I'm trying to find a Mame emulator that will play Arcade Tetris on my 3DS (older version). I know about Retroarch which is difficult to install and is beyond my scope of understanding. I also know about MarcaDS which is just as difficult to install. I have a R43DS card, and Homebrew Launcher, running 10.3. I am having loads of trouble trying to install Retroarch which is possibly due the TubeHax exploit being shut down. So I am trying to find another way if possible to install Mame Emulator. Has anybody got ideas how I can go about this?
