With Dragon Ball - Final Bout (Japanese version) you're supposed to get the soundtest menu with holding L1+L2+R1+R2 on title screen.
It doesn't work at all with no$psx while it works just fine with Bizwhawk and the very same controller(s).
Can anyone confirm the issue ?
*EDIT*
Fixed after updating my 8BitDo Adapter For PS firmware and switching to D-Input mode !
