새로나온 게임이 펌웨어 1.5에서 RUN UMD로 실행되는지 체크해주고, 패치할 수 있는 프로그램이 나왔습니다.

사용법
----------
Generic RunUMD Mod" 폴더를 /PSP/GAME에 복사한다.

메모리스틱 맨 위에 "PSP_GAME" 폴더를 만든다.
ISO 파일을 메모리스틱 맨 위에 복사한다.

같이 들어있는 Generic BOOT.BIN Patcher (PC용) 프로그램을 이용하여  해당 게임의 BOOT.BIN 또는 EBOOT.BIN파일의 패치를 실행한다. (이하 생략)

Then, place the *PATCHED* BOOT.BIN (and EBOOT.BIN if applicable)
in the /PSP_GAME/SYSDIR folder and overwrite the original files.

Now you can try to launch to launch the hacked RunUMD from the PSP.
Try to extract the files using the Button "O" and then execute the
game using the Button "X". This should extract the firmware files
extracted from the update to the "x" folder on the root of your
memory stick.

If that fails you may want to try out "x" folders from other releases
instead or even combine them all. Not all games will extract, for
example 2.6 games. You can still try to run them by using an "x" folder
from a different 2.5 game. Basically, you need to experiment with that.

Apart from that, everything's automated for you.
