Mysterious Stones memory map (preliminary)
driver by Nicola Salmoria
MAIN BOARD:
0000-0fff RAM
1000-13ff Video RAM
1400-17ff Attribute RAM
1800-19ff Background video RAM #1
1a00-1bff Background attribute RAM #1
1c00-1fff probably scratchpad RAM, contains a copy of the background without objects
4000-ffff ROM
read
2000 IN0
bit 7 = coin 2 (must also cause a NMI)
bit 6 = coin 1 (must also cause a NMI)
bit 0-5 = player 1 controls
2010 IN1
bit 7 = start 2
bit 6 = start 1
bit 0-5 = player 2 controls (cocktail only)
2020 DSW1
bit 3-7 = probably unused
bit 2 = ?
bit 1 = ?
bit 0 = lives
2030 DSW2
bit 7 = vblank
bit 6 = coctail/upright (0 = upright)
bit 4-5 = probably unused
bit 0-3 = coins per play
write
0780-07df sprites
2000 Tile RAM bank select?
2010 Commands for the sound CPU?
2020 background scroll
2030 ?
2040 ?
2060-2077 palette
Known problems:
* Some dipswitches may not be mapped correctly.
