Very cool. I live in Japan and see NES carts in all the second hand stores that are everywhere here. Very tempting but in the end I know I wouldn't play it. Whenever I go down a "weee let's try retro" path I lose interest after five minutes
And then I got the wireless 8bitdo controllers that can work with the original NES/SNES ports, because fuck cables (briefly tried using OG controllers and it was awful).
Now I actually play the games a decent amount, and my wife plays Tetris or Dr Mario all the time.
Now it's my travel device when I'm on holiday or having no energy left to focus on code. It's pretty convenient only because of the sdcard cartridge adapter.
Did not regret spending 50 bucks for the mods. Would heavily recommend.
