Weird PSP Corrupt Data problem HELP!

Hello all,

I am new to the world of hacked PSP's and I want to try out the N64 Emu as well as the Commadore 64 emulator, but when I download and copy it into my PSP/GAME folder and then try it out I get two icons...one is the Emu and the other is a "Corrupt Data" icon. I have 3.71 M33-2.

When we upgraded my buddies to 3.90 M33-3 we still got the same problem...I have copied both folders, 1 folder, renamed, etc...and with no avail it always gives me the corrupt data info. When I try to run the emu it crashes, goes back to home screen and says "this game cannot be run."


Help a n00b out?
