My cabinet consists of a Tekken Tag cabinet, P4 2.9GHz processor, 1GB RAM, 80GB HD, Arcade VGA card, IPAC 4, EMS Top Gun II, hopefully thats enough info on hardware for now.
It seems to lock up when playing the PC versions of House of the Dead, 2 and 3. I've been able to play 1 for a little while, but the other day it locked up on me too. I've played Police Trainer on MAME for a few hours sometimes without any issue, but the last few days it has locked up on me twice, it's just intermittent. I've been able to play these games just fine on my regular PC.
Any ideas?
