Hardware Which Wiikey (V1) Firmware has the GC Audio Fix working?

[rhyguy]

I get laggy audio in Super mario sunshine (need to switch to mono sound), and i read that the wiikey audio fix broke in one of the latest versions.

Which version will i need to have the audio fix?

Also, since downgrading will stop SSBB from working, is there anyway i can get it to work after downgrading (and any other games that wont work)

Edit: After googling (should haave done it first), i found that 1.9b was the last FW with audio fix and 6X disc reading
Is there a way i can SMG/SSBB working if i downgrade (preferably with the disc channel, but gecko is ok)

mario sunshine has no benefit of the audio fix because it doesnt use streaming audio.

really? what else might cause audio stutters in stereo/surround sound?
