Your out of your mind my opinion and I'm certified in soldiering he does a perfect Job don't worry about the haters they just wish they had your SNES skills

@@PunkNDisorderlyGamer Yeah, I Was Going To Say That My Comment Was A Joke, But Keep Up The Great Work With Those Super Nintendo Boards! I Know You Can Do It!

[@PunkNDisorderlyGamer]

@@delindarivera1671 I pinned it lol.

[@phantomexe9640]

Picked up a game gear for cheap. Figured I'd try recapping it. Love the videos. Keep them coming

[@PunkNDisorderlyGamer]

@@phantomexe9640 I’ve always had bad experiences with game gears. I hate working on handhelds. Good luck I hope it turns out well. 👍

[@mrweatherby]

Same, though I wish there was just someplace I could reliably ship my old consoles off to in order to have them recapped, just pay someone who knows what they're doing more than me lol.

[@DoomKid]

Love watching these repair videos man. Keep it up

[@joesaiditstrue]

4:00 that looks like a bad solder connection, have you tried putting pressure on the cpu and/or ppus then turning the console on?

[@PunkNDisorderlyGamer]

I try it sometimes but I never have any success.

[@BoomerElectronics]

Seems like questionable engineering if your electrolytic capacitors are outlasting your ICs in many cases 😵. I'll definitely give a point to Sega over Nintendo in that regard.

[@lincruste]

​@@PunkNDisorderlyGamer I'm definitly Nintendo's bitch and I love my SNESs, but Game Gear ICs do NOT die before their electrolytic caps. Anyway, SNES or GG, none of those machines were supposed to work 35 years after their release.

[@PunkNDisorderlyGamer]

@@lincruste yeah I definitely misread that comment. You’re right.

[@leex187]

I’m glad you tried to save the cpu from the coke bored it’s a shame it didn’t work but you had to try right to be sure

[@briansellers7673]

Great videos. I have three SNES`s that have faults and I'm building up the courage to try and repair them. I'm hoping to get one of the three working. I already have the diagnostic cart and a hot air station. I am hoping my soldering will be good enough because I've struggled with surface mount soldering before.

[@PunkNDisorderlyGamer]

300 soldering iron and 350 for hot air. But I may increase hot air to 400.

[@briansellers7673]

​@@PunkNDisorderlyGamerThanks for your response. I should have watched the whole video before I asked the question because you answered it in the video.

[@njones621]

What are the chances of figuring out the issue without the burn in cartridge? Those things are crazy expensive. Is your best bet to just start swapping chips? Really enjoy your videos!

[@PunkNDisorderlyGamer]

@@njones621 it’s possible

[@MizuhoChan]

You could just make one with a cheap game and an eprom. 27C801 I think it is?

[@TodoSobresaliente_oficial]

You can use a everdrive clone and load the rom from a SD. It is around 30$

[@MizuhoChan]

@@TodoSobresaliente_oficial Not much help if it won't boot that before the burn in tests though.

[@jeffcasper5844]

Mario Kart starts from its last save. If you last tested a board in 2P mode and picked koopa, it will default to that option. That's why it's starting like that. To "reset" it, beat the track with 1P as Mario. It's gotta have a time to record to save. Disclaimer, I'm not certain this always works or how its supposed to, but I know it always works for me.

[@PunkNDisorderlyGamer]

You may be right, others have said something similar.

[@DoomKid]

20:48 LMAO

[@Tele3C]

fantastic video 🖖🔝

[@mint_kyuu99]

iirc Super Mario Kart remembers your last menu option even after you turn off the game. And starting at 2P mode after playing 1P mode seems to be normal to my knowledge, since it also happened to me even on emulators

[@PunkNDisorderlyGamer]

Cool, it was always strange to me. Thanks.

[@rubenmejia4881]

Also in mario kart to cancel a selection you press the X button to go back a menu. It could be different since I got a japanese cart but give that a try to see if it works on the american version as well

[@thecoldbootchannel]

Where can you get that burn in test cartridge thing? I’m having issues with mine, not sure if it’s cpu/ppu. Did a recap but that wasn’t the problem. (I posted my problem on my channel)

[@PunkNDisorderlyGamer]

@@thecoldbootchannel I got mine on Etsy years ago, but there are cheap ones on aliexpress.

[@OmgItsSpruce]

I had one where in SMW, DKC, and Super Metroid I would get like black bars above pipes and some glitches here and there etc. Samus would disappear and reappear, almost like pulsing and stuff. Any idea what chip it was? I was thinking PPU but I have no way of repairing it so I just sold it on.

