/* Stephh's notes :
- Bit 7 of "system inputs" seems to freeze the inputs (and skip parts of code)
when it is active :
* at start, all inputs are read
* when pressed for the 1st time, the inputs are NOT read and some code is skipped
* when pressed for the 2nd time, the inputs are read and NO code is skipped
Here are the routines where this bit is involved :
* "initialization" at 0x000320
* test at 0x00014e
- Bit 7 of "misc inputs" freezes the game (code at 0x001570). VBLANK ?
- 0xc00025 is read and written (code at 0x001724) but its effect is unknown
- 0xc00031 is read and written (code at 0x001a58) but its effect is unknown
