Joe & Mac is a platform game originally released in 1991 for the arcades by Data East. It was later ported for various consoles, as the SNES and Mega Drive / Genesis. Rod_Wod sent us some screens from a version of Joe & Mac for the Mega Drive / Genesis that seems to be different from the released one (a simple port of the Arcade version).
For example the background of this boss from the magazine scan:
Looks different from the one in the final game:
Could those screens in the magazine be from a beta version, or a different / cancelled Joe & Mac? We have not finished the final game, so we are not sure. If you have finished Joe & Mac and recognize those images, please let us know!
Thanks to Rod_Wod for the contribution!
