Super Famicom, Bad PPU or Bad Game cart?
Posted: Sun Jun 26, 2016 1:49 am
So I recently pickup up a super famicom from ebay, a long with some games (separate seller)
Of the three games I bought two had issues.
super mario world played fine,
But the main title screen, and anything using special overlays, such as text box popups (in game notices) it would have weird glitching, but it would all be limited to that frame.

But just normal level play was fine.
The other game that had some slight issues was street fighter II turbo:
more:
Again, most of the layers seemed fine, but a few sprites were messed up. (as shown)
But the characters look fine.
The Third game was super bomberman, that plays 100% fine with no issues, and I later picked up 'starfox' and that plays fine with no issues.
I've cleaned the games (properly), as well as completely Cleaned the console inside and out.
And I still have the same issue.
I opened up the SMW cart (https://imgur.com/a/8lzbm) , and the contacts looked pretty corroded, is that a likely cause?
Because Sf2 turbo's look much cleaner, but it still has issues.
I also recently had a hard crash in SMW while just collecting coins, and it reset my save file.
---
So long story short, I already have a return in progress for SMW, but I'm wondering if it could have been more of a PPU issue, Both the SFC and game seller say they test everything before it's sent out, so I don't really know who to believe.
I've already spend $16 on a whole new power supply (as suggested by a guy on /r/snes)
and now I'm at the end of my rope, I can't find any similar issues on the internet.
The guys with bad ppu's tend to have much more glitches. (whole sprites messed up, multiple layeys corruptted.)
And the guys with game cart issues tend to have issues with standard game play, not just menu's. (eg, games not starting up, constant freezing)
Any ideas on how to tell what's causing the issue?
