Crazy Balloon memory map (preliminary)
0000-2fff ROM
4000-43ff RAM
4800-4bff Video RAM
5000-53ff Color RAM
I/O:
read:
00 dsw
01 joystick
02 bit 0-3 from chip PC3259 (bit 3 is the sprite/char collision detection)
bit 4-7 dsw
03 bit 0 dsw
bit 1 high score name reset
bit 2 service
bit 3 tilt
bit 4-7 from chip PC3092; coin inputs & start buttons
06-0a-0e mirror addresses for 02; address lines 2 and 3 go to the PC3256 chip
so they probably alter its output, while the dsw bits (4-7) stay the same.
write:
01 ?
02 bit 0-3 sprite code bit 4-7 sprite color
03 sprite X pos
04 sprite Y pos
05 music?? to a counter?
06 sound
bit 0 IRQ enable/acknowledge
bit 1 sound enable
bit 2 sound related (to amplifier)
bit 3 explosion (to 76477)
bit 4 breath (to 76477)
bit 5 appear (to 76477)
bit 6 sound related (to 555)
bit 7 to chip PC3259
07 to chip PC3092 (bits 0-3)
08 to chip PC3092 (bits 0-3)
bit 0 seems to be flip screen
bit 1 might enable coin input
09 to chip PC3092 (bits 0-3)
0a to chip PC3092 (bits 0-3)
0b to chip PC3092 (bits 0-3)
0c MSK (to chip PC3259)
0d CC (not used)
