We here at 1UP Retro have been asked incessantly about getting a multi-cart for the SNES.
After several attempts at making one that was stable, we decided to not put any more time
Our alternative is the Super UFO Pro 8.
This SD card (not included) reading cartridge is very versatile and can play almost EVERY SNES game.
There are a few issues with games like Pilotwings and Starfox, but there are a few work arounds.
(We will get to that in a video.)
