Pac-Man for the NES is a port of the revolutionary arcade game about eating.

Prototype Info

Unused Graphic#

An unused duplicate of Blinky's foot from the 2nd intermission, but with the red color removed.

Developer Credits#

Namco games often contain some generic copyright and/or credits text at the very beginning of their ROMs. This one contains the following text:

Additionally, the name "HIROKI AOYAGI" is loaded into RAM at address $52, in order to distinguish between soft and hard resets (the high score is retained after a soft reset).

Revisional Differences#

Yes, even a port of a game this basic has revisional differences.

Title Screen#

Japan (Famicom)	Japan (FDS)	North America (Tengen)

When Tengen localized the Famicom version for North America, they chose to overhaul the copyright text, adding the "Licensed by Nintendo of America" credit as well as replacing the unique "Namcot" logo with a simple plain text "Tengen" one. They also re-organized the lines of copyright text slightly. Unusually, Tengen did not bother to update the copyright date at all, retaining the 1984 date from the Famicom release, despite that being four years before Tengen's North American version released, and one year before the NES console itself was released in North America!

Three separate revisions were released in North America alone, each containing slight changes primarily on the title screen depending on who published them and when.

Tengen Version (Licensed)	Tengen Version (Unlicensed)	Namco Version

The first Tengen release was officially licensed by Nintendo of America. However, when Tengen lost official Nintendo licensing in 1989 due to a legal dispute, they chose to re-release Pac-Man on their own. Naturally, that means all mention of Nintendo was removed from the game.

Later in 1993, the game was re-released again in North America, this time by Namco. This release altered the copyright text once again by finally updating the date, re-instating the Nintendo licensing (although no longer specifically mentioning Nintendo of America), and replacing Tengen's plain text logo with a Namco logo, based on the Namcot one that was in the original Famicom version. A small trademark symbol was also added to the game's logo.

North America (Namco)	Europe/Australia

Then the game made it over to Europe and Australia, in a version based on the 1993 North American release. It contains all the alterations that were done for that version, as well as changing the trademark symbol on the Namco logo and removing the strange glitched tile which had been hovering in the top corner of the title screen in all other versions of the game. The copyright text has also been simplified, removing the mention of Namco Hometek, Inc.

Japan (Famicom)	Namco Museum Archives

Finally, an international rerelease was made for Namcot Collection/Namco Museum Archives Vol. 1. This version appears to be based on the Japanese Rev2 version (see attract mode demo below), with the copyright information updated to refer to Bandai Namco Entertainment Inc. instead.

Attract Mode Demo#

The screen with the ghost names was also changed across the many releases of this game, although not quite as much as the title screen.

Japan (Rev0)	North America (Tengen)	North America/Europe/Australia (Namco)

The original Japanese release has a ghost name screen that is pretty accurate to the arcade original. The Tengen version is a lot more inaccurate, rendering all the ghost names yellow for whatever reason and only including the nicknames; likely since they were the most known names of the characters. The Namcot logo is also, just like in the title screen, replaced with a plain text Tengen one, although it is in white on this screen (as it was on the title screen in a prototype of the Tengen version).

The later 1993 releases by Namco modify this screen back to being accurate to the original arcade version, while also still using the international names for the ghosts. And of course, the Namco logo is reinstated, dropping the T from the Japanese version in favor of a trademark symbol.

If that wasn't enough, the Japanese release has two revisions of its own.

Rev0	Rev1, Rev2, Namco Museum Archives

Rev0 of the Japanese release features the "CHRACTER" typo. This spelling was fixed in Rev1 onwards, and is identical to the Namcot Collection/Namco Museum Archives version.

The only other change in the ROM for Rev2 is a single byte to move a block of data from RAM $0625 to $0620 for some reason. Not certain what it actually does, but it seems to be sound-related.
