A PSP game coundn't be found on the disc?

[death_g11]

some games works fine on PC, but can't run on PPSSPP for Android.
I tried Persona 2, Frontier Gate Boost+ and Summon Night 5 and all I get is white icon with a "?" sign, and these messages:

Summon Night 5: Not a valid disc image.
Frontier Gate Boost+: A PSP game coundn't be found on the disc.
Persona 2: A PSP game coundn't be found on the disc.

All works fine on PC.

That would mean your disc backup(iso/cso or pbp of ps store) got corrupted either while moving from pc to android or when doing something else with it(for example there are some cso compressors on google play store which people mentioned breaking their games).

Easiest test, copy your broken game back from android device to pc and try to run that copy, pretty sure it would show same messages.
