ISO folder games help

ok so im back again... still having the same problem. im running 3.80m33-5 latest dark alex ... Fat PSP with 1.5 Kernel add-on. ISO folder in Root... 1.5 kernel selected in Recovery. pressed select in XMB and tried Sony NP9660, OE isofs, Normal, M33 driver. The game shows up great on the Memory stick .. Metal of honor heroes 2 background with music. I've even got a UMD in for the hell of it. if I click X to play, it does the PSP logo and then just returns me to XMB and says the game cannot be loaded. I tried another ISO/CSO some AVP game and it did the same thing except just hung at a black screen after PSP launch logo. Can someone give me a hand? I don't understand whats wrong.

change your kernel to 3.80
*edit* games that are higher then 1.50 kernel need to be on higher kernel.

Na same stupid thing happens

Try booting into your recovery menu and formatting your flash1 drive. This will help to rule out settings as the source of the problem.
