The adventures of the offspring of Pac-Man and Ms. Pac-Man, often snubbed for console ports and compilations (likely due to it being stuck in copyright hell).

Unused Graphics

Jr-pacman-fruits-unused.png

A whole bunch of unused toys (this game's equivalent of prior games' fruits): a skateboard, a cowboy hat (which appears twice), a rattle, a baby bottle, a pogo stick, and a pacifier. These are almost certainly leftovers from the game's earlier "Pac-Baby" (not to be confused with the separate 1982 game Baby Pac-Man) phase of development.

Jr-pacman-cat-drum-unused.png

Early (or otherwise alternate) unused graphics of the drum set andcat, which differ slightly from the ones used in-game.

Jr-pacman-circles-unused.png

Two large circles, purpose unknown.

Jr-pacman-yumyum-unused.png

An unused Yum-Yum, seemingly meant for the title screen.

CO

Part of Namco's logo. a leftover from Pac-Man (which some of this game's graphics were copied directly from).

Pacman-key.png

The key "fruit" from Pac-Man.

Jrpacmanarcade-x.png

A tiny X, used as padding in the game's graphics.

Uncompiled Code

Towards the end of the data is a portion of what seems to be source code:

MAP
LIST BABYMAP
LOAD BABYCODE
DEBUG
LOCATE SPIN,RANGE(9F20,9FFF)
LOCATE SCROLL,RANGE(9800,BFFF)
LOCATE GOVER,RANGE(9800,BFFF)
LOCATE SUBS,RANGE(9800,BFFF)
LOCATE BABYMAZE,RANGE(9800,BFFF)

LOCATE MAZE2,RANGE(A000,BFFF)
LOCATE MAZE3,RANGE(A000,BFFF)
LOCATE MAZE4,RANGE(A000,B

As with the unused toys, the multiple "BABY"-labeled codes likely relate to the game's "Pac-Baby" development phase.

Oddities

Jr-pacman-cat-outline-enabled.png

The final sprite of the cat has a thick outline around it, but it is blacked out due to the color palette used. This is what the graphic would look like with the outline enabled (colored blue).
