Some time ago you may remember I explained here a bug I had discovered in the official NES port of Pac-Man. When you get very far into the game, starting at the 8th Key level, the ghosts spend a long period of time at the start of each level just circling around their home corners of the board. I recorded video of it happening here (30 seconds):
Well I was just notified this morning by a comment on that video, with the handle kirkbradfordmyers7196, that this happens because a table of ghost scatter times in the code is too short, so it reads data from an unrelated source which indicates a long period of time, much longer than the scatter phase is supposed to last.
kirkbradfordmyers mentioned that they’re working on a romhack that provides a fix for this bug, and others that exist in the code, and hopes to get the game much closer to the arcade. We wish them luck, and hope they’ll come back and tell us about their work when it’s done.
