I can now save my game in Pokemon Yellow again after 25 years.

  Update: Now I’ve replaced the battery in Pokemon sapphire. Luckily since it uses flash memory my 25 year old save file is intact.

    Wait… can you confirm that these things don’t use volatile memory for game saves?

    • early_riser@lemmy.world ⁨4⁩ ⁨hours⁩ ago

      The only thing I can tell you is my save survived the battery replacement, which tells me it’s flash and not SRAM.

      Pokemon Ruby, Sapphire, and Emerald only use the battery to power the onboard clock, the saves are on flash. If you loot at the PCB you can see the flash chip on the left, it’s the one that’s not under the battery.

      It’s safe to replace the battery, but since the RTC will be starting from 0 again you won’t see time based events happen until the it catches up to the time stored in the save. If you’re not planning on starting a new game or fixing the save file using a cart reader and save editor (alternatively a DS with GBA slot and a flash cart) there’s no point in replacing the battery.

    Did the same on my Ruby half a year ago. Fun times.

  Joints look good! I would maybe look into cleaning the contact pads on the bottom of the cartridge though. It may work fine now, but those things can corrode and it looks like yours may have already started. A liitle preventative maintenance could extend the life by quite a bit.

  Side note on soldering - isn’t it crazy how easy people make it look in YouTube videos and what not? Like, they always just heat up and flow so perfectly and so quickly on the first try every time. I guess it comes with experience. It took me a long time to get the hang of it, and I still can’t do what those folks do. Anyway, your solder looks great. Proud of you, too.

  Your solder joints don’t actually look that bad. Ive seen much worse. But “works” is the gold standard anyway. You’re probably the only one that will see the board in person.

  If you want advice, it looks like your iron was either too cold, or you didn’t work fast enough and your flux burned up before the joint set.

  source

  • early_riser@lemmy.world ⁨1⁩ ⁨day⁩ ago

    It’s lead free solder. I think that affects how the joints look.

    source

    • WaterWaiver@quokk.au ⁨1⁩ ⁨day⁩ ago

      There are lots of LF alloys, some shiny some not. Your joints are fine, regardless of the alloy :)

      source
    • Romkslrqusz@lemmy.zip ⁨1⁩ ⁨day⁩ ago

      Mostly just visual in terms of shine vs matte. For the quality of the joint itself, lead-free has a higher melting point so you need more heat to keep it flowing nicely.

      Your joints will do what they’re supposed so, so they’re fine. Chasing perfection is just a fun minigame.

    Also it depends on the tip used for the soldering iron: those large surfaces have a lot more volume of metal that needs heating (plus you also need more volume of solder) so if one uses a conical tip it doesn’t transmit heat fast enough and you ended up with an irregular solder hill like that.

    If you’re use to soldering smaller components, doing something like that is quite different and won’t come out as well until you get used to its peculiarities.

    If you’re not at all used to soldering, that’s actually pretty good.

    Totally agree on “works” being the gold standard, especially on a something like that which isn’t subject to significant mechanical forces (like, for example, a push switch would).

    Yeah, you’re supposed to treat it like a popsicle, not a balloon.

• Ludicrous0251@piefed.zip ⁨1⁩ ⁨day⁩ ago

  FYI on the next one - they make CR1616 battery holders (like this) which allow future you to swap in new batteries whenever you want without additional soldering

  I figure if I’m gonna do it, may as well just do it once

  Enjoy having your old games back!!

  • SleeplessCityLights@programming.dev ⁨14⁩ ⁨hours⁩ ago

    I was talking to someone and they were saying that the solders on these adapters always suck and it creates more work. Is there any truth to that? I have 6 games I want to do this on.

    source

    • Ludicrous0251@piefed.zip ⁨13⁩ ⁨hours⁩ ago

      The adapter I shared has no solder except that which you put into it. It solders into place just fine with a little flux, I’ve had 0 issues in ~20 games from this.

