2525Stephh's notes :
2626
2727  - Coin 2 as well as buttons 2 to 4 for each player are only read in "test mode".
28    Same issue for Dip Siwtches 0-7 and 1-2 to 1-6.
28    Same issue for Dip Switches 0-7 and 1-2 to 1-6.
2929    Some other games on the same hardware might use them.
3030  - Dip Switch 0 is stored at 0xf0ac and Dip Switch 1 is stored at 0xf0ad.
3131    However they are both read back at the same time with "ld   hl,($F0AC)" instructions.
