New PSP Decrypter that plays new games on old firmware

Yoshihiro is the man. Me and my friends have a hard time trying to figure out how to play the newest games over the dated yet still great 5.00 m33-6 custom firmware for the psp. But this one needs the GEN firmware. But at least you guys could do something about it other than whine about not being able to play Gran Turismo, Final Fantasy Dissidia or Motorstorm Arctic Edge and other higher-firmware games.

Developer's note:

Hi guyz this tool is here for let you use your original game backup on CFW 5.50 gen B-2. Not all games working because some games use some fact header on prx files.

How i can use this tool ?
