Hi,
I have been interested in getting my GameCube modded for Optical audio for awhile now, but lack the experience and free time to attempt it myself. Is there anyone skilled here who might be able to perform the mods if I were to mail them my system along with monetary compensation? There may be other guides for this sort of thing, but I came across these.

Might also be interested in the GameBoy Player Audio Improvement Mod (Unconfirmed?)
