This is a GAL16V8 that resides in the lower-right corner of Battle Garegga boards. Its precise function is not clear, but it is necessary for communication between the main and sound CPUs when playing music. Incorrect signals will at best cause the wrong music to play, and at worst hang the machine while the main processor waits indefinitely for a response from the sound CPU.

This GAL is soldered to the board and is locked, so it can not be dumped trivially.
