I bought this for my Retron 5 mostly because of nostalgia. I have the Snes version which to me is better. The sound on this port is garbled. The graphics are okay. Close enough to the original for being on the Genesis. The only issue i came across was with the 6 button Hyperkin controller. It kept selecting things in menus and freaking out. When I plugged in an official controller it worked. All in all a decent port.
