Joe & Mac is series I am very familiar with. I have fond memories of playing it on SNES and arcade, but had no idea it made it to the NES as well. I don’t know for sure, and I am too lazy to look it up, but it sure looks like this is just an NES port of the SNES version of Joe & Mac.
In the context of a NES game, this is great. The game has good music, gameplay and graphics. Problems is it’s not worth playing today because you can just as easily play the SNES version which is better in every way (and two player).
