You can find it here, SIGNED PSCRYPTER 2.0 download on FileTrip.net - FileTrip but i havent been able to get it to work yet. Ive tried a few different emulators and a few different games but they all dont work. Maybe its my PSP but thought i would share it for you guys to try.
After that worked like turd for me, i spent time on googling some more and i found this wololo.net/talk • View topic - Best PSP Tutorials EVER!!! the one that says to sign homebrew worked like a beast.
