the biggest problem is that the emulator fucking sucks at reading inputs.
i didn't think it would be too hard to adjust between emulator and ps2, but it is. i was dropping jump cancels on saturday because i was used to overcompensating for the emulator's crap command interpreter (since my ps2 is currently broken, but i'm getting a new one this week anyways).
so uh, i would recommend that you just get a ps2 and ac. if you wanna spend a grand just to play this game, you're much better off getting a naomi and the gd-rom, lol.
