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.
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.

| 0x1000 | 0x17FF | ROM3 | Bank 1 |
| 0x1800 | 0x1FFF | RAM | (Mine) |
| 0x2000 | 0x27FF | ROM1 | Bank 2 |
