Pac-Man 4K

This is a "new" version of Pac-Man for Atari 2600 I've been programming since about 2007, but had left in 2008, then in 2013 I resume again to try to finish. I've been trying to make it as close to the original looking at various sites on the "AI" Ghosts, game logic, etc. This version has nothing to do with the other version called pacman4k, this is a completely new version, do not use any undocumented opcode. Currently the rom is about 120 bytes free, so I'm trying to add other things.
