I've never tried this, but I know Retroarch, Atari cores work on the 2/3DS. Good luck. https://docs.libretro.com/guides/install-3ds2ds/@nop90 help i've tried downloading and installing every version of Handy 3DS CIA on my 2DS and tried lynxboot.img files from multiple sources but every time I try to load a rom I only get an INSERT GAME screen. What do I do? Same issue when i boot the 3dsx file through HBlauncher :/
