The free way is the difficult way, cause it involves "hacking" and you can brick your console
Spend $30 on a Pi... throw an emulator on it.. call it a day. My arcade machine runs 8000-9000 games with a $30 Pi.
Pi is probably the best bang for your buck youll ever get to play retro games
Yep. Friend of mine has the Pi setup and it works well. Load times are a bit slow compared to my Homebrew Wii but it does work and it's super cheap. @Coiled03 PM me if you like and I can tell you a safe place to get all the ROMs.
