Proto:Mega Man 7
This page details one or more prototype versions of Mega Man 7.
There's no build date in the ROM, but the chips on the board are labeled 94/11/11, placing it more than four months before the Japanese release date. A large chunk of content is missing or in an altered form.

Changes with Mega Man's weaponry (such as it is).
| Intro Stage|
The opening stage was heavily reworked after the Sample.
| Cloud Man|
See the changes in Cloud Man's level.
| Freeze Man|
Many cosmetic changes in this frigid landscape.
| Junk Man|
Junk Man's factory went to seed after the Sample.
| Slash Man|
Not as many changes as the other levels, but still interesting.
| Shade Man|
A barely-formed level only accessible by code.
| Spring Man|
Look at a Robot Master's stage in its infancy.
| Sprite Changes|
Many sprites have different graphics at this point.
| Sound & Music Differences|
The audible changes between versions.
Right away differences can be seen. The questionable choice of a bright blue background was changed in the final. The Sample does not contain game options or a subtitle. The shading on the logo was also changed slightly for the final.
The Sample version starts you off with the Super Adapter, Rush Coil, and a full stock of tanks. These tanks are actually infinite in supply, so you can use as many as you want.
The Sample's stage select has placeholder icons, which read 「工事中」 ("Under Construction"), for each of the boss pictures. Note that the actual boss pictures are actually finished, just not used, probably to keep the Robot Master designs a secret.
The bottom icon will take you to Slash Man's stage, as Burst Man's stage is heavily unfinished. The other four Robot Masters' stages are present in the sample, but cannot be accessed without cheats, and are even more incomplete than the other stages.
After completing every stage in the Sample version, you're taken to this screen. After that, the game resets.
Inaccessible Test Stages
Comparisions with the final version.
These stages exist, but are heavily incomplete and use temporary graphics. Only the layout is present.
In order to access them, you need a stage modifier code 7E0B73XX, where XX is the level ID. Note that in these stages the player spawns at the wrong X position, causing the warp animation to never end (and you'll get stuck). As a result, you also have to change the player's X position using the code 7E0C0601. Remember to disable it after you land on solid ground.
The palette for the stages, shown in the maps, is loaded but never used.
Level ID: 04
Level ID: 07
A few objects have been partially implemented but haven't been placed in any prototype level. Use the code 7E19CAXX, where XX is the object ID. This will change the first object on a screen.
Due to the way the code works, some object graphics may be bugged.
Object ID: 0F
The water mine found in Burst Man's stage. It's entirely complete, just not used here.
Swim Metall DX
Object ID: 1B
This might be complete, but, again, since water hasn't been implemented it's hard to say.
Object ID: 20
Very close to being finalized. His A.I. is complete, but the boss energy bar routine has not been implemented. "Defeating" Turbo Man will just make him disappear.
Burst Man's Bubble
Object ID: 25
The bubble that traps Mega Man. Fully coded.
Object ID: 26
The giant crab boss in Burst Man's stage. A.I. is preliminary: it walks forward, lays down one bubble, then walks back. This loops until Kanigance is destroyed.
Count Bomb Platform
Object ID: 27
Barely coded. Stepping on it starts the countdown, then crashes the game.
Object ID: 29
A.I. seems complete, but the Shade Man object and projectiles have no solidity. He cannot harm Mega Man or be harmed by Mega Man.
Object ID: 2A
Performs his intro animation, but that's it. He's still solid and can be damaged, so that's something.
Free Movement / Level Editor
Use the code 7E0C0224 to enable a kind of level editor. This seems to be bugged, so that code might not be the best way to access this feature. This enables debug commands on both controllers.
Pos. X and Pos. Y represents the position of the cursor on screen. Cell No. is the ID for the cell under the cursor. Hit No. seems to be collision information.
- D-Pad: Moves screen.
- A: Foreground toggle.
- B: Speeds up screen movement.
- X: Unknown; freezes the game.
- Y: Displays two screens of data.
What these numbers represent is unknown.
- D-Pad (2P): Moves cursor.
- A (2P): Set Cell No. to 0000.
- B (2P): Increases cursor speed.
- X (2P): Unknown.
- Y (2P): Changes cell that the cursor is on.
- L (2P): Increases Cell No.
- R (2P): Decreases Cell No.
An object viewer exists here, and can be accessed using the code C005B302.
The text's palette is glitched in the final, but in the Sample it's perfectly fine. The object numbers go up to 56 in the sample, and 9D in the final.
