Hello, new to this iPad emulator scene.
I’m looking for a way to change what overlay button hit boxes are bound too. I’d like the GBA left and right triggers to use the X and Y buttons on the SNES overlay for thumb use. Reaching for the top of the screen is impractical during play.
download and install ifunbox to your pc
download and unzip snes4GBA http://www.mediafire.com/download/w3rlu27tkf328tf/snes4GBA.zip
plug in your idevice into your pc then start ifunbox. Transfer snes4GBA folder to this directory Applications/Retroarch.app/overlays/
launch Retroarch, then start any GBA game then tap on little retroarch icon, you will enter gui menu go to settings>Input Options>Overlay Preset>snes4GBA>snes.cfg
go back to first page by B, B, then go down to Quit Retroarch <= it will save the changes. done
Thank you very much, exactly what I needed!
you are welcome
