I have a Raspberry Pi b+ and all works fine.
Only FinalFantasy 7 lagging the sound. Its not so dramatic but its not so cool after some houers.
The Gameplay works good, thats not lagging. Only the sound.
i try to tune the Raspberry whit the Turbo mode. But they makes no diffrent.
Can i try another sound driver or somthing?
Thank you! I change the settings in the /boot/config.txt settings and splitt the memory. My first Setting was gpu_mem=384 it works but i have Lags in sound and gameplay of the PSX Games. Now, i try to give more memory. The maximum i can give for the Raspberry Pi b+ was 448 but to much! The Games dosent start any more!Also 415 is to much, the Games become more Lags then at the beginning.
Now i try gpu_mem=408 and the sound in MetalslugX is wonderfull! Also the Gameplay, i have no Lags!
In FanalFantasy7 was the gameplay also wunderfull! The sound is much better! Not Perfect near to be perfect:)
I try to tweak the retroarch.cfg now. Maybe i can get the maximum out!
Here My config:(/boot/config.txt)
