"Written in C, compiled with DevKitARM."
To use, flip your Switch towards your left into portrait mode and the top button on the bottom joycon {right button on the left joycon if it was in landscape mode} is the control button.
Works perfectly with the VBA-Next from RetroNX that I'm using. Use whatever GBA emu you have.
I know there was some other 1 mentioned around GBATemp with an NSP, but that didn't function on my 4.1.0 Switch.
