Ms. Pac-Man Collection

A console beloved by the generational gap between Millenials and Gen Z. This Plug & Play console also introduced some members of Generation Z to the game Mappy.

Debug Mode#

On the opening screen, hold Up, press and hold A, release Up and press Down to enter Debug Mode.

Hardware Test Mode#

A hardware test for the controller. There are also graphics and sound effects from Ms. Pac-Man present on the menu.

Save Data Test#

A fake data save test.

Color Test Mode#

A color test for the TV.

Music Test Mode#

A music/sound test from all games. Each track's pitch can be altered by twisting the joystick. The music for Pac-Man is also featured here, despite the game not being included. Each of the games included also feature music and sounds (Nearly their ENTIRE sound sets! Even the IDs match the originals!) that were originally used in the arcade versions, but not this one, mainly due to simplified/unsupported/removed features.

Game Color Test#

A game color test that contains the ghosts from Pac-Man. They have colors that fade away. If you keep pressing A the colors will change to green, yellow, blue, magenta, and cyan, respectively.

Leftover Pac-Man Game#

Leftover code for Pac-Man exists in the rom. The game is surprisingly complete, but is slightly different from the GameKey versions released later on. To access this game, use the MAME cheat below, then select Ms. Pac-Man.

  <cheat desc="Play Pac-Man">
    <script state="run">
      <action>maincpu.ppw@003C=0000</action>
      <action condition="(maincpu.ppd@0E48==0007D117)">maincpu.ppd@0E48=00065E5A</action>
      <action condition="(maincpu.ppd@0E4E==0007D2F3 and maincpu.ppw@0003==0000)">maincpu.ppd@0E4E=00065F5F</action>
    </script>
  </cheat>

Leftover	GameKey Version

The leftover version's title screen uses the Namco logo graphic instead of plain text, similar to Puckman's title screen. Otherwise, the gameplay is identical to the GameKey version.

Revisional Differences#

Revision 1	Revision 2	Revision 3	Revision 4

Ms. Pac-Man Collection was one of, if not the most popular plug & play ever released (before that *other* one came out, anyway). Because of this, many revisions and alternate versions of it were produced. Here are the differences between versions:

• Revision 2 - The ability to save high scores was added. The menu layout was also changed, mainly to add an "Erase High Scores" option. This model can be differentiated from Revision 1 by a "Twist Control Steering" sticker on the back, which the original did not have.
• Revision 3 - A rare model, only sold through QVC (as evidenced by its atrociously tacky QVC menu border). Includes two extra games - New Rally-X and Bosconian. This model is silver around the area of the joystick, while the previous variants were completely blue.
• Wireless Ms. Pac-Man Collection (Revision 4) - Identical to Revision 3 (with its two additional games), but the QVC logos were removed, and the casing is completely different.

GameKey Version#

No Cartridge	Cartridge #1	Cartridge #2	Cartridge #3

Based on Revision 2, this system included a cartridge slot allowing for additional games. Three different cartridges were released:

• #1 - includes Pac-Man, Bosconian and Rally-X.
• #2 - includes Dig Dug and New Rally-X.
• #3 - redundantly includes Pac-Man and Bosconian.

All of the Gamekeys feature a similar debug mode to the standard plug & play. On the #2 cartridge, Dig Dug's music and sound effects seem to be different from the game.

Dig Dug Music Test Sounds#

NM Lockout#

In the GameKey version, a test is made to make sure its running on their branded hardware. In this case, it does a check to see if it is running on an NM unit. If the check fails, an error message will appear, which is also the same for every GameKey. This can also sometimes be done by messing with the cartridge on startup.
