Love this game. But I can never fully get into it because of the sound bug issue. Has anyone tried to fix it? Is it even possible to do I'm no tech expert so I have no idea if it is somewhat possible to pull the files from the card, fix the bug and then put the files back on the card. Would be nice to be able to fix the problem.
If it were fixed, it would be a patched ROM (your HuCARD, and mine, will remain forever flawed) playable via emulation, flashcart, etc. (See Turbo Everdrive)
This glitch has been mentioned over the years... I am not sure if one of the tech gurus has looked into it, but they have mentioned that, in general, "seemingly simple requests" sometimes entail "massive amounts of effort", so pray with me (Order of the Rat) that the bug is relatively "easy" to diagnose and remedy.
