I used to program in BASIC and I know a little machine language. Is there a tutorial available for editing these 2600 games so that the lives counter isn't decremented etc.? I would like to edit the original Pac-Man and MS Pac-Man for unlimited lives. My grand kids play these games and they don't get very far. They don't want to be invincible, just not run out of lives so they can see higher levels etc. Thanks for your help.
