I just bought a 1 chip 02 for $65 on eBay. Don't search for 1 chip snes as they are always overpriced. Just browse through and look at the pics for others up for sale and check the serials. The 1 I bought had a UN319 serial so I figured it was most likely a 1 chip. Alot of ppl don't know the difference. I'm looking for a SNES console in GREAT condition, doesn't have to include anything but the console, but little to no scratches, scuffs, stickers. That's good to hear, but within those serial numbers is the 1Chip-02, not 1Chip-01 or 1Chip-03, yes, there's a 3rd one. But only the 1Chip-02 is the only one to have the color. Aug 19, 2014 - Here is my machine opened up. As you can see my serial number starts with UN1 and inside my motherboard is labeled SHVC-CPU-1. This is NOT a 1chip motherboard. 1chip boards should actually have “1chip” printed on the board. And here is another non 1-chip board from my other version 1 SNES. Jun 6, 2014 - But really, how much better could it look than a typical SNES? Of course, being obsessive and idiotic, that question kept haunting me, so I started peaking back at eBay. Any “1CHIP” listings? Nope, and if there were the seller would surely be charging appropriately. Instead, pictures of the console's serial.

RetroRGB - SNES Version Compare SNES Version Compare The SNES Mini and 1CHIP consoles output a much higher quality signal then the older SNES revisions. This page explains the differences. Please read on for more information: A Brief History of the SNES Revisions: While there is only one board revision of the SNES Mini, the original Super Nintendo / Super Famicom consoles had many different motherboard revisions and chip changes! Most of the original SNES revisions used two video chips to produce a signal and these have been nicknamed the '2-chip' versions. For whatever reason, these revisions outputted a signal that looks like it has a horizontal blur applied (some kind of low-pass filtering?) and as you can see in the picture above, it's a much blurrier image. In 1995, Nintendo released a revision to their Super Nintendo consoles that combined the system's two video chips into one chip labeled the S-CPUN.

They appropriately labeled these motherboard revisions '1CHIP'. Three total revisions were manufactured, the SNS-CPU-1CHIP-01, SNS-CPU-1CHIP-02 and SNS-CPU-1CHIP-03. The SNES Mini / SNES Jr uses the same S-CPUN chip and produces an equal or better picture as the 1CHIP models. Model Comparison: 2-Chip vs.

1CHIP: I'd like to compare some of the worst '2-chip' consoles to the best '1CHIP', a modded SNES Mini. It's an easy comparison, as all the 2-chip models have video output that's very blurry and while some are better then others, none come close to any of the consoles with the S-CPUN chip (1CHIP/Mini's). Here's a screenshot of two different '2-chip' models, next to a mini that had RGB enabled (more on that below) via the built-in S-RGB amp and the 1.2k resistors added to set the correct brightness level (click for full-sized): Sometimes side-by-side pictures don't really demonstrate things well enough, so I wanted to show an animated GIF between the SNS-CPU-GPM-02 and the Mini. Please note that I tried to line up the two pictures as perfectly as I can, down to the pixel. What you're seeing isn't the image shifting to the right, it's the filter / horizontal blur.

Also, here's the original comparison pictures I took, using a DSLR and an RGB monitor. While they don't show the differences as clearly as the screenshots above, they demonstrate what the differences look like on an RGB monitor (it's much more noticeable in person). Click on each one for full-size: For more detailed information on what exactly is happening to the 2-chip's signal, check out Chris Covell's page on the problem: 1CHIP-01 vs -02 vs -03 (no solid conclusion, needs revisiting): Comparing the differences between the 1CHIP revisions has been a huge undertaking! From the time I've launched this website until now, I've tested so many 1CHIP consoles and the results between each never seem to be consistent!

I've seen two 1CHIP-01 consoles that were close in serial number (meaning probably from the same run of production) that outputted slightly different quality video. I've seen 1CHIP-02's that looked awful, 1CHIP-03's that looked phenomenal and every combination you can imagine. I can only speculate that the issues I saw were a result of age and use; Maybe some had bad capacitors? Buku Otomotif Gratis Pdf more. Maybe others had caps so bad they leaked and caused other issues on the board? Bad voltage regulator? To make matters even more confusing, I've done an 'RGB Bypass' on a few 1CHIP consoles using it's own RGB amp and the picture quality definitely improved! That's right, simply by lifting the output pins on the S-RGB chip, removing the resistors connecting the multi-out RGB pins, then connecting them together with wire and 75 Ohm resistors showed noticeable improvement on the one console I tested.
