I'm currently studing EE at UT

If that ribbon cable works out for you I will have to find a local source to obtain it. I was using standard HD cable.

Heh, I'm not "certified" or anything like that, self taught myself, and do quite well.

HD cable, be it 40 conductor or 80 conductor UDMA, is just like that, too thin. This ribbon is slightly thicker.. Sadly it's only in "3 conductor" from the computer, but that's cause it only carries the RGB signal, the larger ribbon carries GND, H Sync, V Sync, PWR, Audio L, Audio R, etc, to the all in one chassis.

I'll use the thick ribbon for that, RGB, and the small ribbon (HD 40 conductor size), for GND and C Sync...

Good thing audio doesn't get mixed in the 32X, and actually takes place on the Genesis itself, so the audio on the Genny will go directly to the AV out.

Ideally you would want each wire individually shielded but I couldn't find anything that thin. I guess you could spiral wrap the wires with some aluminum strands and ground it but that would be alot of work. Maybe next time I will make a jig to do it for me.

Yea, then shrink wrap it.. But, if Apple didn't need to, and only had a single ferrite bead and passed FCC regulations like that, I'm fine.

Well, I finished it but apparently, there is a bad connection somewhere because the game wont boot. I'm about 95% sure it's one of the wires that goes to the 32x. I'll look it over tomorrow.

Make sure you got the RGB GND CSync lines coming from the Genesis into the correct pads on the 32X.. That's the only thing that needs to go into the 32X's video mixer.. 32X will generate it's own Composite video signal. (and Genesis mixes audio by itself)

I havn't converted those yet, they are still connected normally with the original cable while I do testing. I believe my issue is with one of the soldering points on the 32x itself.

[evildragon]

Ok. Just make sure all points are secure, you powered the 32X , and make sure no points are crossed.
