I made a Pacman-style game as my first game and I used the information found in The Pacman Dossier, which is where information that Nexus linked to originally came from (it's listed in its sources).
I'd recommend starting with Blinky as that ghost takes the simplest route and is easiest to understand. Then, the technique used to make the ghost find its way to where it wants to go can be used for the other ghosts too.
You can visualise the map as a single-width path with double-width walls, rather than a double-width path. This helped me immensely.
I think it it's the only game that I made (complete) so I'd be happy to discuss the innards of it, but I didn't exactly implement everything perfectly (I had no "ghost home") so don't expect too much from me

I spent most of my time with the game adding features to learn more about things, especially SFML, which is why I added a music player and volume controls, language files, etc.. Also, my code is terrible in it; the main() function is about 1700 lines long
