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)
