I hope I'm doing this right fellas, for years I always wanted to hack Pac-Man since the game only uses one level over and over again as we all know. I was up since 3:30am last night figuring out where the map data starts. I believe I found it, if I'm on the right track please lemme know.



When I saved what I did last night, it worked but then again I was dead tired, when I saved what I did earlier before this snapshot it didn't save. Thanks fellas for looking at my thread. ^^'

This is the Namco (U) version of Pac-Man.

I didn't bother to look too far into it, but it looks like the level data sits in RAM at 0xECEC and in ROM at 0x2CFC.

I didn't bother doing a trace to see what sort of storage format the data is in, so for that part you're on your own.

Thanks for the fellas, at first I was ashamed in asking for feedback. Glad I didn't hold back... 

Neil: I think I'm figuring out how the level is laid up, just gotta play with it a bit more.

Dan: I was guessing at first if Pacman uses the exact same level compression format as Ms Pacman, glad you cleared that up. Lately I've been getting this itch to play all type of Pac-Man games.
