Pokemon Red Game DESTROYED by Liquid - Let's Try to Save It!

[@Tronicsfix]

PCB Design Attribution: PCB Design Attribution: github.com/HDR Above is where the PCB design came from for this new PCB. Also, I've been made aware by several commentors that the plating on this PCB is not ideal for this application. If you decide to have this PCB printed it's much better to have it gold plated so the contacts last much longer. Read the comments below to learn more from people who have a lot more experience with this than I do.

[@dav3yb]

The only thing I would change about the PCB, if you're going through the trouble, is changing up the battery area to allow a slide in battery holder, so you can avoid having to use and solder in tabbed batteries.

[@PiiAreSquare]

Great work as always. But I have to agree with many other member comments. As a PCB application engineer, I do not recommend HASL, Tin Lead, Immersion Tin, OSP, Immersion Silver, or even ENIG finishes on pads or copper features that are meant for multiple touches or insertion edge connectors. ENIG is a good source for solderability but not durable enough for edge connectors as wear and tear would still cause gold breakdown/flaking and exposing copper for corrosion. I recommend future designs to use a minimum of 30uin of Hard Gold with a rating of 99.9% knoop on top of 150-200uin of nickel plating. This application better suits edge connectors and touch pads (like the D-pad or buttons) due to the thickness of gold for durability reasons. This will cost more of course, but these boards are typically manufacturing in multiple images on an 18"x24" production panel or larger which brings cost down significantly. Individual piece orders will be the high cost driver.

[@RestoreTechnique]

@@PiiAreSquare oh man, that makes small batch PCB ordering so expensive. I wonder if these gameboy cart replacement pcbs can be purchased at a good quality, by someone who's made them with the hard gold connectors 🤔

[@AkiraPoland]

I was thinking. Maybe try fix: guitar from Guitar Hero series on PS3 and Xbox 360. They are rare to find in Good condition for small price, only broken are cheap. Also problem is that last game was sold few years ago And is not continued. So they only get more and more expensive.

[@rfmerrill]

It's generally agreed that the best finish to use is hard gold, but it's not as much agreed upon what the second-best is. IMO the more important thing is the edge beveling. I haven't finished the video yet, but for any game cartridge PCB you want to make sure the connector edge has a bevel or chamfer on it so that it spreads the contact fingers of the slot more gently. You don't see this on edge connectors for other applications typically because they're not intended for many insertions--e.g. how many times do you remove and insert things to a PCIe slot, maybe a dozen or two?

[@jylam_]

As I designed GameBoy cartridges myself, I can point out you made a small but important mistake while ordering the PCB. It seems you chose the cheap HASL finish, you definitely should have chosen the ENIG finish (Electroless Nickel Immersion Gold). With HASL, after some dozen insertions into the connector of the GB, the plating will wear out and you'll be back to square one with a non-functional cartridge. ENIG is quite more expensive though, but mandatory for GB cartridges.

[@ramcade31]

Agreed… I have had issues similar to this with fake gameboy games

[@jamesdavies686]

Yep, he screwed up by cheaping out on HASL instead of getting ENIG. Big no no and RIP the gameboy that see's that game.

[@jylam_]

@@jamesdavies686 Yes. To explain to the 2 persons reading this, the plating can just peel of the trace and short pins on the connector.

[@gedi223]

Funny, I just watched the video and was going to comment the same thing about the finish.

[@jimmysmantzas]

wow, this is why videos like this are so great, because the comments are an even greater source of information, thanks

I am only j-std certified in soldering but by watching your videos I have up my game at my work. I have acquired some of your technics. Thank you so much for showing us the repairs that you do. You are an awesome teacher. Thank you so much 🎉

[@techman2471]

New boards, old chips, great video to save another great electronics device out of landfill. BTW, the free red Game Boy... pls do a video on that.

[@NWquadriders]

Unfortunately, wrong plating on the gold fingers so cartridge will fail shortly and end up in a landfill unless swapped on to a new PCB

[@Chaft015]

@@NWquadriders could you elaborate a little please ? that seems interesting.

