Gaming Metal Slug XX (US) doesn't load

[Bangaio]

Okay so I ripped the ISO from UMD, and it won't load. Since I've always played older games on PSP until this one, not sure what to do. Maybe someone can point me in the right direction.

CFW: 5.00 M33-6

Change the UMD ISO MODE?

Upgrade to 5.50 GEN-D3?

Patch the eboot.bin with edecrypt or get a prepatched version.

works fine when you apply the fix mentioned above about eboot.bin
you can just grab prefixed versions also which is becoming the norm now for releases
