Apparently it's a console thinger that uses standard SNES controllers, but has the ability to play both NES and SNES carts by having a second cart slot. At 50$ it's not that bad for anyone who either collects these weird hardware things or has a lot of carts and no longer has the system to play them on (cheaper than finding a snes and a nes).
Thanks to DaMadFiddler for linking me to this.
