OK I Have found another working exploit with % on the 1.50 PSP
By making a file out of the _DEL_00000000000037622855 and doing my research this should be close.
Due to your PSP will not let you have _ at the start of a file so by making a exploit that doe's have _ at the start this is what i came up with to launch the file
As you can see it won't say corrupt data on the launcher not the game if you change the start of this %_;=GAME%_.PBP to this _;=GAME_.PBP you will not beable to see or luanch your game.
I am doing more FAT MS research and soon enough when i find a editor that doesn't change all the game/corrupt it then i will put both my modified folder's and eboot's toghether.
