Identified a few more register meanings. Please see the diff for details.

Registers $210 and $211 were checked with Run and Gun and X-Men, which use the auxiliary input. These two registers gave good results, where as the other two candidates $212 and $213 did not work well, particularly for Run and Gun.

I also ran some simulations trying to identify the inputs of MULB to the auxiliary signal and the right volume. But it was pointing me to $212 and $213. As I said, these two don't work well in real games. There might have been something wrong in my setup or in the schematics. I am not sure yet. But $210 and $211 do work well in the two tested games.
