|Summary||06989: champbb2j: AY-3-8910 sound is completely missing|
The AY-3-8910 sound is completely missing in clone Champion Base Ball Part-2 (Japan).
Only the DAC sound is working!
|Steps To Reproduce|
The parent set Champion Base Ball Part-2 (set 1) uses the address 0x7000 and 0x7001
to write commands to the AY-3-8910 chip, while the clone uses 0x7001 + 0x7002.
