Crisis Core Final Fantasy VII

[iamreverie]

This just happened the other day. I was perfectly playing the game until a friend of mine changed the PSP model to PSP-2000/3000 in System Settings. I've tried reverting the settings to its default values but still ended up with no luck.

I even tried re-installing the emulator and importing a fresh copy of the ISO. I also tried to follow the "successful" and "best" settings others have posted ending up with the same result.

It was force closing when the game is about to start. Loading the state, loading a save file or even going for "New Game" does nothing.

Device used: Zenfone 5

Can anyone give me hand? I really wanted to finish this one.
Thanks.
