Greetings. I'm having a problem with the game Joust... It seems to gag intermittently during play (momentary slowdown, sprites disappearing).. I'm running MAME 32 .68 on a P4 2.4 Ghz with 1 GB RAM.. No other processes running in the background. I have tried fooling around with the display settings in MAME (v-sync, triple buffering, etc).. but nothing seems to work.
I'm pretty sure the ROM is ok, since the same file runs fine on my friends P2 550.. I can't stand his incessant mocking any longer.. I ask for your help!
