Help with choppy audio & gameplay

[gino76ph]

Hi. I'm still new to this emulators on Android. I have an Xperia Z2 phone and I have managed to transfer my games to my Xperia Z2 phone namely Street Fighter 3 Max and Tekken 6.

I noticed there is a choppiness of the audio in the SF game and the gameplay of Tekken is almost unplayable because it was too choppy and is slowed down. Are these symptoms from the ROM or my phone's capability to run them? How would i know if the .iso file is healthy or not? What settings do i need to change or alter in the PPSSPP emulator settings to make sure my games run smoothly?

Please help:-)


Thanks.
