Head Panic
- Maybe the sprite code can be merged again, haven't checked yet.
- Nude / Bikini pics don't show in-game, even when set in test mode?

      MCM6206 is 32kx8 SRAM
      6116 is 8kx8 SRAM
      * : Board has positions for 6x standard 32 pin EPROMs but only position ESD5 is populated
          with an EPROM. In between the unpopulated positions are 2x smt pads. These are populated
          with 2x 16M SOP44 smt Mask ROMs.
      % : ROMs ESD8 and ESD9 are also 16M SOP44 smt Mask ROMs, though these are dedicated smt
          locations (i.e. no option for EPROMs at this location)
