Super Retro Trio Red/Black
I have only tried the SNES port and it works fine. It even played a game that I couldn't get to work on my SNES. The best part about it is that it has an HDMI cable. The only downside I can see is the controllers at poorly made, but you can still use SNES controllers if you want.
You use the original cartridges. Some of these are what, 25 years old? So either this console has alien technology level upscaling, or... no.
