You don’t have to repack the iso if you’re playing on PPSSPP, if you are playing on a PSP then you need UMDGEN.

7zip can extract it.

Ok so you will need to extract the iso to patch the eboot in the systems folder, after that output it as “EBOOT.BIN”, replace the original eboot with the new one and drag the extracted iso folder into PPSSPP.

The UI version ask for the patch and the file it’s patching, I have a readme that should help on patching the file.
