I installed a XenoGC in my "spice" (i.e. orange) Japanese Gamecube last fall. Despite all the stuff you might read about disk reading problems and needing to tweak the potentiometer on the laser, etc., mine has been 100% from the start with no fiddling. (so don't bother buying a multimeter and messing with things until you've tried burning disks on at least a couple drives first, if you have problems)
I bought some bulk 8cm DVD-R, burned with imgburn on a generic laptop drive, and they've all worked great. (I made a couple coasters at first, on my desktop's worn-out Plextor. Switched to the laptop and all was good.)
Here's the link to the same disks I bought. I've almost used up my second stack now, but my collection's as complete as I want it to be.

But a warning ... installing a XenoGC, or any GCN chip, is not an easy task if you have no soldering experience. It's very fine work. I used the so-called 'short-wire' technique, and it all worked out great. But it wasn't my first time to the rodeo - first time I installed a modchip was around 2001.
Here's a link explaining the short-wire installation:

As with anything like this, research the hell out of it before you act. Good luck.
Edit: Also, if you go ahead with the mod and it's successful, then get yourself a new genuine 1019 Memory Card while you still can. $24 on amazon. You're gonna need it.
