Title: Poor video quaility SD2SNES Pro
Post by: TheDrunkenBeard on June 23, 2019, 01:57 AM
Hey,

So I bought the SD2SNES Pro about a month ago directly from Stone Age Gamers and I am having a lot of video issues.

Normal SNES games work fine and are perfectly clear but when I load them up on the SD2SNES I get flickering or a few flashing lines.

Now I figured it maybe was a power issue so I went ahead and opened the system to test all the caps, only one was a little weak so I replaced it with the same challenge.

I'm using an original power cable and its my original SNES from 1991.

Any ideas?

I am having a somewhat similar issue except it’s less pronounced and only happens during the Iggy and Larry battles in Super Mario World.  I also noticed the odd flicker in SM RPG but no other games to date.

I’ll test Zelda tonight and see if it does this.  Any other games you experience this with??

I pretty much have bad video quality on every game. And generally just weird graphics artifacts on the top area of a game I can try others but even the main menu doesn't look great.

Ok that’s not good then. Do you have access to another SNES to rule it out?

Just tested Zelda and the intro scene was fine for me.

I saw this exact issue someone else had on a facebook group a while ago. I believe they were using a faulty power supply, so grab yourself another to rule that out.

Did you check inside the SNES to see if the capacitors are OK?

Ok I ran out to a local store here called Fallout Games (Local Plug :D) and picked up an OEM and a 3rd party power supply.

Both have the exact same issue and the 3rd party PSU is junk (adds a lot more noise to the video)

Yes I actually have the whole unit apart right now and tested all the CAPs only one was about 25% weaker (C64) I went ahead and replaced it but still same issue.

Any other ideas?

I would like to test another SNES but I don't have an extra one... 20/20 I should have taken the cart with me to Fallout to test...

Well some good news... its not the cart!

I was able to pull out my Super Famicom to test and it works fine... So the question is what is causing the issue on my NA SNES.

I tested all the capacitance of every cap and they are all fine. I can replace them all but I would rather not since I don't have SMD style Caps on hand for this if its a one off I don't mind redoing it.

Does anyone know what Cap maybe causing the issue? It appears to only happen on some types of graphics so I would assume its power not reaching the SD2SNES for one of its chips to display things correctly.

ideas?

Hi, have you already tried the “SD2SNES diagnostic firmware” or the “SNES Burn In / Test Rev.D Rom”?

Edit: On an NTSC SNES, you should always run NTSC Roms! PAL Roms can course such problems. If your SNES is modded, it should run all regions games without problems.

I'm aware of the NTSC/PAL rom difference, it has nothing to do with that.

I have not tried the diagnostic firmware or the snes burn in rom.

Any links to make sure I grab the correct things?

Thanks again for the help!

For an SD2SNES Pro make sure you use this diagnostic firmware, as Ikari's download webpage doesn't have the right one listed yet for the Pro series:
https://sd2snes.de/files/sd3snes_diagnostic_firmware.zip

For the burn-in cart, I am not 100% on the rules of linking to that since it's technically a ROM.  Just do a google search for SNES Burn In Cart Rev D and you should find the right one with ease  :)

What's the burn in cart again?

I am having the EXACT same issue. I sent my cart back to krikzz 2 months ago and just got it back. Same issue. I have an original SNES with the original power supply. Really frustrated.

Test results on the SD2SNES are all good.  Have you run the burn in cart ROM yet?

Would you check if turning on the setting "Reset patch for clock phase" in the In-game settings helps?

I would try upgrading the voltage regulator to a 78S05, as it supports up to 2A output current, unlike the standard 7805, which only goes up to 1A.

I have resolved the challenge (sort of) sorry for taking so long to get back.

I bought a beat up SNES from an Auction in town and removed the main board from the broken chassis and replaced mine. It works fine in the new board so it has to be a cap issues but I'm to lazy right now to resolve it.

One day I'll recap the whole board and retest.

I'm also having graphical glitches.  I was playing the translation of Dual Orb 2 and after about 20 - 30 minutes graphics start glitching during battles.  Also, can anyone else check out Human Grand Prix II?  That game glitches like crazy for me with the SD2SNES pro, but runs perfectly with the super powerpak.  It's the Japanese version of F1 Pole Position 2 (goodsnes 3.32).  F1 Pole Position 2 is the European version so if you have an NTSC console you might want to try the other one.

And for what it's worth my SNES is a North American SNS-001 model with a separate sound board.  It's been recapped, has a 2A voltage regulator, and  and has a 470uf cap added across the voltage regulator.  It handles every other piece of hardware I use on it perfectly, even the power hungry SNES Powerpak.

I seen problems like that  with original sd2snes  + pal snes which were used with famicom PSU (their PSU is compatible, bye the way).  At same time regular games worked fine. Not sure if this story also about problems with power supply, but at least it looks like that.

My original SNES (1991) always had problems with SD2SNES, so I got one from 1993-94 era, and it ran much better.

to me it was the complete opposite. The translated version of tactics ogre kept giving me problems on my sned mini, so I sold it and now use the sd2snes on a shvc model, 0 issues.
