problems with emulator

[taker236]

I got some problems with the emulator and I hope some one can clear it for me.
I'm using the latest build of ppsspp on android, my device is an Nvidia Shield 4.3 jellybean 'dont know if that matters

1. Has anyone got def jam ffny to work on android, I was able to get Mk unchained, dissidia 012, and kingdom hearts running perfectly but not def jam, give me a black screen as soon as I boot up the game.

2. Is their anyway to make separate settings for each game 'Ex: Dissidia 012 -buffered rendering, Mk unchained - rendering mode disabled'

any help would be greatly appreciated
