[datoika999]

So I have Samsung galaxy s5 mini and i have some problems with emulating in GC emu( dolphin ).

I have adreno 305
So there are those problems!

1.Low FPS
2.Object errors ingame
3.Sound problems

So about low fps idk if its ram or cpu fault?

For example i tried to emulate sonic adventure dx and sonic had black face and ingame when faced chaos 0 sonic object went underground!
And also in legens of zelda whole face of guy object stretch and looks very disturbing!

And about sounds cuz of low fps and gaming they go like beep.beep.beep

Help please!
