Firstly I'd like to thank everyone envolved in scummvm for making such an amazing program.
I can run scummvm no problem on 2.0 thru Fanjita's loader, I was just wondering if the 333mhz, version was compatible as I have had no luck with it.
I don't have a >= 2.00 FW PSP, so I wouldn't know.
But I've heard the loader allows you to set the clockspeed before running something (?), you might try setting it to 333mhz and using the stock 0.8.2 release if it does.
