hey please bear with me as this is my first post, i have a import psp (usa) today i went from 2.71> to 1.5> 3.40 oe-a but my iso's never seemed to work, which ever one i put in! (i think its worth mentioning that UMDs DO play!) only tekken dark ressurection iso played once and never again, i have tried all sorts of things today, going down and up to various other custom firmwares, playing about with recovery settings, triple checking iso's are in iso folder, formating the flash 1 folder, what else can i do to get them to play? all i get is 'game could not be started' error, or a black screen, please help, im going nuts lol! i hate 3.40 oe-a GrRrR!!!!!!!!!!!!
