3.03OE-C Homebrew issue

ive just installed 3.03OE-C and none of my homebrew applications are loading. It says 'game cannot be started.file corrupt'

any ideas please?

also is there a way to get rid of the empty icons on my memory card so that i just have my emulators and other apps. eg i have like a gap of a folder inbetween each program.

thanks

put you homebrew files in the folder called GAME150 if this dosnt work try changing the kernal to 1.50

Ok, turn off your PSP, now hold R and turn it on, you are now in recovery mode, go to configuration and toggle your kernel to 1.5
