Game can not be loaded - 5.00m33-4

I installed C/F 5.00m33-4 from 3.52, the install was successful, but, I'm still getting the same problem, getting homebrew games to work! I cannot do it, I put them in the correct folder but as always I just get the "game could not be started 8xxxxxx"

any ideas?

Any help is appreciated:)

If you have a PSP Slim, the homebrew you're trying to run might be fat-only because it requires the 1.50 kernal.
How many different homebrews have you tried, and which ones?

Its not a psp slim. Err, 2.80, 1.50, 3.030e-c and 3.52.

Thanks for replying. I've got Beats of Rage to work so far hahaha, the memory stick is 4gb and is formatted in FAT32.

Thanks for the reply!

Do you have the 1.50 kernal add-on?
