Philips ADS took the liberty to upgrade Ms. Pac-Man CD-i to a 256 colour pallette and even add exclusive levels to the Arcade Classics CD-i compilation

Arcade Classics was published on CD-i in 1996 and fully developed/coded/ported by Philips ADS. There were conversions on it of three Namco classics including Galaxian, Ms Pac-man and Galaga. NAMCO took special interest in this project even though they weren't directly involved with the development of the CD-i version, the quality of the Intellectual Property had to be maintained. This went as far as the packaging itself which is detailed in the below Suggestive Themes boxout. Philips ADS were given a Pac-man arcade board with the chipset for Ms Pac-man to wire up so they had everything to do a decent conversion. It wasn't a straight port however, the entire game was upgraded to a 256 colour palette and also extra levels were added courtesy of Johnny Wood and authorised by NAMCO.


The compilation was released in Europe but not in North America. It contains the games Galaxian (1979), Ms. Pac-Man (1981), and Galaga (1981). Galaxian resembles the Famicom port instead of it representing the original arcade game. Galaga is cropped into a "window" while the status (lives, score, etc.) is moved into the outer frame. Ms. Pac-Man resembles Tengen's ports of the game and even includes the extras from their ports (multiple sets of mazes, simultaneous multiplayer, etc.).
The Ms. Pac-Man port is particularly interesting, as it is a unique port of Ms. Pac-Man not found elsewhere. The conversion of Ms. Pac-Man included on the compilation is somewhat similar to Tengen's versions. The graphics are overhauled (much like the SNES/Genesis ports), the screen scrolls, and a two-player cooperative mode is included. What makes the port unique is its selection of mazes. There are four options of mazes to choose from - Arcade Levels, Battle Zones, Team Spirit and Death Traps; the latter three are exclusive to this version.
