The VG Resource

I found out that Ms. Pac-Man, Jr. Pac-Man, and Baby Pac-Man are replaced by Pac-Mom, Pac-Boy and Pac-Sis respectively in few games.

Here's the list of games:

Pac-Land (Pac-Mom and Pac-Sis)
Pac-In-Time (Pac-Mom, Pac-Boy and Pac-Sis in opening and ending cutscenes)
Pac-Attack (Pac-Mom and Pac-Sis in records screen)

I want to rip sprites of New Pac-Man family! There's a way to extract files from the rom games above?
