I will start with Nintendo Nes Famicom games well you have to get a retro duo,FC-Twin Dual " recommend ", or a new version to play your games.
Yobo sales an adapter to plug into your 8-bit & you can play The Japan Famicom Imports.
Next is the Super Nintendo or better & easier is the FC-Twin.
With the Super Nintendo the only thing stopping you is the 2 plastic pieces where you insert the cart.
If you can cut them out you can play.
You can also take the lid off your system & I tried taking apart Super Nintendo systems they are a pain.
If you have a FC-Twin Dual System just take out the 4 screws in bottom unfold the lid.
Insert the game and there you go.
Now you can play both the U.S. versions & Famicom NES or Super Famicom games that may not ever been released in the U.S. or other that it is just cool to see everything in symbols instead of words.
