Preview	Final
These preview shots were shown in issue 15 of EGM. The player select screen shows a box around both characters, in the final version, the box only appears over the character you want to select. Unless, of course, this early build had a two player mode in it. Hackers have found some unused remnants of a two player mode in the final game. But that's just pure speculation on my part.

Preview	Final
The map screen is still showing the Industrial Area level on the map screen, which was the fourth level in the arcade version. The SNES port cut this level out, making Bay Area the fourth level instead. Again, this early version might have had the Industrial Area in it before it was cut -there is some unused stuff for this missing level in the final game. But again, that's just me speculating.
