1. Create an ISO of whatever 6.20+ (6.30 & 6.31) required game.
2. Open that ISO in UMDGEN and browse to PSP_GAME/SYSDIR.
3. Extract EBOOT.BIN to a temporary folder.
4. Use PRXDecrypter to decrypt the extracted EBOOT.BIN file and rename it to EBOOT.OLD.
You need to make a folder called "ENC" in the root of your Memory Stick, and move the extracted EBOOT.BIN file there. This is also where the decrypted EBOOT.BIN will be saved
5. Download and extract the Prometheus ME631 RAR archive so you have a new EBOOT.BIN and many other prx files.
6. Add the EBOOT.OLD (the one you just decrypted), EBOOT.BIN and all those the PRX files (from the Prometheus folder) to PSP_GAME/SYSDIR in UMD GEN.
It should look something like this, if you did that correctly:
7. Save your ISO, and try it out!
