari extension is .ATR, but I'm not sure, perhaps that is Atari 800
Dingux Hugo (PC Engine) is .PCE
SEGA is still .SMS or .SMD
Mostly, the extensions are what you would expect them to be, if you have any experience at all with ROM files.
