TODO:
 - sound
    my guess:
     - data (samples?) in mem range 0000-$0680 ($1f00000 - $1f00680)
     - 4 chn?? ( masks $000000ff, $0000ff00, $00ff0000, $ff000000)
     - INT7 (bit 1 in IRQRQB) = sound hw 'ready' flag (checked at $56c)
     - writes to 3600000 - 3ffffff related to snd hardware

 - game doesn't work with 'demo sound' disabled
 - get rid of dirty hack in DRIVER_INIT (bug in the ARM core?)
 - is screen double buffered ?
 - flashing text in test mode

  Poizone PCB appears to be a Jamam Acorn Archimedes based system,
   Poizone was also released on the AA computer.

 - Poizone controls are checked exactly once at bootup, breaking them.
