You got the creepypasta cart.

Run.

SHVC failure

Thats fucking awesome. Post more pics!!

>>6082261
>SHVC
You had me going here, but SHVC is just the product code for the Sufami itself.

>>6082258
Did you receive the console this way, or did it just suddenly happen despite having worked fine previously? Did some incident precede the picture turning into this?

>>6082327
And the first run European SNES prone to VDP failure

You can SEE the ghosting, fucking gross

>>6082523

Are you saying the koopas are walking backward, and thus leaving faint "shadows" of themselves ahead of their front sides? Do koopas walk backward in this game?

>>6082327

Are you saying that a troll's post is worth reading and responding to?

>>6082258
Your snes is haunted.

The camera's shutter speed was not identical to the refresh rate of the monitor, or was not synchronized to the refreshes of the monitor. The image we see in the OP is thus a double exposure of two frames, with mostly the first frame (where the dark figures are well defined) having been exposed to the camera, and a shorter fraction of the exposure seeing the second frame (where the koopas have moved a little bit to the left).

Some part of the gpu has failed. There isn’t anything you can do to fix it aside from soldering on new chips. Which you’d have to butcher from a working snes to do so. Just buy a new one. Preferably a 1chip or a snes junior.

You have to beat the game that way now OP

>>6082258
open the SNES and take pics of the board.
It could be PPU failure, but it could also be something easily fixed like a dead insect bridging the pins, or something less simple, but still fixable like corrosion on the chip or a damaged trace.

>>6082623
>>6082583
Probably not. OP just needs to clean his cart and slot with contact cleaner. His snes is likely fine. Toothbrush and WD40 contact cleaner should do the trick

>>6082725
literally retarded

>>6082824
I’ve literally seen this happen. Usually “broken gfx chips” are just really really dirty or worn contacts. Do you know how rare it is for those to actually break?

>>6083491
Yes

But OP doesn't have to take any body's word for it, he can just open up his console and gently tap on chips until he sees an alteration in the glitch.

>>6083497
>gently tap
If he uses a hammer then he'll be sure to identify a broken chip.

>>6082258
16:9 for starters

>>6083491
>I’ve literally seen this happen
No you haven't. You may think you have but that just shows how ignorant you are.
>“broken gfx chips”
Also shows how ignorant you are.
>Do you know how rare it is for those to actually break?
Just because something is "rare" doesn't make a fool right

>>6082258
Broken DSP, might as well throw that SNES in the trash

>>6084787
He could still put a raspberry pi in the case

>>6082258
damn, try opening up the cart and checking the PCB. its possible the wattage is outright shorted, and needs to "resurrected" in a sense. in order to do this safely you need a pair of electric deterrent gloves (very important) and a non-stick polymer multi-base adherent that can be aerated in a natural open space so as to not upset the OC3 optical line. Once you've applied the right amount of paste (no thicker then .2 centimeter on the RF board connected to the GSM chip) then you can leave it out to dry. After its dried for about 8-12 hours you then want to put it in the freezer. after about 20 minutes in cold enclosures the melding paste will now be able to resuscitate the "BV-XGP" processor, this is done now further by checking the voltage and continuity present in your cart. Make sure you use a high rated voltage meter that can go to at least 120/240 or your fucked man.

>>6084924
DO NOT DO THIS! It creates islamists.

>>6084936
well, on the contrary; the original PCB has a base plate of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two main spurving bearings were in a direct line with the panametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-deltoid type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible tremmie pipe to the differential girdlespring on the "up" end of the grammeters.

But I understand.

>>6082258
Enjoy your cursed SMW

American SNESes used it too, but all american/japanese SNES systems had SHVC printed somewhere or another on the PCB as an actual relief in the ground plane. Silkscreen printing did differ though.
>>6083491
I've repaired a lot of consoles in my time, but those early SNES/SFC units are pretty weird. I think i've had a couple where they just had bad RAM, but more often than not a PPU was bad.
>>6083497
A lot of those chips are CPU's. I've rarely seen CPU failures in SFC's/SNESes. PPU's, though, yeah.
I'm partial to the 1chip units, but I have a non-launch 'two-ppu' snes as well.
And an SPC module from a launch unit I hope to turn into a midi synth some day (using system exclusive messages for programming, sort of like an MT-32 but with a slightly more modern wavetable design).
>>6084838
If it weren't an early unit that yellowed like hell and was so brittle it was impossible to screw back together, sure.
(at least, that's true of american launch units)

I almost chuckled.

>>6083497
In 30 years of fucking with various electronics I've personally never had a GPU fail.

>>6085041
I’ve repaired a lot of these broken snes and either reflowing the PPU and RAM fixed it or more commonly just cleaning the contacts.
>>6084651
I put it in quotes because I was being facetious.

>>6088281
>I've LARPed a lot
indeed

>>6082258
This is probably a bad CPU. S-CPU and CPU-A commonly fail. S-CPU is found in SHVC consoles while CPU-A is found on SHVC, GPM-01, and some of the earlier GPM-02 boards.

PPU failures are also common. However, if one of the PPUs is bad the game will still usually at least run. Normal gameplay is usually still possible, though you may only be able to tell from the sound. PPU failures usually only cause distorted graphics, but won't usually cause games to fail to load, crash, or glitch.

Take a game you know well and try playing it. Even if the graphics are distorted, try to determine if it's running normally by the sound alone. If it fails to load, crashes, or if there are any abnormalities besides the distorted graphics, then it's almost certainly a bad CPU. If the controls don't work that's also a dead giveaway that the CPU is bad (assuming the controller, controller port assembly, and the flex cable connecting it to the motherboard are all good).

I've never personally seen a VRAM failure on an SNES, nor have I ever seen the S-WRAM fail, so I wouldn't worry about those unless you can first rule out the usual three suspects.

If all games seem to play normally other than the distorted graphics, then you'll need to do some further troubleshooting to determine if it's a bad CPU or if it's one of the PPUs. I can't really help there, but if you have a flash cart you can try running the burn-in test rom. Sometimes it can help give a clue, other times the console will pass all tests and you have to just keep trying various games until you can figure it out on your own. One of my test games, for example, is Yoshi's Island, since vertical lines on the file select screen usually means PPU1 is bad. You can also check DogP's logs to see if you can match your problem to any that he already fixed:
