Hi all, Recently joined the site, though I've been reading for years. Always owned a couple of PAL Saturns without incident, so never had much need to seek out advice, but on a recent trip I bought the white Japanese model I've been craving since about 1997, and a whole heap of Japan exclusive titles. Was perfectly prepared for the voltage difference, but I have since gathered there are issues with the video output also. I've seen a lot of discussion on a few pages on the internet at large but can't find a definitive answer to my problem. Figured this would be my first port of call as it's always been a helpful read in the past. Namely I cannot get RGB output from the Japanese console. I have been using a PAL RGB cable, which works fine on my home consoles, but here just gives me a composite picture. All fuzzy with colour bleed all over the place. I understand the pin out on the JPN model might be a little different, as is the voltage delivery on said pins. So I know the PAL cable won't work. I am awaiting delivery of a new cable I'm going to try, that seems to use a different Sync method, but I don't think it's going to do the job either. I've seen a few articles suggesting I need to run a new wire from the SS +9v on the motherboard, out to the correct pin on the AV output, but is really my last resort. In short I guess my question is, is there literally no cable or device out there that will get a perfect RGB picture from a JPN Saturn to UK/PAL TV, without modding the console? Many thanks chaps and chappesses, keep up the splendid work. EDIT: This is the cable I currently have on order, if that helps. Don't suppose this is going to do the job? www.ebay.co.uk/itm/Sega-Saturn-RGB-MULTIAUDIO-CSYNC-CLEAN-SYNC-SCART-EURO-Cable-PAL-NTSC-to-YUV/172707175085?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 |

That cable you bought will work fine on all saturns, its only issue is that it will switch your tv to 16:9 mode if it supports that.

Sorry to bother you again, quick update on the newly arrived cable, and hoping you might shed some more light on it for me. I've had mixed results depending on what TV/Setup I use.
I have one small Sony LCD that displays the picture perfectly. It's perhaps slightly offset to the left but not hugely so. Works fine then, but it's the smallest TV in the house!
I have two different generation Panasonic LCDs that both display the screen waaaaay off centre, so I lose about 15% of the left side of the screen. No amount of playing with aspect ratio, Zoom or overscan settings can display the missing picture. Then I have a brand spanking new 4K Samsung that doesn't have a Scart input, but when I use an admittedly cheap scart to hdmi upscaler I get a sort of black and grey image I can just about make out some of the Saturn image on. I put that down to the scaler though since it doesn't do that on any other setup without it.
So unless I'm resigning to only ever using the tiny Sony LCD, I still don't really have a useable image. Any ideas?
Many thanks again

Never experienced or heard of this problem before.
My main problem with my JP Saturn was getting a colour image between my CRT and cables etc. Never heard of having an offset problem - you can get that sometimes with a CRT but never heard of it with an LCD.

The offset thing happens if you use pure c-sync in a SCART input, which is what that cable apparently does. C-sync is for PVMs and projectors and scalers that need a separated sync. When I try using c-sync output from my consoles I get an offcenter image as well.

Ahhh ok.
It's not a total wipe as I I have bought a better quality HDMI upscaler that has done a far better job. Works perfectly fine now! Really pleased with it. Thanks for all your input people!

Nice. Any noticeable lag? Please don't play lovely Saturn games stretched to widescreen!!!  I'm still using a CRT but I know one day I'll have to face this down. I have a 32" Sony LCD I have used with the Saturn. It has RGB SCART and delivers a very nice display but I prefer the CRT. Sexy Parodius recorded off the LCD using a Canon Powershot camera... The camera doesn't respond too well when there is a lot of black on the screen - it looks better than in this video but you get a good idea of the image quality. |

2 frames of lag and no real aspect ratio controls though you can force output to PC resolutions which the TV itself should handle as 4:3.
Has a motion adaptive deinterlacer so treats all sources as interlaced including 240p from the Saturn of course. Moving objects get smoothed out and interpolated.
another problem with this little scaler is the stutter, all input is converted to 59.94hz, since the Saturn runs slightly off the NTSC spec you will always get a little hiccup in the scrolling.
For the money though, the results are actually surprisingly decent. For you DavyK I'd stick with just your Sony LCD though (if you can't stretch to something more fancy) as that already seems to be giving reasonable results.

Looks like this chap has squared away the answers. It's obviously not up to CRT snuff but it's a convenience thing and I'm knocked aback by the results considering the cost.

Don't worry - I won't be jumping for some time! The LCD is only a backup for my CRT anyhow. |

Yepp, the scaler can output forced 4:3 resolutions, 800x600 and 1024x768, so the aspect ratio isn't really a problem. |

Looks like that's the same cable as the one I use on my Japanese Grey Saturn as well as White Saturn. I'm using RGB->HDMI converter on my PC Monitor and have no issue. |
