Any RGB bypass for the version 1 of Super NES?
I see RGB bypass chips for the minis, but anything for the first one? It's RGB looks like composite.
This should be a priority in the mod community, god dammit!

Re: Any RGB bypass for the version 1 of Super NES?
You could use the same boards if you want (probably), but the blur/smearing you are seeing has nothing to do with that AFAIK.

Check out this nice doc on the issue:

Re: Any RGB bypass for the version 1 of Super NES?
Are you talking about the original SNES?
They put out excellent RGB with no mods needed. I always had my Super Famicom connect via RGB and later my American SNES.
If you find that RGB looks like composite video, it is likely an issue with the wrong cable choice. There were official SNES scart cables that were not wired for RGB. If you used them to connect a SNES via a Scart port, you got composite video or svideo.

Re: Any RGB bypass for the version 1 of Super NES?
The 2 chip SNES does not have a RGB bypass available. It is known for being more blurry than the 1CHIP and Mini. Many people consider the 1CHIP to be an official clone console, technically it is.

Not correct. Borti has instructions on his github. Pretty sure Voultars board would work as well, with proper modification.Mobiusstriptech wrote:The 2 chip SNES does not have a RGB bypass available.

Again. 2 chip SNES doesn't have a bypass. Borti lists an untested potential bypass for 3 chip and the 1CHIP bypass.Harrumph wrote:Not correct. Borti has instructions on his github.

Re: Any RGB bypass for the version 1 of Super NES?
2-chip = 3-chip. They are one and the same. It only means the cpu and ppus are not integrated into one chip, in contrast to the 1-chip.
In other words, ANY SNES that is not a 1-chip is a 2/3-chip (=has separately one cpu and two ppus).
Edit: and they are tested for a few models, including shvc-cpu-01 which is the launch model, check the links.

Re: Any RGB bypass for the version 1 of Super NES?
Honestly never heard of anyone refer to a 2 chip as anything other than a 2 chip. I saw the models and recognized at least one as a PAL console so I incorrectly assumed that it must be a PAL thing. My apologies. First I have ever heard of a bypass for the non-1CHIP.Harrumph wrote:2-chip = 3-chip. They are one and the same.

Re: Any RGB bypass for the version 1 of Super NES?
IIRC borti's bypass method on 2/3 chip consoles will get rid of some noise on the video output but it will not increase sharpness at all, which is the OP's primary concern. As far as a mod for improving sharpness, there have been attempts, the first (that I know of) from this Japanese person:
http://vaot.mydns.jp/fc/sfc_sharp2.htm
As you can see the mod looks quite messy and complicated. The resulting image is a noticeable improvement in terms of sharpness but still not quite at the level of a 1CHIP. Borti also turned it into a PCB:
He never publicly shared this design with his reasons being:
"I designed this PCB but never published it. I got weird side effects like massive jailbars on certain situations and a noisy composite video image."
Here's another attempt on a SNS-CPU-RGB-01 (the first one being a SHVC-CPU-01):

Re: Any RGB bypass for the version 1 of Super NES?
Yes you are right, worth clarifying for the OP. Also, if he happens to have an APU model SNES, he should try Voultars fix as detailed by FBX here:unmaker wrote:IIRC borti's bypass method on 2/3 chip consoles will get rid of some noise on the video output but it will not increase sharpness at all, which is the OP's primary concern.

Re: Any RGB bypass for the version 1 of Super NES?
Only RGB bypass available are for the 1CHIP consoles, the mini is a 1CHIP console.
That claim was originally made by byuu quite a long time ago, he has since had more time to look into the SNES and basically came out and said that what he said about the 1CHIP SNES being a clone was wrong.Mobiusstriptech wrote:The 2 chip SNES does not have a RGB bypass available.

Re: Any RGB bypass for the version 1 of Super NES?
Really weird how no one has fixed this issue. There's like a zillion of these out there. Just begging to get a clear picture.
You know, not the same thing, but on the SNES topic....when I found out how the JP and EU Super Famicom and Super NES looked...I was like, "god damn, my SNES is ugly!".
One of the tip top systems, and it looks like....god, I don't know what I'd compare to to. Some kind of unfinished toy design. Like, it needs wheels or something.
Well, my favorite two systems are the SNES and the PS2, and the PS2 looks like a piece of computer equipment from the late 90s. And there is no good looking version of the PS2.
The SNES mini with RGB mod isn't bad looking, and has a phenomenal picture.
But I wouldn't mind a Japanese Super Famicom with some kind of RGB bypass. That original design is really good.

Re: Any RGB bypass for the version 1 of Super NES?
With regards to the SNES, there is just nothing much that you can do.
The picture is generated inside the S-PPU2 and leaves the chip already blurred.
Any RGB bypass or other mod can only touch-up that signal a little.
There is that Japanese guy that went medieval on the signal, applying an overdrive to speed up pixel transitions.
It's a similar technique to what they use in LCD panels to improve response time.
His work is difficult to replicate though, and is likely to have unwanted side effects.
It's a pity that the S-PPU2 test mode didn't work out.

