Uploading this so everyone can use psx games on their updated psp. It took a couple of hours reading and decrypting so I figured I would give you the finished product. (confusing sometimes too)
If you are using a M33 custom firmware than this has everything you need to get to 5.00 M33-4, fat or slim, with all of the popsloaders from previous versions working
This is meant as support for my PSX to PSP (ps1 games) torrent file here....
.... a lot of psx games. with seeders now
