MAME compatibility list
This is an incomplete list of compatibility issues that MAME has with different systems.
Contents
Nintendo
NES
The PPU for this core is per-scanline, so mid-frame effects generally don't work too well. The only reason it can even handle MMC5 games is because of hacks! It really needs a video system rewrite and BAD.
SNES
Many timing issues here. It's probably not even as accurate as SNES9x. It really needs to be reworked.
Nintendo 64
This whole system has tons of timing issues. Tread lightly, and remember to use -nodrc on this one, as their dynamic recompilers for this system are currently broken, and result in Spiky Polygon Syndrome.
Sega
SG-1000
Nearly perfect.
Master System
Pretty damn accurate. MAME is quite a good emulator for this system.
Saturn
It's about as good as Yabause, more or less; just with much nicer code.
