trav reported in another thread that the 309 revision board a few members had didnt have galaxian firing sound. To solve this it was mentioned that the roms were rolled back to a earlier revision

so im thinking older boards like the 4,9, 39 can they be upgraded perhaps by doing this method?

worth a thought. also my new 48 has the sound missing also but doesnt bother me.

depends if the hardware is the same, I havent seen a 39 in 1 or earlier to make a comparison.
