Stevie Goodwin Posted November 30, 2017 Share Posted November 30, 2017 (edited) Hi guys, I have an SNES launch model from 1991 with a UN10 serial number which works and turns on, but i have a problem with WWF Royal Rumble and Aladdin. They glitch on the Title Screen. I'll show you the glitch. And no the games are not the problem. I tested them in a SNS-101 Mini Jr and they are glitch free. Here is a video: SNS-001 (Glitched): http://www.youtube.com/watch?v=JjXCx3aEoBQ&t=19s SNS-101 (Fine): http://www.youtube.com/watch?v=GQC-xdUahbo Edited December 1, 2017 by Stevie Goodwin Quote Link to comment Share on other sites More sharing options...
+H454 Posted December 1, 2017 Share Posted December 1, 2017 The snes jr is at least three versions newer of the video processors. They even went from two ICs to one. One of the ic revisions may have been to fix something like this. Snes are one of the cases where older they are, the less desirable they become. I just got a jr because it was a one chip and did the rgb mod. They rgb difference between a 2 chip and a one chip is night and day. 1 Quote Link to comment Share on other sites More sharing options...

Forgive me if you've already considered this, but I would suggest cleaning the cartridge slot on the console. If it's removable, clean under it as well. Also, just look it over and see if any of the pins show corrosion or artifacts (hair, carpet fuzzies, gum, straw wrapper etc). Other than that, I would suggest the console has a failed IC, or a bad trace to the cartridge slot. Quote Link to comment Share on other sites More sharing options...
tbb033 Posted December 1, 2017 Share Posted December 1, 2017 Royal Rumble has always worked fine on my launch era Superintendo, and I must have played it for thousands of hours. Never played Aladdin. Quote Link to comment Share on other sites More sharing options...

Can i take pictures of my console taken apart? Also the issue is not random at all. Edited December 1, 2017 by Stevie Goodwin Quote Link to comment Share on other sites More sharing options...
Stevie Goodwin Posted December 2, 2017 Author Share Posted December 2, 2017 Also i need a new board Quote Link to comment Share on other sites More sharing options...
keepdreamin Posted December 2, 2017 Share Posted December 2, 2017 Just use the SNES Jr then, if it's bothering you that much. 1 Quote Link to comment Share on other sites More sharing options...
Stevie Goodwin Posted December 2, 2017 Author Share Posted December 2, 2017 Just use the SNES Jr then, if it's bothering you that much. But i don't like the Jr. It lacks S-Video and i don't like the sharper image and design. Quote Link to comment Share on other sites More sharing options...
keepdreamin Posted December 2, 2017 Share Posted December 2, 2017 huh? You don't like that it doesn't have S-video (which would give you a sharper picture), but you don't like the sharper image? ok....... 1 Quote Link to comment Share on other sites More sharing options...

I seen alot of them dead. Is there anyone who know how to do SNES PPU swaps? Quote Link to comment Share on other sites More sharing options...

Yup, hot air station. But it's totally not worth the time it takes to do it. Also, Its like $30 (retrofixes.com) for the mod kit the add RGB and s-video to a jr. If you only want s-video, its two wires to solder. Actually the same kit is $15 from console5. https://console5.com/store/nintendo-multiav-add-on-rgb-bypass-s-video-kit.html But I think It is solder your self kit.

Also the issue is not random at all. Well, Are SHVC CPU 01 SNES consoles unrealible. I seen alot of them dead. Is there anyone who know how to do SNES PPU swaps? Unfortunately, I've never done a chip swap on a SNES since they are surface mounted chips and a lot of work is required. If you have a super everdrive, there might be a program that can test chips for pass/fail. I wish I could help, but unless you're an electrical engineer, and have high end tools to solder, it might be a lost cause. I know on an original NES, solid colored screen is typically bad CPU, Black screen is bad PPU and failed ram is distorted graphics (like your example). That's not a guarantee though, there are many different ways a chip can fail. One thing I just thought of though, if you leave the system on for awhile, do any of the chips get hot to the touch? If so, it may have failed. Quote Link to comment Share on other sites More sharing options...
mobiusstriptech Posted December 5, 2017 Share Posted December 5, 2017 There are many failure points on the early Super Nintendo's. Capacitors, cart slots, PPU, 7805, random IC. In many cases repairing them is not worth it because they are so cheap to begin with. All that being said, the SNES mini only has a sharper picture through RGB, which it sounds like you are not using if your console is not modified. The composite output on the mini is on par with the early 2 chip models. Quote Link to comment Share on other sites More sharing options...
