Title Screen#

Proto	Final

Largely the same as the final version, though Dr. Mario himself is not yet present, with an oddly-positioned Blue Virus taking his place instead. There's also an extra space between "2 PLAYER" and "GAME" that was removed in subsequent versions.

Proto	Final

Graphically, the game is identical to the final version, with a few notable exceptions:

Dr. Mario still retains his chunkier design from the PlayChoice-10 build.
The Yellow Virus has been given a proper mouth (albeit not finalized yet; see below), though the 8×8 playfield tiles have not yet been modified to match.
There is no trademark (TM) symbol next to the Dr. Mario logo.

The Yellow Virus' mouth is slightly shorter:
