Here you go. You should set YM2612/YM3438 core to the "nuked opn2" in config.

Report on test build;
Something is wrong with the music (mame or nuked) only PCM channel playing when changing ANY setting in the options menu and returning to game.
When the game changes tunes/music the bug fixes itself...

It still happens when changing the "YM2612/YM3438 core" option.
If indeed it needs a restart in emulation or tune, it should be changed to "YM2612/YM3438 core (restart)" in retroarch's fashion.
