I bet you like inaccurate audio emulation too lol. That's my biggest nitpick with ZSNES honestly. Even Super Mario World sounds wrong.
Oh man you would shit bricks once you hear the difference with a more accurate emulator. Snes9x is really good now.
the snes 9x I know is the one for the Wii, and it seemed clunky. To be fair, I was using a really huge compact Rom hack of Chrono Trigger (FoE), so some unstableness is expected. But then again, ZSnes doesn’t have any problem handling that...
