Hacking Pinball Champ for Free Play

Here are some of my notes from adding a "Free Play" option to Pinball Champ.

If you read my notes on Farfalla, this is a continuation of that effort.

ROM Layout (3 x 2532)

Not done yet, but this should be very similar to Soccer Kings.

This one will have to be done twice, to account for the regular 8-digit game ROMs, and the 7-digit game ROMs.
