I have this problem too but I can't even get into the game. It loads the rom but before it can even get to the N64 logo it crashes. I have posted this before but noone could help me, at the time...
Game works fine if I boot into Windows ME but when I restart and boot back into XP it crashes like always. PJ 1.3 works with it still but not 1.4, don't know why. In case you can't tell, I'm dual booting at the moment...
