I double checked and everything is perfect and yes my 32x is on lol.It still wont work. Everything powers up and the screen stays black. The tv recognizes a device but that's about it.

Hmm, perhaps one of your wires broke from inside, or isn't making good contact..

I know one test, but it's VERY long to do. Use a multimeter on continuity and test each point.

Are your wires as short as possible and of equal length? Are they twisted up or separated. Try sticking a sheet of card board between the two rows to help keep them apart.

This is the same issue I had when I used ribbon cable.

If all else fails take a sheet of foil and fold it into 3 layers. Cut it to fit in between the two rows. Solder a wire onto it and connect it to ground. Cover the foil with packaging tape and use it to separate the two rows. In effect you are creating a cheap RF shield. Don't know if it will work but you can try.

Oh and I want to see some pictures!!

edit// measure the 5V lines on the cart slot on the 32x side and make sure it isn't fluctuating.

The 32X generates a clock for the SH2 via a PLL chip that multiples 3x the Genesis CPU clock, via the cartridge slot.

That clock could be being distorted via a long cable as LE said.

A test to try...

Run a Genesis game. This won't require a clear clock to the 32X, because the 32X will never need to be "init".

I'll get some pics up tomorrow because it's apart at the moment. I want to use different wire for the connections between the 32x and genesis board. When it's back togeather, pics will be up.

Oh, I tried a genesis game but I got the same results as with the 32x.

Ok guys, It's been a while since I replied. I finally got a chance to replace the wires. I used ethernet wire and now everything is working perfect! I'm going to radioshack today to find a good power adapter to use (10V 2-2.5 amp) so I can power both units togeather. I also need to get some more wire so I can re-route the audio/video wires. Pics for now:





I ended up using a new 32x and genesis. I wanted to make sure there was no room for error this time lol. I still think my original problem with the first attempt was the wires. Oh well, I'll clean up the other 32x and put it back togeather. It should work fine.
