This game is incredibly slow when I play it with 1964 and also the graphics are pretty buggy. What plugins or emulator do you suggest I use to play this game?
Try Project64 and the Glide64 plugin (if your card is good enough to handle it. IIRC, the problems with Vigilante 8 are well known, so don't expect stellar results even with PJ64 and Glide64.
