The NES Pac-Man Championship Edition was originally a demake port by Japanese homebrew developer coke774. When Namco got ahold of it for the officially-licensed Namcot Collection (and Namco Museum Archives Vol. 1), development was shifted to M2, who altered a number of aspects from coke774's original. The initial homebrew version was never released to the public, though a handful of emulator-recorded screenshots and videos have surfaced, giving an incomplete look at the alterations M2 made.
