@boelze said in ?SN Error on XROAR Emulator:
I have the exact same issue as OP.
Tandy CoCo games give me the ?SN Error.
For others looking into the issue of coco roms and the screen error ?SN Error seen when running coco roms...
"The "XRoar" coco emulator is a coco 1/2 emulator, and doesn't support the coco 3 functions. The rom image you are using most likely requires a 512k coco3." - @DABONE