[@PunkNDisorderlyGamer]

@@OmgItsSpruce probably a ppu, not 100% sure though.

[@OmgItsSpruce]

@@PunkNDisorderlyGamer I don't remember what equipment you use. Is it an FX-951 and FR-301? What hot air station? I use an 888D but it's time to get the other pieces so I can do more involved repairs like this.

[@JDPeters538]

Where does the owner get all of these? That's a ton of boards!

[@PunkNDisorderlyGamer]

@@JDPeters538 it’s a game store, when someone comes in with a broken SNES, he offers a quick board replacement as a service. People usually accept it because it’s done the same day, and they leave with a working snes. It comes out much cheaper than buying a new snes, and as a bonus the owner gets a part board that might be repairable.

[@rossgirdeen3247]

My controller stops responding in the middle of game play its not the controller or the controller board they have been replaced i was told it could be the cou?

[@PunkNDisorderlyGamer]

@@rossgirdeen3247 yes the CPU can cause the controller to stop responding. Just curious what game were you playing? Is your console corrosion free on the inside?

[@rossgirdeen3247]

@@PunkNDisorderlyGamer the console is pretty clean. I've went through and cleaned it as much as possible. Some games run pretty smooth such as donkey Kong country. It does have a small glitch. Really start to notice it on mortal Kombat 2 during this game both controls held down on the same button have the same issue.

[@rossgirdeen3247]

1 and 2 player controls glitch out the same

[@PunkNDisorderlyGamer]

@@rossgirdeen3247 that’s bizarre, it’s probably a faulty chip then.

[@74bobby]

Thats alot of CPUs, it would be cool if someone sold aftermarket cpus to replace Bad ones...

[@PunkNDisorderlyGamer]

@@74bobby one day they’re gonna have to

[@markianclark9645]

​​@@PunkNDisorderlyGamer...ok...then an FPGA in the same package will have to be created...the community haven't put any effort in so far...makes me think it's too much challenge... especially when you have boards like Super Players and it's clones..that does exactly the same job for 50 dollars..if those Chinese consoles all disappear from AliExpress then maybe just maybe the community might see a demand...meanwhile I have an original SFC (which surprisingly still works) and a Super Players clone..subnote...the latest clones have a wireless connectivity too..of no interest to me..I prefer wired

[@jimdavis6833]

Are you using a magnifying glass or a microscope?

[@PunkNDisorderlyGamer]

@@jimdavis6833 a camcorder zoomed in and naked eye. I do have a microscope I use to check coins, but I don’t like it too much for board repair.

[@tcscomment]

IMO if the graphics are corrupted it's a PPU issue and if there are no graphics it's a CPU issue

[@tcscomment]

also, for future you: PPU1 renders graphics (background layers, sprites) and applies transformations (scaling, rotation, etc) while PPU2 applies effects (such as window, mosaic, etc) on top of the graphics rendered by PPU1

[@tcscomment]

so for example if Mode 7 games don't work properly, it's very likely a PPU1 issue

[@SamuelClanton-j8x]

I tried putting in new cap kit and reflowed all the chips I'm still getting a DMA fail on the burn in test Donkey Kong plays none of my Zelda's play Bro could you please help me out Bro I have a 93 board it has a PPU 1 and PPU 2 chip hit me I would really appreciate it I need a part's board

[@PunkNDisorderlyGamer]

@@SamuelClanton-j8x for parts boards try your local game shop or ebay. Keep in mind Super Famicom chips are compatible, super famicoms are also much cheaper. I wish I could give you a chip but these aren’t mine. Sorry

[@SamuelClanton-j8x]

@@PunkNDisorderlyGamer that's cool thanks for the ideas I tried eBay and the town I live in nobody repairs electronic my uncle use to when there was a Radio Shack Fam Com and SNES are for sale around $150 around here not working 😕 Thank you for everything

[@Mo7-7]

sell me a APU chip brotha! you are snes rich! lol

[@PunkNDisorderlyGamer]

Believe it or not, out of all these parts boards not one of them have an APU chip. Plus these aren’t mine, this whole lot was from a local game store I gotta return it to him. APU chips are harder to come by.

[@Mo7-7]

@@PunkNDisorderlyGamer I believe it man. That's pretty awesome working with a local game store. I see it keeps you busy. Keep the video content coming bro. It's very educational.

@@Mo7-7I’m gonna ask for more work. Either Monday or Friday I’m going down to the shop to return these boards and see what else he has.
