That's going to be a pain in most cases if its a pre-made cable. For most of those they attach the wires to the actual plug, then they toss the whole thing in a mold and fill it with the rubbery plastic so its one solid piece between all the internal pins and for the stress relief and grip. So you'd be digging out a bunch of plastic in little pieces trying to not mess up the internal connections. Then you'ce still ended up with a plug that you'll probably have to just wrap electrical tape around when you're done unless you can find a rubber cover. :(

din are a pain in the ass to attach anything to let alone get them open heh

i'm going to at least test if the rgb out will work before i buy anything and i'll report back here when done...

Well it dose not work...

I have send the rgb threw the converter and nothing so then i ran it directly with the sync into the vga and still i can't get a signal... i retested it on my only CRT tv to make sure i didn't break it and sure enough it still works fine... i just don't get why its not working.

i'm thinking it would be easier to get one of those usb read everything boxes and just have my PC upscale it.

Your monitor probably expects seperate horizontal and vertical sync.
If it really is a multisync monitor that supports 15khz interlaced signals like you claim (wii outputs 480p 31khz vga compatible signal) which is what the saturn actually spits out, you're going to have to build a simple sync seperator circuit that splits the composite sync into seperate h+v sync signals. You can wire those up to a D-Sub connector and that would be it.

Your best bet is using a european or japanese scart cable which has pretty much all the pins wired (necessary ones anyways), chopping off the scart connector, and soldering on a d-sub.

This is what I meant when I mentioned cutting the other end off. I forget that America was never blessed with RGB SCART.

I've tryed to build one of those before but the other way around(vga to composite) couldn't get that to work so i'd say its just me :P

I had a look on ebay and i think it would be easier and safer to just get an s-video cable for the Saturn(mine has the composite mod) and invest in a decent capture card that can display things in real-time.

I'd see how you think the s-video looks. Its actually pretty good on my TV. At least see while you investigate your options if you're still intent on going RGB. :)

this makes me think s-video is not rgb as i thought it would be... well anyway i can't find a single decent capture card for under $1k... most of them are these stupid little usb things with 400ms latency >.>

It isn't. S-video carries colour (all colours combined) and luminance on separate pins so it is a slight upgrade over composite which carries all the information on a single wire. RGB has the red green and blue separated and is generally known as a component signal, since the video is split into it's respective colour range and sent down individual cables or components. Hence the name. It can also be carried over SCART connectors.
