|---|

|
Unused |
Used |
|---|---|
|
|
An unused variant of the snake-robot room. Interestingly, the moving platforms are completely straight here, probably reminiscent of an early version of the game, as this doesn't happen at any point in the game.
Wily Stage 4 (Earlier Version)#
Present in Room ID $18.
|
Early |
Final |
|---|---|
|
|
An earlier version of the boss rematch room. The final room was shrunk horizontally, the platforms were moved, and an animated background was added.
Unused Screens#
Early Title Screen#
Present in Room ID $10.
USA Version#
|
Early |
Final |
|---|---|
|
|
An unused copy of the title screen. Due to a different block being used, the "G" in "GAME START" is missing.
Japanese Version#
Early |
Early version with "MEGA MAN" tileset |
Final |
|---|---|---|
 |
 |
|
Interestingly, the Japanese version of the game contains an unused tile layout clearly meant to be for the USA logo! While it looks glitchy in the original Japanese version, applying the tile data from the USA versions of the game reveals a completed "MEGA MAN III" logo.
Unused Japanese Title Screen#
Present in Room ID $11.
|
Unused |
With "ROCKMAN" tileset |
|---|---|
|
|
Strangely, just like room ID $10, there is also a leftover title screen, but this time it is from the Japanese version! Interestingly, this screen in the Japanese version of the game is completely empty.
Early Stage Select#
Present in Room ID $14.
Early |
Used |
In-Game |
|---|---|---|
 |
 |
 |
An unused earlier version of the Stage Select screen. It seems as though this early version would have used pre-made tileset blocks for each Robot Master's name, similar to how Mega Man 2 handles it.
Wily Cutscene Screen 1 (Early Version)#
Present in Room ID $05.
|
Early |
Final |
|---|---|
|
|
An early version of the Dr. Wily takeoff scene still exists in the ROM. The city seen here is a stark contrast to the emptiness of the final version. Notice also that the early version has a large black box at the bottom, presumably for dialogue.
To see this layout in-game, use Game Genie code EAXAAAAA ELXAPAOL before the scene begins.
Wily Cutscene Screen 2 (Early Version)#
Present in Room ID $06.
|
Early |
Final |
|---|---|
|
|
This starry background with the moon was replaced with a simpler starfield in the final version. Probably done because Wily flies to the left during this scene, and they wanted the background to scroll.
To see this layout in-game, use Game Genie code AGXAAAAA ELXAPAOL before the scene begins.
