Got a slim psp today and stuck 3.71 m33 on it and all is working fine , but have a couple question about it. Best no umd setting is the sony one right?. That's what I have it on now and seems to be working fine , but there was another , m33 something. I know the custom firmware has the ability to set the psp to 333Mhz or something like that , but if I don't touch anything on the recovery menu , will the psp be stuck at the lower speed or will it just be default? and use what ever the game says to? (god of war uses 333 I think). CSO games do these run worse that normal games?. I know they are compressed , but I figured that would just add longer loading times , but my demo of God of war is a cso and seem to stutter a bit when entering new areas where loads of enemies appeared. So not sure if that's just the game or whether it be cause it was compressed. Finally , is it just me or does the analog nub hurt. I'm used to playing me DS , but after playing god of war and then killzone on the psp , my thumb was dieing. Thanks .
