Easy SNES/SFC YUV component video!

I did this already with a ba6594f, colours looked completely off.

Hey Drakon, So you followed the ba6594f page 15 with the exact input and output and applied a 6db gain amp on R B outputs and the colors were horrible?

What did you achieve the best results with what method? (RBGchip)

I added small transistor amps using 2n3904s on the colour lines. This made the colours the right strength, but the colour green was completely off....I hate component.

Hrm, i am still going to give it a go, im going to add trim pots where the resistors are, and see if i can fine tune something and see whats the ideal Resistance is.

I wound up having to do the same thing on the BA7230LS. It's different for every system so far.

I know the component capture device I tested it on is fine. I've used it to test component video from a genesis passed through one of those ebay component things, as well as a jrok (the ebay one has a sharper picture). Both of my purchased rgb to component boxes the colours looked fine. It's kind of disappointing that these DIY ones need adjusting for every system / tv, I think I'll stick with my ebay one.

the problem I have is I'm in for 100+ BA7230LS units, so unless I can unload em for a decent price, I'm in for the long haul.

Which box is it?

Im in the same position with the ba6594f, i see no reason why couldn't get a good picture of of this component or the BA7230LS for that matter.

Im just going to do as i mentioned build a bread board circuit and put a lot of trip pots in. hook it to a splitter that will go to 5 TV's and wire up 5 consoles ready to just be put in and mix and match between all of them till i get a nice picture on all of them.

If i can produce a picture on 5 totally different TV's side by side with different consoles im pretty sure it would work for majority of TV's out there.

Im sure more people are going to start jumping in on this as the second i read about it i had to be a part of it.

Drakon, is this the box you got ? : http://www.ebay.com/itm/Scart-RGBS-T...item35c1521283

Yup

Have you opened it to see whether it has an ASIC, rebranded IC or glue logic?

Anyone have luck with Saturn, Master System, or PS1? Not often people bother to component mod those. Especially since PS2 already does that for 99% of PS1 games worldwide.

I opened it but I didn't study it that thoroughly.

I tried the BA7230LS on the Saturn and Master System, but not the PlayStation as I don't have an RGB cable for it. The Saturn looks absolutely beautiful, but the Master System, at least if it has a Sony V7040 encoder, has dark video and slightly oversaturated colors, which means the voltage divider at the RGB inputs needs to be altered. Strangely, though, on my LCDs (Samsung SyncMaster 244T and Toshiba 26HL37), the Master System looks good (albeit very wavy on the 26HL37 and shifted WAY up on the SyncMaster 244T due to the monitor not properly supporting 240p via Component)! It only looks dark on my Electrohome 27E510 CRT TV, and it looks better if I place some 3.3Kohm pull-up resistors on the RGB lines, but there has to be a better way to make the video signal brighter (TmEE told me this could kill the RGB outputs due to excess current from the pull-up resistors).

Um I meant component modding them.
