Tafoid:
In 0.112u4, all the drivers which use the NES sound (nes_apu) came up with an error when started:
-----------------------------------------------------
Exception at EIP=01216E0F: INTEGER DIVIDE BY ZERO
-----------------------------------------------------
EAX=00000001 EBX=0DE0B6B3 ECX=00000000 EDX=00000000
ESI=00000000 EDI=03D54230 EBP=0022F6F8 ESP=0022F6D8

This included all games in playch10.c, punchout.c and vsnes.c. Once this crash was fixed in 0.113 (old bug was nes0112u4red which for some reason didn't get transferred over to this new system) according to whatsnew.txt, the sound regression can first be heard.

I'm not sure if the changes in 0.112u4 or 0.113 are what caused it (opting for earlier), however. There were some major sound changes happening across the board around that time.

Since the original report, there are newer drivers which are also effected such as cham24.c and multigam.c

Sounds like MESS bug 438: http://bugzilla.mess.org/show_bug.cgi?id=438

The time frame is a lot earlier on that though.
