No.11599 trebor Tester Apr 11, 2015, 22:03	The Exidy driver uses the m6502. It's the same "issue" as mentioned in the Notes section here: http://mametesters.org/view.php?id=5915. Tested the Exidy games and they sound fine after the revert is applied.
No.11602 Augusto Tester Apr 12, 2015, 05:12	Mouse Trap (all sets) after of first stage the game stop without progress and has sound problems.
No.11603 AWJ Developer Apr 13, 2015, 03:02	venture plays music again after 90a6a52; can someone more familiar with these games confirm that all of them sound like they should again?
No.11621 Tafoid Administrator Apr 21, 2015, 20:50	They still do not sound correct. Testing seems to indicate it affects all games using "Exidy SFX+PSG" and "Exidy SFX+PSG+Speech" devices, including venture locally. This would include exidy.,c and victory.c as well.
No.12428 Zaghadka Tester Mar 5, 2016, 20:46	I was able to play Mouse Trap on Mame64 0.171 past the first stage without a lock up, and the sounds seem fine. Venture seems good too. I'm using Windows 10 (10586) and 64-bit MAME. Was this fixed but forgotten? I've been following this bug, and I'm not having the problems described above when running these games in 0.171.
No.12435 Tafoid Administrator Mar 6, 2016, 11:18	Yes. the change that brought about the issue was mistakenly reverted but never corrected. Time will tell if the change will return.
