This is a sub-page of Proto:Dr. Mario (NES).
The April 27, 1990 prototype of Dr. Mario is very close to the final, but still has a few cosmetic differences.
| To do:
- Document the rest of the graphical changes.
- Pick apart the program code to see if anything else is different.

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.

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.
Graphical Differences
- The Red Virus still has its nostril placement from the PlayChoice-10 build.
- The Yellow Virus' mouth is slightly shorter:
