Other games that randomly crash.

Any suggestions on how I could help troubleshoot 3 gaames I have that crash with issues most likely unrelated to direct access.

One is Capsule Monster COlluseum. The randomness at which this crashes is astounding. it can go anywhere from 5 seconds to 30 minutes, with no rhyme or reason ti it's crashing, but i know that when it crashes the music continues for about 15 seconds before it stops.
The other two games aren't random in their crashing. all it takes it leaving it open a few seconds at the game select menu for midway arcade treasures 1 OR 2 and it will hang solid.

Anyone looking into those> should I make an ISO and send it over to crazyc for development puroses only (and thus legal)? CApsule monsters is a small game (1 gig)

shadow hearts 2 covenant is one of my favourite games, normally within 5 to 10 mins it'll crash randomly , and my dvd laser is stuffed now aswell so ive been waiting a long time to play it . I got 3/4 of way through then my laser refused to boot anything any more , hopefully one day ill be able to finish it using HDL

Seems the crash isn't as random as I thought it was. I managed to get capsule moster Colluseum to crash exactly the same way twice.

I started a free battle, selected bandit keiths stage, set out a certain assortment of monsters, and as soon as i selected my GOkibore it froze, with the musc dieing 5 seconds afterwards. but I can still find no rhyme or reason to what makes it crash. When playing from the real DVD, it often is seen pausing for a few seconds at seemingly random times while stlil leaving the music playing but it *always* continues. I'm beginning to suspect this is a clever copy protection system. The game is NOT dummied in any way, so i suspect it may REQUIRE being as slow as the real thing (not as slow as the outer areas!)
PS: WIl someone try this game in usb advance? i suspect it may work there 100%
