Games Closing On Iphone 6 Plus

[GameHiker2000]

I'm a little new to this, so let's get right to it. I am sure I have the most up-to-date version of PPSSPP and after I was able to get the games I wanted on the app through itunes, I held down the game icon and the game opens. When I press play the app closes on me. I am on JAILBROKEN device running ios 9.0.2 jailbroken by Pangu. What is going on. Is there some settings I need to tweak? The two games installed (if that helps) is Need For Speed Underground Rivals and Grand Theft Auto Chinatown
