alright, i had 1 psp. the screen cracked i bought another screen. then i also bought another psp. both psps are v 1.5. im buying katamari tonite. i was planning on selling one of my psps. but if i cannot play katamari on 1.5 then i will be forced to go to 2.6 on one of them. but the thing is. should i upgrade the crappy one and then sell it on ebay and keep the good one at 1.5?
