/***************************************************************************
Championship Baseball
driver by Nicola Salmoria
TODO:
champbbj and champbb2 don't work due to protection - a custom mcu probably.
The protection involves locations a006-a007 and 6000-63ff. It pulls
addresses to routines from there.
0000-5fff ROM
7800-7fff ROM (Champion Baseball 2 only)
8000-83ff Video RAM
8400-87ff Color RAM
8800-8fff RAM
read:
a000 IN0
a040 IN1
a080 DSW
a0a0 ?
a0c0 COIN
write:
7000 8910 write
7001 8910 control
8ff0-8fff sprites
a000 ?
a060-a06f sprites
a080 command for the sound CPU
a0c0 watchdog reset???
The second CPU plays speech
