    TODO:
        - The display list pointer setting in the graphics chip is not understood. Currently
          it has to be changed manually. (BIOS = 0x200000, PPP bootup = 0x1D0800, ingame = 0x0000, 0x8000 & 0x10000)

        - Keyboardmania 3rd mix is missing some graphics in the ingame. Most notably the backgrounds.
          The display list objects seem to be there, but the address is wrong (0x14c400, instead of the correct address)

        - The external Yamaha MIDI sound board is not emulated (no keyboard sounds).
