Im the guy who recommended for you to check the brazillian service manual, good to see that it will result in a translated manual for everyone fixing snes's. That priority table is a must have in conjunction of the burn-in cart. In my experience fixing snes's, Mario Kart, Super Mario World and Donkey Kong Country are the ones that most easily show you faults related to PPU/CPU and VRAM (even the misterious ones the burn-in test doesn't catch) , so always have them nearby.
Yes you were, and thank you! It's certainly a handy resource. I did translate the burn in priority table when you pointed towards it last year, but I was curious to know what else was in there, so it needed to be done
I’ve never seen bouncy mode 7, or erratic controller inputs like that. I’ve had bad mode 7 in various other ways, and I’ve had CPU fails with controller inputs, but never with the controller idle. Very good to know. Good job 👍
@@senilyDeluxe damn you just gave me an idea, I feel like socketing a snes board and saving my dying chips and try and see how far in SMW I can get with failing chips. 🤣 if the QFP sockets weren’t so expensive I would totally do it.
@@PunkNDisorderlyGamer yeah the only sockets I found are like 100 bucks each. Do you still have all your bad chips or did you document which ones were bad? I'm curious to know what your stats are
@@TheRetroChannel I had a bunch of CPUs and PPU1s and very little PPU2s. Sadly, I tossed all my faulty chips away. I want to say it’s was 40% CPUs, 40% PPU1, and 20% PPU2. I’ve never had a bad CPU-B or WRAM chip, unless it was physically damaged. Bad audio chips are rare as well, I usually don’t replace those, I use those boards for donors. In my experience the only audio chip I remove is the rarer APU chip to save 1-chip consoles, and when I remove it I use chip quik low melt solder, for some reason heat destroyed 2 APU chips on me. As for sockets, I’ve seen $70 plus for one socket. That’s crazy especially since I would need 3.
@TheRetroChannel Concerning MicroSD card formatting, don't use Windows. Use at third party partitioning utility such as AOMEI or EaseUS. They will format anything to any format as they actually follow the specifications rather than doing whatever they want like Microsoft does.
I find the liquid does a better job with fine pitch stuff, even though it doesn't last long. But I have a litre of it so not going to run out anytime soon
@@vhfgamer It's very easy if you know how to use it correctly. I've been using gel flux for ~20 years and never had any issues and I'm doing a lot of SMD work including replacing very large QFP chips with up to 304 pins with 0.5mm pin spacing. It's all about skill and technique....
I think maybe you should try resoldering the chips before they are condemned. Might be throwing out some good chips unless you are doing it later. In vehicle diagnostics if there are multible indiscript errors there is often a power supply problem, I dont know if that applied here.
@@vhfgamer Yeah that's possible but from the evidence at least half of that hypothesis is bunk. It's also very easy to jump steps or have thought errors. I had one just the other week while diagnosing a car where I was measuring some pins on the wrong side of the circuit. The diagnosis turned out right anyway though. Power problems can be very elusive since you usually only measure votage and not current.
even though the manual says to change ppu-1 on that high ram failed board i think you should try changing the sram first if only because it seems like it's something you have more of
The service manual says work ram fail... fix is change CPU. That's a new one lol. I would change the ram first. Having fixed several thousand arcade boards I know for a fact RAM is the most failed chip on any board.
FAIL on only ONE of two RAM chips more likely points to that particular chip. A failure somewhere outside the RAM chip (on the data bus) will influence BOTH RAM chips.
If one board's chips can fix two other boards that's a net gain. He's also properly doing these chip swaps so the donor boards can be repopulated later if more chips are found
@bobrocks95 yeah... but if he can fix 2 other boards using the chips from that 1st one, it means that the other 2 boards together also have a full set of chips. At the end it is probably the same, but I would think that if one board works it would be better to keep it and work on the others, it would mean fewer desoldering/resoldering operations, which take time and also are kinda of traumatic for the chips I guess (admittedly I have never tried any SMD, perhaps for a skilled and experienced technician it much less of a risk than I imagine 🤔)
@@enjibkk6850 It's not great, but mostly from the risk of damage rather than the inherent act afaik pin-wise.

28:26 Not exactly another program to format SD card over 32GB. GUI doesn't let you but from a command line you can format larger drives / SD cards as FAT32
Believe it or not I did try this a few weeks ago when they announced windows 11 will finally receive an update to allow for it. From the command line it did appear to work with a 64gb SD card, but at the end of the format it errored out with "this volume is too big for fat32". Why it doesn't tell you that at the start I don't know
30:28 What flux are you using? That stuff looks like rubbish and you're getting solder bridges almost immediately. With the high quality proper smd flux i'm using I don't get solder bridges for several minutes until the flux burns off.

“A fully working parts board” 😂😂😂😂😂
It's always a pleasure to see SNES repairs, especially when they're successful. Really neat work. ✌
You've improved your soldering skills over the years. Good job! That surface mount work was darned clean looking.
Your voice brings me down in every video. Something to learn and something to enjoy, especially in a calm environment. Thanks man!

Maybe it's worth checking the chip legs and reflow them before replacing them.
On the way to 100K. Quality work.

Wonder if those bad chips can be recreated in a feasible way
Love the use of fume extractor!
PPU failures on the older 2-chip revision is quite common
Have you tried using the more paste-like/gel flux? That liquid flux seems to be spent very quickly.
I find the liquid does a better job with fine pitch stuff, even though it doesn't last long. But I have a litre of it so not going to run out anytime soon
Paste makes it hard to line up the pins. The chip gets sticky and resists movement. You end up having to put way too much force into it.

I think he eliminates power problems by mass replacing the 7805 voltage regulators and by using a decent bench power supply.

Haha, yeah it sounds strange but with the SNES the CPU is the most likely thing to die
very good
You should be able to fat32 from the disk management console (right click start)
Last time I checked it was still limited to 32gb, but I know windows 11 is finally receiving an update to allow larger than 32.
That limitation of formatting FAT32 is removed in Windows 11 and you can now format up to 2TB.
But who cares when you can use Rufus ...
I heard there was an update coming to allow for it, but at least on my system it was still limited to 32
i wonder if the cpu was bad or if the issue was the cart port
Definitely the CPU
FAIL on only ONE of two RAM chips more likely points to that particular chip. A failure somewhere outside the RAM chip (on the data bus) will influence BOTH RAM chips.
😢I was across getting some pizza so instead of your cookie you may have 🍕
Thanks, I just had some 🍕
Looka like if you where using originally cart's you wouldn't see most of these faults only with a everdrive
Buuuuut WHY sacrifice that snes that is now functionning ?????
