As anyone manged to use (or knows a compatible version if thats the case) of PSP USB loader?

Im trying to run v0.8, i have the PSP connected to my PC, everything runs ok, i can se ISOS from the PC on PSP, but when i load ISOS, or already tried running ISO from the MemStick and it just hangs when i press X, since it happened also on loading from memory card i suppose it's something missing in the way v6.35 is exploited or the way the brew loads.

Any ideas or a valid version of the app? or any app like it?

PS: I know that the PSP is supposed to be portable, im just waiting for my future "MicroSDHC To MS Pro Duo Dual Slot Adapter" and 2x16GbMicroSD :P
