This page sucks. If you could make it suck less, that would be awesome. Specifically: Generally poor image quality. Does some of this information even need to be here?

Mickey Mania 7 is another one of those unlicensed NES ports of 16-bit games that adds a random number at the end of the game's name for whatever reason. While it's unsurprisingly missing a lot of content, what's there is surprisingly faithful to the SNES original.

To do: More unused graphics. The CHR bank with the JY logo contains another unknown logo with no associated tilemaps. A tilemap with no associated CHR data. A standalone level viewer, which can be re-enabled via hacking.

Hidden JY Logo

Press Up, Up, Up, Up, Down, Down, Down, Down, Left, Left, Right, Right on the title screen. This version of the logo can also be found in Contra Spirits. The animation of Mickey and Pluto will continue to play over the logo. The only way out of it is to reset the game. This code does not change for China Rabbit Baby.

Level Select

Press A + B + Select on the title screen. Up and Down change the level, and Start enters it (warning: Some levels will cause the game to crash when the player finishes or load these levels).

Unused Levels

Although not accessible within the level select, there are two unused levels in the game, both based on The Mad Doctor level from the original game. They have no music or enemies. Freezing the RAM address 000326 to a specific value will allow access to them.

Elevator

Value: 06

Based on the elevator ride from the original game, however the elevator does not move. Collision and screen scrolling appear to be broken - you can jump onto the top of the elevator and proceed to jump further upwards, causing the screen to scroll down, revealing an uncollectable marble.

Potion Room

Value: 07

Based on the potion-concoction room that precedes the boss in the original game. A singular marble is present in the entrance corridor. None of the apparatus for making the potion (levers, beaker, burner, etc.) are present, but the level geometry has full proper collision. Due to the door also being absent, you can walk past where it would be, but the screen stops before the point where the boss room would load in the original.

Bug Levels

Value 000326, code 80 to 89/8a to 8d. Certain bug levels are accessible by using the code. Completing them may result in the game crashing.

Unused Sounds

Intended for the pencil animation.

Unused steam whistle sound.

Unused Graphics

Steamboat Willie

An unused sprite of Steamboat Willie for a pencil transition. The pencil transitions in this port only ever use the The Mad Doctor Mickey sprite. None of the other stages' pencil transitions are present. Use Value:000074 Code:6c to re-enable this sprite.

Another unused sprite of Steamboat Willie.

Skeleton Spider

An unused sprite of the Skeleton Spider.

Apple

An unused sprite of the apple.

Barrel

An unused sprite of the barrel.

Error Style Of Number

The upper number can be changed to another style, but it's not clear how to do this.

Version Differences

This page or section needs more images. There's a whole lotta words here, but not enough pictures. Please fix this.

Many games released by JY Company were available in at least two different versions, either hardcoded or selectable via internal DIP switches. Mickey Mania 7 has an alternate hardcoded version called China Rabbit Baby, which changes the title screen and Mickey sprites, as well as the cutscene animations, to a poorly-recolored Buster Bunny, using his sprites from Tiny Toon Adventures: Buster Busts Loose!.

Code/Data Leftovers

Please elaborate. Having more detail is always a good thing. Specifically: What kinds of code/data? Also, comparison of the Contra Spirits assets.

Although the debug menu seen in a few of Ei-How Yang's other games is not present here, there is a lot of leftover code/data from development, along with some early ROM banks from Contra Spirits for some odd reason.
