/* 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
