I would like to increase the volume in various Capcom games. For example Marvel Super Heroes and Street Fighter Alpha 2. I find the volume a bit low and in a loud environment it can be difficult to hear.
I open up the dip switch as normal with F2 and go to the sound options... no problem and see that the volume is set at 39%.
Then I'm stuck doing sound tests! I've tried every button I can think of but all I end up doing is changing what sound test I hear. I can't get down to the volume control even though I can see it as clear as day. Does anybody know how to adjust this? Here's a screenshot:
