Summary MESS-specific 05049: megadriv [sor2]: Some of the sound effects are off.
Description Some of the sound effects are wrong compared to the console/cartridge. Several emulators do it correctly, like Kega and genplus-gx. genplus-gx source may be useful in this case, since it shares cores with MESS/MAME. I'm assuming it is the FM chip, but it can of course be something else.

The attached recordings contain two examples. One is the selection sound when choosing a character, other is the sound when you (Axel in this case) punches in the air. Kega sounds more like the real thing. I didn't bother recording it on my real Megadrive, sorry about that, I'm lazy sometimes. :) | did doublecheck it though, and you'll just have to trust me that Kega sounds more accurate.
Steps To Reproduce Play the game and keep your ears open.

I've seen it mentioned before that this is something to do with the way MAME resamples the final output, rather than the chip emulations themselves, making it sound less harsh. I confess I have never studied the MAME sound code at all tho, so that could be complete nonsense :-)

Is MT #5049 fixed? MAME r29759 and whatsnew-0154.txt says yes!
