I ported the gameboy advance emulator gdkGBA (originally made by gdkchan) to the nintendo switch!Unfortunately this emulator doesn't support in-game-saving (it crashes when you attempt to save!) so I added an savestate feature:Press Plus+R so save the current state and Plus+L to load it again.Simply put the rom into sd:/switch/roms/ and start the homebrew.As soon as retroarch gets updated for 5.0 this will instantly become obsolete! source (you need the sdl2-libraries from the devkit-pro pacman to build this)Known issues:The sound is a bit off.After loading a savestate the sound gets even more off for a few seconds (or until the music changes)
