I have found a guy that will make RGB cables for pretty much every game system that is RGB capable, and he will make them to work with pretty much every RGB monitor out there.
So if anybody has always wanted to see what RGB gaming is all about, but didn't have the technical savvy to build your own RGB cables, or didn't know of any place to get custom RGB cables built, I can hook you up with the guy.
He will even do a TurboGrafx-16 RGB mod. The TurboGrafx-16 has to be altered internally to output RGB, but once it has, the resulting picture is absolutely breathtaking! I'm telling you, you have never seen colors burst off the screen like this. He charges $35 for the Turbo 16 RGB Mod. Also you can get your Turbo modded for import games at the same time for an extra 15 bucks. He will put a switch on it, that you can flip back and forth for either American or Japanesse turbo games.
As for Playstation, Super Nintendo, Genesis, Sega CD, 32X, Jaguar, Saturn and Neo Geo RGB cables, he also does those of course. Basically, what he does is build one general cable that will go to you monitor and your stereo, and then he makes ends that connect to the different systems. I think he charges 30 bucks for the first cable, and that includes the general cable and the end to one of the systems. Then future systems are typically another 15 bucks for each little connector.
For the Nintendo 64, he has supposedly learned how to modify these for RGB output. However, this is something he just learned recently, and it is a very difficult procedure, so you might want to wait until he has it perfected. This is another internal modification. With both the TurboGrafx-16 and Nintendo 64, you have to ship it to him, and then he modify's it and ships it back.
He is in Hawaii, so it can get pretty expensive to ship stuff to him. He does ship stuff out very quickly. He built me a PSone cable recently, and shipped it out to me super fast.
Also, the Playstation 1 cables also work in RGB with the PS2. So you get a 2 in 1 deal.
If anybody is interested in getting custom RGB cables made, just send me a PM and I will give you his email address. I would give his email address in this post, but he only wants to hear from people that are going to buy a cable, he gets tons of requests all the time and is super busy, and he doesn't want people asking him general RGB questions.