[@NWquadriders]

@@Chaft015 The contacts on the Gameboy connector and the card edge fingers on the cartridges are gold. By using a tin finish on the card edge fingers on that new PCB, this will cause galvanic corrosion. This is oxidizing of the surfaces resulting in unreliable contact and could cause damage to the connector over time. Never mix tin with gold contacts.

[@Chaft015]

@@NWquadriders Thank you for the details, I didn't know that, that could explain why gold plated connections are so sought after in electronics. Edit : I read that too fast sorry, I understand now, it's crazy how differents metals react to one another.

[@Tronicsfix]

Lol, I almost did that!

[@Max-uv3eg]

Really appreciate your in depth explanations of the smaller things recently, like why you're tinning the pads etc.

[@MarcelSchr]

I could also imagine the thick circuit board bending the gameboy's contacts. Good that you have a thinner one

We want to see a video on the gameboy pocket being fixed, Steve! Good idea for a video.

[@smedlap8789]

I am a nerd that enjoys fixing my own things so much that I enjoy watching you fix things. Good job! 🤓

[@duckm02]

Im about start 😔

[@Anonymous-fw7tt]

What surface finish have you chosen for the PCB? Looks very much like a simple HASL finish to me. That's very suboptimal for the edge connector. It'll degrade much faster and oxidizes rather quickly, making the game more unreliable. Oh, and the HASL finish is going to rub off onto the cartridge connector of the gameboy making the gameboy itself also more unreliable at reading cartridges. For such PCBs you should always use ENIG finish at minimum but optimally hard gold.

[@border056]

Unfortunately, this board swap is only still going to work temporarily. The board was ordered with a hasl finish, instead of enig or hard gold. The solder on the cart pins is going to oxidize quickly and become non conductive. The best repair would be rom swapping it to a cheap Japanese donor cartridge and then put the Japanese donor parts onto the replacement PCB with an enig finish.

[@XrackProject]

Hey, thanks for this usefull information! Could you maybe also tell us where to get good quality PCBs for gameboy games like this?

[@vinnycordeiro]

I noticed that as well, but the thing is that ENIG finish is expensive. Unfortunately it is a necessity on this case.

[@Tronicsfix]

Hey thanks for the comment. This is good to know as this is the first time I've ever had a PCB manufactured. Now I know what to look out for for next time!

[@ramonpagan695]

Can you fix my gameboy metroid card? Is not saving my file and I did replace the battery.

[@12345.......]

Holy tetris flashback! I miss Gameboy And of course we want to see a Gameboy fix

[@Tronicsfix]

That’s what I like to hear!

[@sininails]

Too bad the case isn't clear... That's a mighty fine looking board.

[@LogicException]

3:00 I don't know if it still comes in the video but here you can see in comparison that with the new board the inner pins are too long. Left is 5V and right is GND. This is necessary to not roast the chips when plugged in when powered on and to make a clean contact with GND first. Just a side note.

[@AJGotGames]

I would've never thought to get a new board made for an old game! Awesome creativity and entertaining video!

[@louroboros]

Oh hey, I did exactly the same thing to get my childhood copy of Red running again. I even fixed a typo (used to read “KDFN”) in HDR’s PCB design and got it merged in, which I can see you used in this video! Was a really fun project and my first time ordering PCBs. I was shocked it worked - thought for sure the ROM was corrupt.

[@bluedragon219123]

Seeing the hot air gun working so close to a battery SCARED me. Blessedly nothing happened. Great Job! :)

[@ferrarimintdaw5242]

[@hawkfeather6802]

[@mathiasschneider9113]

Excellent job. How did you procure the replacement board? Did you study the original's layout and apply it in the PCB software, or find it available somewhere?

[@alexeizavjalov8889]

The traces look different - I would guess he draw the schematics and used autorouting in "PCB Design Attribution" CAD software (see the first comment).

[@benroyz]

Lowkey, I'd watch an entire video of you just cleaning out the board, cases, and all sorts of that stuff. Great video, would love to see you repairing that red Gameboy.

