Here is what i have found on trying a CDI digital audio mod on my CDI 220 / 37
bad news so far all i get is static for audio : (
so far i have tested and got these systems working with no issues snes, 3do, saturn, psx , dreamcast, gamecube. I had some luck with the Jaguar still not 100%
Here is all the data and files i have for the CDI. Any help is welcome. ???
I am using a toshiba TC9231N and an external clock of 12.288 Mhz i could not find a stable clock on the cdi mother board yet...

You successfully modded the 3Do and Jaguar for S/PDIF too right? Are you going to post instructions to the Wiki?
