@ -18,6 +18,25 @@ TODO:
-Minor graphic glitches in Royal Queen (cross hatch test, some little glitches during gameplay),
presumably due of the unemulated wait states on the comms.
Notes:
-Night Gal Summer accesses the blitter in a weird fashion, perhaps it fails the ROM check
due of address line encryption?
