Running PSP ISO Help

Ok I'm going to sell my psp to my friend and he asked if I can put Monster Hunters Freedom Unite on it.I have the .iso, and have it under ms0:/ISO/mhfu.iso and cant get it to show up in the xmb.I'm running 5.50 Gen-d3.Any help would be appreciated. If any info is needed just ask.

You look under "Game" on the xmb

::)It should be there where he said. :PBut if it's not showing up at all, then I don't know what's wrong with it.

Does anything show up? "Corrupt Data" or anything.
