Unmodded SNES: graphical issues on shadow tile or vector

[2bitgamer]

Hey guys,

I want to ask if anyone has seen a graphical glitch like this on their Super NES before? I will just mirror what I wrote on the youtube descrip:

My sweet, cheaply acquired SNS-101. The heavy one. And, baby, I can use an S-Video connection on this one. Man it looks so good. However, there's a problem. Games that play fine on other SNESs (Model 1 or 2), exhibited issues exclusive to this one.

You may immediately notice that Super Mario World has something wrong with the shadow underneath the grass. Instead of a black or dark brown, it is turquoise or light teal. This also occurs with Super Mario Kart. You will notice shortly into that segment that the question blocks are not outlined with black, but also in teal/turquoise.

Seeing that this anomaly occurs in both a tile based-game, as well as a Mode-7 game, I am *guessing* that it could be a vector/draw problem?

This leads me to ask: Is this issue with merely loose contacts or is it a graphics chip issue?

Sorry for sound being out of sync. Will use Linear PCM next time. Also, I will try to find other games that may expose this problem in a more visible manner. Thank you in advance for your input.

SNS-101 with color issues(or is it SNS-001, since you mention "the heavy one")? If you got an SNS-101 system and have color issues, odds are your system is a fake from China. If not, it could be a PPU issue. If you've got an SNS-101 system, take pictures of the system from all angles and the motherboard if possible.

Before I take pictures of my system, I am 95% sure it is a real SNS-001, Model I NTSC Super NES, Made in Japan. My lack of posts and history on *this* board may suggest my experience as lacking. I assure you I can smell a fake from a mile away, even in many things unrelated to video games.

I've seen comparisons of the fake SNS-002. Here's why I think this SNS-001 is real:
-Typical, non-uniform ABS plastic yellowing with age on top section
-Embossed Nintendo logo is correct font, with sharp defined corners
-Texturing on plastic is present everywhere, cart slot lid, buttons, eject, body, even under unused extension slot
-Metallic stickers use the correct font, boldness, placement
-External linehead screws
-Correct weight, color (of non-yellowed area), and warranty sticker.

So let's just say it isn't fake. My only solution is to replace the PPU or motherboard? Any more ideas?

Okay, no, your system is guaranteed legit. There were never fakes of the original-model Super NES(SNS-001), only the Super NES Mini(SNS-101) had fakes produced.

You may want to first give the cartridge slot a good cleaning. To do this, wrap a little towel around an old credit card or another card about as thick as a credit card, spray some Windex on it and clean the slot. If that doesn't work, you might need to clean the slot on the INSIDE of the Super NES. Some original-model Super NESes, mainly those with the SPC700 sound processor on a separate daughterboard, have a 2-piece cartridge slot, so maybe there's some corrosion between the cartridge slot itself and the piece that it's plugged into(that piece is soldered to the motherboard). Try that first. If it doesn't work, you might need to reflow the solder on the two PPUs. If that fails too, you need a replacement PPU.

Just to be sure, this happens even with different copies of the same game?
