That's electrolytic corrosion - basically electroplating in reverse. Instead of adding metal, it carries it away. That's also why it's only affected pin 8 on the SRAM supervisor chip, since that has battery power at all times.
These games were caught in a house flood when a barge broke loose and ran into a dam, I bought them as a massive lot. Post forgot to bring news paper to pack with...Thats why it was not packet well....
All of my N64 games stopped working, and I thought at first it was a problem with the game console itself, so I replaced it and no luck. Then I rubbed down the contacts on the cartridges with isopropyl alcohol on a Q-Tip and immediately every single game started working again.
That chip is the voltage controller for the sram. It switches between battery power and main power. That pin that was broken off was either ground or Vcc. So a very important pin
Looks like you put the chip on backwards. Just a heads up. Could be wrong it’s hard to see on my phone but the dot for pin one looks opposite the board marking.
No he didn't. Whoever botched the initial repair did. If you look at the donor card, the chip is in the correct position. This is probably why the chip suffered btw and burnt the pin and the trace, it was put upside down.
@@insanedruid3143 I disagree. The silkscreen looks to be wrong on the first PCB BUT the resistance SMD is positioned on the exact same pin. Wrong silkscreens on commercial pcbs is nothing new. This probably led to the wrong repair in the first place. Obviously the cart wouldn'T work before and is working now. The Amiga CD32 and the Amiga 4000 have wrongly polarizzed silkscreen for two capacitors for example yet were properly installed at the factory level.
The dude shipped those cartridges with no packing at all. Couldn't be bothered to throw in even a couple piece of free newspaper to keep stuff from banging around.
doesn't it look like the IC failing is the reason why the pin was completely vaporized to the point where it burned the trace right off? or it could have been stuck in a broken snes that burned out the IC...
Something tells me the pin was eaten away by something because whatever ate the pin also got in the trade and ate that too. I could be wrong though. In any case, it's working which is epic! Nice work!
I recently bought this game and I had to do some cleaning and everything seemed to be in place no damages that were shown in this video but it still goes to black screen and other games do work on the system
Happy New Year, sir. Interesting enough I just purchased Megaman 2 nes cartridge that had issues so I took it apart cleaned it with IPA & used a soft eraser on the contact pads, once finished the game worked flawlessly.
I know it's a stupid comment but it's as if it was not as much fun to watch now that you are fully equipped haha. Just kidding, I still love this no bs editing, great repair video. Happy new year man.
@@FamousMovieScenes09 A lot. Surface mount components could have been ripped off the board. The carts should have been reassembled and packaged properly. If I had bought this off a site like eBay, this seller would be getting an immediate 1 star rating for this bullshit. Completely unacceptable.
Looks like the IC was orientated opposite on the donor PCB, and you forgot to flip it over during the transplant? And I'm curious what the Yoshi's Island does with a bad FX chip. Just messed up graphics?
Someone's tried to remove U4 before and on pin 4 the solder hasn't melted properly (no rhyme intended). They've pulled on the IC lifting the pad, and then instead of stopping they've carried on and then snapped the leg off. They then left a road crash of solder on pins 1,2 and 3. EDIT: On second thoughts they could have just burnt that pad away.
As a job I don't know if I would enjoy this work. I'm not even sure I'm subscribed but I love watching this so much TH-cam always suggests new content. I'll sub now I guess lol.
That missing pin wouldn't happen to be the positive would it? Because I've seen the same damage from the time my dog pissed on a USB hub I was using to run a cross the living room floor. The first hub chip was toast in the same fashion. The second I salvaged to replace one that caught fire in my keyboard. A month later it also caught fire. Thanks Daskeyboard!
This may be a dumb question, but can I ask why you didn't take that crusty old battery out throughout this whole process? Trying to preserve the saves? I just figured you'd have taken it out before the initial board cleaning...
The chip in question looks to be this: snescentral.com/chips.php?chiptype=MM1026AF Its purpose is to prevent power spikes to SRAM when the console is powered on and off, and looking at the fried pin, likely got a bit too much of a power spike from the looks of it.
Happy New Year 2020 Adam ! I cant believe its almost 2 years now since I became a regular watcher. Congrats on making that Mario RPG working again. Have you ever considered buying the knockoff carts for parts, or are they using different architecture ?
When you are going to post the Ocarina of Time Repair?, i really appreciate N64 repair videos, i looking forward to see if it's possible to save that board.
I think there's a pull tab along the edge of those USPS boxes... you just pull the little ripcord and it opens like it was sealed. Not that watching you jab your thumbs in wasn't fun lol.
ill like to see you bring back that zelda game 😁 you would be Dr Frankenstein if you did cause it looked awful. good job on mario rpg. brings back memories.
I bought a unit that plays both 64 and regular super NES the small cartridge just like it working on there it quit where the front one quit working on me I was just wondering if you might want the unit to have something to work on to show your friends that you can get it going again it quit working with me it's a hyperkin unit I just didn't know what to do with it I got it in my room stuck in its box but I was just wondering if you might want to take the unit and try to get it working again for somebody else later have a beautiful day
How much would a refurbished cartridge sell for? And how much does a non-refurbished but good condition cartridge sell for? How much value does a cartridge gain if it is well kept rather than refurbished?
That entirely varies. A working super mario rpg cart in similar condition is probably worth about $50-60. Refurbished isn't always a bad thing, in these cases, having replaced the save battery can maintain or even improve value. If it were a replacement shell or label, then it wouldn't even be worth $25.
@@RetroRepairs oh ok! i figured it was along those lines but figured I'd ask, thanks a ton man! trying to get more into repairs and such as a hobby. Thanks again!
You're talking about that 3v battery? Not really, no. 99% isopropyl alcohol is barely conductive at all. Water would possibly be a different story, but even still at such a small amount, the resistance of the water itself is likely too great to transmit current where it shouldn't be.
Why not just use a wire and make a bridge? Soldering one side of the wire directly on the chip (instead of the broken solder pad) and the other side directly to the capacitor. It's a commonly used method for this kind of problem. But well, as long as it's working anyway ;-)
@@RetroRepairs Yeah but I mean, you didn't really had to expose the green thing? Wouldn't just a wire directly soldered to the pin then soldered directly to the capacitor would not be enough ?
It's one of the ones that has both. A ring of harder ones and some softer ones around it. It doesn't really matter too much, hard bristles wouldnt damage the board
Hey i recently fixed my full of rust controller's battery pack by bathing them in vinegar and cleaning with a toothbrush. Can you just drop the cartridges board the same in vinegar. Will it damage it?
It depends on the game. Some of the Conkers carts I bought for $30. Something like this super mario RPG would probably sell for 15-20. Cheap ones, 10 or less
Bad current going through it? Who knows. Snes has notoriously bad caps, so entirely possible an incorrect current ran through a chip and killed it. Happens all the time to the cpu. That's my suspicion anyway, but i haven't swapped it yet to truly verify.

When it comes to broken pins from the IC package, some people carve the IC to expose more of the pin and stick a bodge wire on it.
Yeah, i might go that route to put it on the donor cart for a future repair

They use a completely different architecture, so it's very unlikely repros would be useful.

It's definitely fixable, but i haven't started. I need to get some parts
I have this same cart. I need to pinpoint the reason why it won't save despite me buying and installing a new battery for it.
SRAM failed.

As long as it stays in place, yeah it probably would. Id question whether the adhesive would hold up to soldering or not
Yoshi Island has a bad FX chip? Do you still want it?
Yes, ive got 3 that don't work so i want to find the fault and make 2 of them work