[@goodi2k7]

As an electronics engineer there are some interesting differences between the old and new board which makes me wonder if the guy designing the new PCB didn't really understand what's going on. For example on the old board there are many many vias connecting copper areas on the top to the bottom layer. All of them are missing on the new board. Also, some of the pins of the ICs are connected to what I guess are big power/ground traces. On the new board the are connected to tiny traces. But if it works it works I guess... Also, is this a generic PCB or is it for this game only?

[@skynet0912]

Now i'm even more impressed that my Yellow version not only survived a trip in the washing machine around 20 years ago, but that it still works flawlessly to this day... Not even the lable came off!

[@awilliams1701]

This is the way to do it! You had a another video where you couldn't fix one and I suggested a PCB replacement. However I should mention On HDD Recovery Services (which used to focus on hard drives but does more USB and SD cards now) his fume extractor is aimed right at the PCB. Also for cleaning the PCB he puts a paper towel on top of the PCB then gets it soaked with IPA and then brushes it with a tooth brush. This lets the paper towel absorb all the flux.

[@eathenalexander2836]

Idk if you’re the first to do this. But it’s the first time I’m seeing it done. And it’s so amazing . I wish this catches on. Amazing work tronics.

[@Don-ii4vm]

Watching the work under a microscope is great. Seeing it without the microscope is all the more impressive as we can see the actual sizes being worked with. Excellent work.

[@danthemakerman]

I didn't even know this was possible. Really cool video!

[@ErkalEtruria]

You can move the components on any board to another board and they will function correctly as long as the board is manufactured in the same way as the one it is replacing. You only need the traces to to get to the other components. Someone correct me if I am wrong.

[@LetsPlayKeldeo]

Hey this isnt supposed to be a negative but you didn't go with gold fingers / ENGI I think its called but with the cheaper to just have everything coated in tin ( thus making your connections look silver) but sadly these are way more prone to make bad connections / beeing used up way quicker then gold fingers. Thus this replacment board won't hold as long as a original / gold plated board. I don't assume that the game will see as much plugging in and out action as it did when it was new but its something to keep in mind

[@mipi_game]

I laughed so hard at the lightsaber sound 🤣🤣 and yes I want to see the Gameboy video!

im blown away that worked tbh I had my suspicions that they would be married to the original board but guess not and that is amazing work good job Tronics!!

[@juvinious]

Recommend you not use HASL but gold plated finish. The HASL is definitely cheaper but it will ruin your gameboy cartridge slot over time. Additionally, you should have removed the battery before hot airing that board, you don't want that thing to pop and you end up getting hurt.

[@delivery2700]

Hey there! I use to see your videos couse Im an electronic designer over 20 years now, and love it. As well, I am a Video Games lover too, so your works mix both of my world and like your videos. That beeing said, I do recomend you to look up for thermal pad connections, so you dont have that big of a deal soldering some things like the battery, and also look up for Tear Drops, that will definly lower the liquid damage over pad connections making them more durable. If you wish, I'm up to keep in touch and help you with you future designs. I do it every day, and really really love my work, so will be my plesure to assist you. Great video as always! Cheers!

[@emmettturner9452]

Pokémon games are bootlegged so often that few will consider this legit with the wrong PCB. A donor PCB would’ve been the right way to go. Heck, it would’ve likely been cheaper and less work since you would’ve only needed to move the ROM with the right donor. The fact that originals have gold plated PCBs and are a dime a dozen means win, win, win, and win for using a donor.

[@Refort610]

[@jamesdavies686]

The HASL (solder coated) boards are actually a big no no for gameboy's. You want ENIG finish.

[@mjesticfalco]

@@jamesdavies686 adding into this, hasl will wear out after being inserted a few times as it scrapes against the console’s connectors, killing it eventually

[@rfmerrill]

9:29 For high-thermal-mass joints like that which are attached to something thermally sensitive like a battery (or a plastic connector, or insulated wire), I like to try and dump the heat in as quickly as possible to give it very little time to spread out. This means bigger, hotter iron tip, plenty of flux, and bringing a big old blob of already-hot solder over to plop onto it. It goes against the usual wisdom for solder joints, but the flux ensures it should all be OK. The solder itself is an important factor in the transfer of heat from your iron tip to the joint--if you put a dry iron on the dry side of a piece of metal, it won't heat up very efficiently. Gentle pre-heating of the board (to a moderate temperature, like 100-150 C or even lower) can also help a bit--it won't be trying to suck heat out of your solder joint as much. In fact, with this particular task, I might even consider heating the board from below, underneath where the battery is.

