Galaxy S7, PPSSPP (and all other PSP Emulators), Stop Working after 1 sek.

[Salamango]

Hi i have a big Problem. I Bought a Bluetooth Controller and start installing all Emulators on my S7, all work perfekly exept the PSP Emulators... Always when i load a game i see 1 sec of the loading screen from the game (i try a few) and then the Apps close and i get the message that it stops Working...

Maybe i make some misstakes? I try a few settings but all i try make the same error. Did i need to download something else? I just wanna play my PSP games without carryning my PSP all the way... Some body have a tip for me? Maybe Root my phone helps?
