The iso games i put in my <root>ISO folder do NOT play all the time! the "demo" screen will start to play but when i load it it doesn't work! Some things to know about my psp: i have lots of HomeBrew games on there, i have a 4 gig SONY MagicGate Pro duo memory card, 3.40 oe-a is my current firmware, the only game i can get moderately working is Ratchet and Clank size matters. Right now i'm trying to play Brooktown High (just to spoof it if you need to know) My friend got it working on his 2 gigabyte memory stick. WTF?!
