Street Fighter EX 2 - Arika/Capcom 1998 (repair log)

Game was working, sound effects were there but music was absent (in fact Q-Sound was missing).
I first swapped the CPU board with a known working one and problem followed the romboard.
It didn't take long before I noticed one tiny SMD part had been ripped off the romboard near the Q-Sound chip after a shock. Comparing with an other romboard I learned it was simply a 10k resistor bringing the clock signal to the Q-Sound chip from the nearby crystal.
I installed a new one and Q-sound was fully back.

Game fixed.
