Another update for PSP PHAT/SLIM user.
All right, all right… Liquidzigong sharing the love for PSP-1000 and PSP-2000 (non-TA088v3) owners: no more tedious ISO patching. That’s right. You’ll need to be running CFW 5.50 GEN-D3; D2 may be compatible. Try it and leave a comment below. And no, before you even ask — this will not work with Half Byte Loader or PSPgo models.
Install 5.50 Prometheus by simply copying the extracted archive directory to ms0:/PSP/GAME and running it from the XMB, like any other homebrew. The required files to run 6.20-required games will be copied to the appropriate spot and then you’re all set. Call it 5.50 Prometheus or 5.50 GEN-D4.
