Tomb raider iso turns off psp!!

I have a few psx games that ive ripped using iso producer and then compressed to a eboot and these games have worked great and work great on the psp. I lately did tomb raider the last revelation, did everything correct and when it loads i press new game then it freezes and turns off the psp, would anyone know how to stop this from happening and to get this game working as its a great game. Thanks in advance

 

firstly what firware are you on. earlier custom firwares have a fault which causes tomb raider to crash after the menu

 

Yeah sorry i should of put that down at first, im running on 3.52m33-4.

 

try upgrading to 3.71 m33-3 with 1.5 addon. but a better choice would be to use dark alexs popsloader plugin and select the 3.03 popsloader

 

i would keep it as the iso.

 

I tried that but when i put the iso into the iso folder which is in the root of my memory card the game dont show up on the psp???

 

i'm having the same problem with Tomb Raider Anniversary with my psp switching itself off. i'm running 3.71 m33-4 and when i try it with either the ISO or the CSO, my psp just switches itself off after the psp splash screen.

Any hints people ??
