Warp Warp memory map (preliminary)

  Memory Map figured out by Chris Hardy (chrish@kcbbs.gen.nz)
  Initial Driver code by Mirko


0000-37FF ROM		Code
4800-4FFF ROM		Graphics rom which must be included in memory space

memory mapped ports:

read:

All Read ports only use bit 0

C000      Coin slot 2
C001      ???
C002      Start P1
C003      Start P2
C004      Fire
C005      Test Mode
C006      ???
C007      Coin Slot 2
C010      Joystick (read like an analog one, but it's digital)
          0->23 = DOWN
          24->63 = UP
          64->111 = LEFT
          112->167 = RIGHT
          168->255 = NEUTRAL
C020-C027 Dipswitch 1->8 in bit 0

write:
c000-c001 bullet x/y pos
C002      Sound
C003      WatchDog reset
C010      Music 1
C020      Music 2
c030-c032 lamps
c034      coin lock out
c035      coin counter
c036      IRQ enable _and_ bullet enable (both on bit 0) (currently ignored)
C037      flip screen (currently ignored)