[@hydrolisk1792]

Great repair/rebuild!! However, when ordering card edge connector boards next time go with the ENIG finish. This puts a small layer of gold plating over all the vias, pads, and card edge!! This preserves the fingers of the game for a long time to come.

[@Nukle0n]

Would suggest getting ENIG coating on the card edge connector. And also having the solder mask cover just the slightest top bit of the card edge, just to make it slightly harder for the thin traces to get corroded.

[@LiquidSolutions]

Amazing job! Imagine the person who buys this game, opens it up to check the battery and is surprised to see a purple board

[@hairychest7865]

I would also invest in a better PCB cleaning system like a vapor degreaser to clean the boards. Q-tips and toothbrushes have a tendency to produce static and also do not fully clean the flux from the board. There is also a spray cleaner called "Flux Off" that works well also. Or if you prefer to use the IPA as you do. Install a small vacuum system to suck up the IPA/flux as you clean. Methyl Ethyl Keytone is a good cleaner also. And dries fast as well.

[@AlienX511]

Just a few questions because I’m a novice trying to get into electric repair. I’ve only ever really known solder in a wire form. Would what you’re using be solder paste? Also on your technique when you redid the legs of the chip did you add solder to the iron prior then touch it to the legs?

[@13hhall]

So, I know I'm a little late to the video, but, while renovating my home office and going through some old boxes, I found my oldest game cartridge. The Game that started it all, as it were. Pokemon Red for the gameboy color. It was the first game & gaming device that was 'mine". Not my dads, not my cousin's, not my friends, MINE. So of course when I also found my old Gameboy Advanced SP and the charger, I plugged it all in and tried to play a little. I got the "gameboy nintendo" screen, the next screen with the three copyright lines, the game freak screen, the quick battle screen, the game intro screen with the pokemon sliding on and off the screen, then I hit start, got the "saved game / new game / options" screen, accept there was no current save file, so I hit new game ... the screen went white, and professor oak came on screen like he was supposed to, then when his text box appeared on screen, no text appeared, the game froze, and it's like the game just started playing all of the sound bites written to the card. I heard the battle sounds, a couple of pokemon calls, some of the music from some of the towns, then after a few seconds of random sounds, it went silent or to a high pitched ring and never got any further ... Could this be a "re-flow the solder" issue? or is one of my chips damaged beyond repair? ... is there any hope for my dear old pokemon red?

[@lethe.archive]

when you were going over all the issues with the board i was half expecting you to go ‘well looks like this one isn’t fixable’ and having a 2 minutes video LOL.

[@rfmerrill]

6:34 I did see some flux on the board but it was definitely looking pretty dry when you soldered those chips down. If I wanted to do that one-and-done with the hot air tool, I'd definitely use a more powerful rosin flux or a no-clean paste like Amtech 559 or MG 8341. Also pressing down to make sure it's fully in place. Otherwise, I would much rather just put the component on the bare pads with no tinning and let the tiny amount of solder left on the legs stick it in place, then tack and drag solder to finish off once I have all the components on.

Great video as always, just a quick question, why so much flux? I've never had to use flux on any repair and especially not with a soldering iron as the solder wire has flux in it already! Means you don't have to do a whole cleanup afterwards and just less time overall, just curious

[@KingcoleIIV]

Flux will help the metal flow and remove impurities. Your repairs may work the way you do it, but they will not be as strong over time.

They should try to find some sort of padding to place on that part of the plastic cartridge that rubs on those small traces to keep them protected. when I worked for GE Aviation, we had material that would have worked perfectly. Also, I would have tack soldered opposite corners of the chips without solder on any other pads to make sure the parts sit flush and straight. then solder the other pins quickly with a mini wave tip. just my own preference.
