Interesting

Just did it.

lib/armeabi/libdefault.so - Is the PSP emulator, it's encrypted but you can obtain the unencrypted file from /dev/kmem on a rooted Android with a custom Kernel.

There's also a zpak file that has a file called "image.ps" which is the JAP ISO of Locoroco Midnight Carnival for PSP.

We could give a look to libdefault.so for anything useful

even if i don't fully understand how can you/we read a compiled binary that contains machine code (.so) i'm really curious to know what happens if you replace that image.ps with another game image,renaming it like that (see PSXperia) did you already tried?

I'm pretty positive it won't work because PSXperia checks if the gamedata matches or if it's replaced with something else. Now PSXperia has a patch around that but the way PSP isos are as data and their codes shouldn't match the kind of patch PSXperia uses. Maybe somebody else can try it for me? I have zero knowledge on recompiling PSXperia titles. I guess/bet if it worked for PSOne games it should work for PSP too BUT the code/patcher would need to get support for it.
