There are two main model versions of the Sega Saturn, plus multiple motherboard revisions. Luckily, all can use the same RGB SCART cable! Please scroll down for more information:
The Sega Saturn requires no modification to get RGB output, just an RGB SCART cable. That being said, in order for the cable to be compatible with all displays, there must be a 470 ohm resistor and 220uF capacitor on the csync line of each cable! As an FYI, all cables from both sellers include the correct components.

There were two models of the Saturn released, each one having different motherboard revisions. The best way to tell the difference in models is the oval vs. round buttons and the “Sega” logo on the front (as shown in the picture below). Please click on the picture if you’d like a more detailed explanation, as well as some comparison pictures:
– If you have trouble with your existing RGB SCART cable, try adding a 220uF capacitor and a 470ohm resistor to the sync line on your RGB SCART cable. Alternatively, you can order a cable that uses luma as sync, but that might have compatibility issues with some setups.
– If you’re looking to buy a Saturn, I’ve consistantly had better luck with Model 1 Saturns (all US NTSC, I haven’t tested PAL or NTSC-J), but I’ve only tried about a dozen. If you’re a die-hard Saturn fan, I suggest researching further to find out which motherboard revision of each region (NTSC or PAL) has the best video output for your solution.
– To be clear, there isn’t a “bad” version of the Saturn: All the ones I’ve tested output an excellent quality image, provided there’s nothing wrong with that individual system.

If you’re a 16-bit gamer and have never used a Saturn, I did a small review of it, but please remember the review is from the point of view of an “old fart gamer” who prefers 16-bit (and older) systems. If those style games aren’t your favorite, this isn’t for you: Saturn Review.
