Domino089 told me that since ID 10EF (EF10 in hakchi) has fixed sound issues before, then we were wondering if some of you might test a few games to see if the ID fixes some of the sound issues. Hopefully this ID (or another yet to be discovered one) becomes the magical ID that fixes sound issues, like 1068 was for games with graphics issues.
If you are not familiar with the sound issues for the following games, then please try them without the ID first so you can identify the problems, and then use the ID and check if the sound is better or fixed.
Earthworm Jim 2
Weird sounds replace the accordion music in the Nintendo logo. Jim doesn't yell when getting hit.
Music playback issues: stutters, skips, distorts.
Annoying clicking noise as part of the music.
Bass sound in music 'pops' at high level
Super Pinball Behind the Mask
Audio popping on bass instruments.
Audio vanishing during gameplay.
Williams Arcade's Greatest Hits
Most games lack or have garbled audio, though Sinistar is fine.
