Bad news for PSP Custom Firmware owners I’m afraid, as TheSixthAxis has reported that the Gran Turismo UMD / Download requires firmware 6.00. And of course Gran Turismo will only run on Firmware 6.00. So if your on custom firmware, your out of luck. At this stage your forced to upgrade to official firmware 6.00 if you want to play the game on CFW. Also they have reported that PSP GT has no structured career mode, unlike other Gran Turismo titles. I find this strange and a bit disappointing to be honest.
I guess I’ll have to run the update and then Pandora + DCv8 to flash back to CFW to play my homebrew and emulators. That is till PSPGen release 6.00 GEN….(if they do)