Re: Any RGB bypass for the version 1 of Super NES?
So, basically, when it comes to the SNES, you need to choose between a blurred image (2-chip) and the occasional execution error (1-chip)?rama wrote:With regards to the SNES, there is just nothing much that you can do.

Re: Any RGB bypass for the version 1 of Super NES?
There are no issues with the 1CHIP aside from red lines running on Capcom games such as Demon's Crest, Aladdin and some minor issues with a few other games etc. Which are just what? Less than 10 games out of 1.5k?nmalinoski wrote:So, basically, when it comes to the SNES, you need to choose between a blurred image (2-chip) and the occasional execution error (1-chip)?rama wrote:With regards to the SNES, there is just nothing much that you can do.

Re: Any RGB bypass for the version 1 of Super NES?
No there aren't. Less than 10 games are affected out of 1.5k+ and they are quite minor, if the red line on Demon's Crest bothers you that's fine, but that's just removing 1 game and enjoying pretty much every other game without all the blurry mess. The second issue would also be that the 2CHIP SNES have no RGB Bypass Mod, unlike the 1CHIP, so all the improvements and fixes brought on by an RGB bypass would also not be available on the 2CHIP models.the Goat wrote:So, there are tons of issues?Lawfer wrote:There are no issues with the 1CHIP aside from red lines running on Capcom games such as Demon's Crest, Aladdin and some minor issues with a few other games etc.
Re: Any RGB bypass for the version 1 of Super NES?
What can be done for better video output is replacing PPU2 with an FPGA implementation with RGB/HDMI. It is unfortunate that VeriSNES is still closed source. It would make that possible.

Re: Any RGB bypass for the version 1 of Super NES?
The 1 chip is either compatible with all games or it isn't. The fact is, it is not compatible with 100% of the games that work flawlessly on the 2 or 3 chip SNES machines.Lawfer wrote:No there aren't.

Re: Any RGB bypass for the version 1 of Super NES?
In the grand scheme of things it doesn't really matter, the fact is out of 1.5k+ games, less than 10 games exhibit mininal issues with it, most people would take a crystal clear video out + RGB bypass capabilities over a blurrier "issue-free" Demon's Crest video output, you can clearly see this on ebay, where 1CHIP consoles sell for alot more and are in a much more demand than the 2CHIP models.the Goat wrote:The 1 chip is either compatible with all games or it isn't.

Are there any RGB bypass available for installation and modding, now? Doesn't seems like it, from the looks of it all the RGB bypass available online for sale and installation seem to be for the 1CHIP versions, what you linked is just a "proof of concept" from borti that gave him a jail bar side effect instead and as such it seems to be abondoned for now and other posters clearly said that an RGB bypass for the 2CHIP consoles will not be able to increase clarity and/or sharpness because the fuzziness/blurriness is already present from the original PPU output.Harrumph wrote:Not correct, check my post further up.
Re: Any RGB bypass for the version 1 of Super NES?
Maybe but that core has been developed without an actual SNES so its accuracy is questionable.Harrumph wrote:

Also everything from PPU 1&2 has been put together in the same file so it would have to be split first.

Yeah, post processing using all modern hardware is surely pretty effective.maxtherabbit wrote: I have a fully stock launch model and it looks pretty good through the OSSC with HDRV cables and the "reverse-LPF" feature turned on (set to about 10)
"Reverse-LPF" is the same kind of filter as that Japanese mod, done digitally.
As long as it's not too strong, side effects should be minimal
Re: Any RGB bypass for the version 1 of Super NES?
VGP sells Bortis bypass board. Also you’re confusing the bypass board (which I linked to) with his version of the japanese ”sharpness” board (which I did not link to). The bypass board does not have side effects.Lawfer wrote: Are there any RGB bypass available for installation and modding, now?

Yes the bypass board cannot correct the PPU 2 bluriness, but it may still improve output from a 2-chip as some revisions suffer from bad output quality (and to be clear, I mean quality issues that are NOT due to the ppu blur, but related to such things as board routing, encoder chip versions, failing capacitors etc).
Yes, quite astounding he never had an actual SNES! I know he is being sent consoles now for reverse engineering, so hopefully it will be improved.paulb_nl wrote:

Re: Any RGB bypass for the version 1 of Super NES?
For those talking about the "issues" with the 1Chip...there are a few games that show them. Magical Pop'n has dots that show up. For that one game, I have an old SNES still hooked up. Although, it looks great on the Super NT.
But for most games, the 1Chip with RGB is great. I would still like some sort of fix for those games. But it probably won't happen, without something kind of major, like the NES RGB.
I say someone makes it, and we can use it on the old SNES and the Mini. But there probably isn't enough demand. Most people are happy with what's out now.
