Hi friends, I have this problem with my retropie setup.
My raspberry pi is highly overclocked, but still almost all my fba roms play very (very) slowly, in Neo Turf Masters (A simple golf game) I can not get over 35FPS, the sound is terrible, so I did the following reasearch:
I am running the games with the retroarch core, if I change to the binary version the games run fine, but I can’t get the games in full screen, big black borders on top and bottom (and yes I have my overscan adjusted, with retroarch fills everything just right) and I just don’t know how to adjust that. Besides that I prefer using the retroarch core because of configuration options.
Another thing I found is that when I disable completely sound (audio_enabled = false) I get perfect 60FPS in all games! Please help and thank you in advance!
PD: Sorry for my english, I am from Colombia (Yes, Falcao and Shakira)
The Retroarch FBA core is terrible in the pi. I doubt you will be able to get full speed with it. Have you tried going into the Pi-fba config file and changing the aspect ratio? This way you can make the image fill the screen. I definitely recommend the binary over retroarch.
