Because of the self-made system, the EBOOT of PSP can run on PSP without signature.

Many games EBOOT cracked by China can be unsigned.

Running on PS3 requires EBOOT signature, so you will be prompted to sign it.

There are two solutions: download the original picture, but China doesn't have the original picture at all, so you can only sign EBOOT.

The PSP2PS3_v2. 1.2_CEX I use supports automatic signature EBOOT, so the landlord can try it.
