When I start a game like Aliens Vs Predator with final Burn you can hear a nasty sound as soon as it starts.
This happens on most CPS2 and neo geo games only
Is there any fix for this or options I should change.
I had the same issue, but only when using 32 bit build. The mame 0139 ended up working for probably 95% of the games I had fba selected for. It does need a quick remap for the buttons to be correct for most of those Capcom games.
