Pac-Man

The Namco Museum port of Pac-Man.

This version of the game, introduced in Namco Museum Volume 1 (1995), is notable for being perhaps the most frequently rereleased "official" version of Pac-Man from 1995 to 2005. This version of the game often featured a border based on the classic Puckman artwork surrounding it. Being based off the original's source code, it is mostly faithful to the arcade version, but a few things were altered in gameplay:

Pinky always aims exactly four spaces in front of Pac-Man when in chase mode (in the original, this became four spaces up and four spaces to the left when Pac-Man was facing up, due to a glitch). Inky's behavior has been considerably altered; he exclusively aims for Blinky's position in chase mode.

The ghosts' eyes will not travel up through the one-way paths when returning to regenerate. When a ghost is sent back to the Ghost Home to regenerate, they will always come back out instantly, even if Pac-Man lost a life on the current round. (Incidentally, this fixes a glitch that can occur in the original where Pac-Man can trap Pinky, Inky, and Clyde in the Ghost Home.). Ghosts will exit the Ghost Home to the right if their target position happens to be there. In the original game, they will only exit to the right if the behavior mode (i.e. scatter, chase, frightened) changes while they are in the Ghost Home.

If a bonus fruit appears and Pac-Man eats a ghost, the timer that controls how long the fruit stays onscreen halts with everything else. This makes it impossible for fruit to disappear while Pac-Man is eating a ghost.
