Iphone5s in trouble

[Ezekielchen]

Hello guys, this is my first time to ask a question here , and I hope someone can come help me.
I am running ppsspp 1.0 on my iphone5s device with ios8.1.2, everything is well except CGs. I
can't watch CGs from final fantasy vii cc. But when i use my pc to run ppsspp to open the same
file, nothing goes wrong. When i tried applying the configuration to my iphone, i encountered the
same problem. I am not sure where the problem lies, so can anybody help me with this issue? Thx
a lot!!
