The missing sounds are probably down to a single cause. I'll try to find some time to fix it over the weekend. I don't have much time for testing FBL releases as I'm moving away from Xbox emulation at the moment, so I'm afraid you're all effectively beta testers from now on.
That being said, penbros works fine for me and I have none of the graphics issues you mention with opwolf3.
fair enough +T+
ive rolled back to FBL 1.7 but kept the new toaplan core for the new sound for v five etc plus ive shifted penguin bros back to my other arcade emulator
so in a roundabout way everythings sorted
