Domino089 from RHDN told me that since ID 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. Please use Hakchi directly, do not use SFROM Tool for testing.
Earthworm Jim 2
Weird sounds replace the accordion music in the Nintendo logo. Jim doesn't yell when getting hit.
Micro Machines
Music playback issues: stutters, skips, distorts.
Plok
Annoying clicking noise as part of the music.
Space Megaforce
Bass sound in music 'pops' at high level
Super Pinball Behind the Mask
Audio popping on bass instruments.
Terminator
Audio vanishing during gameplay.
Williams Arcade's Greatest Hits
Most games lack or have garbled audio, though Sinistar is fine.
