Sei PSP Tool - Automatic Homebrew Program for 1.5 is the way to go. K-xploit was good 2 days ago. But now with Sei PSP you can create the dual eboot.pbp files in proper directories and with proper naming to mask all 'corrupt data' icons.
THis program even lets you specify a number of other items such as your own custom icon for the app when you 'generate'.
K-xploit will no doubt have these features in the future (if it doesn't die out as the dominant 1.5 'homebrew' tool.)
I RECOMMEND TO EVERYONE, TRY
Sei PSP Tool YOU WILL BE HOOKED!!!
