Yes, all of the Pac-Man hacks have their own High Score entry (Pac-Man, Hangly Man, Ms. Pac-Attack, Pac-Man Plus, Dual Pac-Man)
I just realized I didn't change two of them: Ms. Pac-Man (Fast), and Pac-Pollux The Ms. Pac-Man Fast will read the same as regular Ms. Pac-Man, and Pac-Pollux will read the same as Pac-Man.
Oh well - it's too late now
@Curt - no problem now you got me *very* curious!