      Be sure to clean your iron tip, I had a little bit of difficulty on the first one I did because I have had the same iron tip for like 10 years. A $2 replacement made life much easier. Probably also could have just hit it with sand paper. And double-check polarity on the connection points - watch a couple of YouTube videos to confirm you’ve got +/- right. I think it’s wonky on some carts.

      The ones that are soldered and often suck are the ones OP posted. Be sure to check the battery voltage before you install those ones because they use cheap batteries and duds are common.

      I’ve also seen people go the cave man approach and just un-solder/pry off only the battery (from the attached “arms” that connect to the board) on old carts and just tape a new battery in place but that’s an approach for monsters and psychopaths.

      I’m a bit foggy on the details but I think Pokémon Silver / Gold were a little trickier because the RTC changes the PCB layout and the battery is actually mounted on top of a chip, so space gets a little tight and you have to build a bit of a solder bridge up to the connectors.

  If you did soldering for the first time - your joins are pristine. They are completely fine unless you want to fulfill IPC-A-610 standard.

  source

  • BigDanishGuy@sh.itjust.works ⁨6⁩ ⁨hours⁩ ago

    Requiring 610 for your own repair of a game cartridge would be kinda ridiculous anyway.

    Besides soldering battery taps can be a pain. There can be so much thermal capacity in the taps (technically the cell, but). Combine that with an ordinary 35μm PCB, perhaps with some old school phenol board, and this result is some a newbie can be quite proud of. Heck, even if you’ve trained a bit.

• roadrunner_ex@lemmy.ca ⁨1⁩ ⁨day⁩ ago

  I’ve been so on the fence about attempting to solder, but it frightens me the idea of causing a little sparky fire.

  So, good on you!

    I’m blind (the device in back with the Freedom Scientific logo is an assistive magnifier). Both cooking and sewing are common skills taught in rehab centers for the newly blind, and soldering has aspects of both, being mindful of something very very hot near your hands, and having a certain amount of dexterity.

    Here’s what I did to build up confidence. I bought a bunch of perf board and resistors and I just started soldering the resistors to the perf board, that’s it. No goal other than to practice soldering. I had tried one of those beginner’s first electronics kits off Amazon, the ones with just an LED and a switch or whatever. I got discouraged because I messed up. So I figured if I didn’t actually try to make something, I could relax and focus on soldering technique. I was eventually able to solder header pins onto a Raspberry pi zero and even terminate a coax cable, and now I can say I replaced a GB cart battery.

      That’s impressive as hell, tbh. I’m glad rehab centers focus on such useful, otherwise seemingly inaccessible skills

      my dude you did this with major vision loss? i take back my earlier compliment. that’s not deserving of a smooch and a butt grabby. that’s deserving of a full on makeout and maybe a little hand down the pants butt grabby. make sure to ask yourself for consent first.

  • Godort@lemmy.ca ⁨1⁩ ⁨day⁩ ago

    It’s a useful skill to know, and it’s not super hard to learn. It just takes some practice.

    As long as you have some common sense(eg: dont set the iron down on something flammable) you shouldn’t need to worry about fires.

    source
  • CompactFlax@discuss.tchncs.de ⁨1⁩ ⁨day⁩ ago

    Fire isn’t a concern, really, the temperatures are low enough that it starts slow. Rest it on wood and you’ll have time to wonder why you smell wood smoke, then wonder why it’s inside, etc. before it burns down.

    source

    • early_riser@lemmy.world ⁨1⁩ ⁨day⁩ ago

      The real hazard is inhaling rosin fumes (says the guy who doesn’t properly ventilate his workstation). If you’re anxious about lead (I was) there is lead-free solder, though it requires higher temperatures to work with. As far as lead goes, the risk is from getting flecks of it on your fingertips and then touching your eyes or mouth. I imagine it’s less of a problem than it feels like in my head, but something something environmentally friendly.

  I so badly want to learn how to fix old tech like this. I’m fascinated by the tech repair YouTubers that can bring an old gba back to life. Someone I know has an old Pokemon Crystal with a dead battery from childhood and was broken up about losing their childhood save. I don’t think it’s possible to bring the file back but I’d love to get the cart working again at least.

  • imetators@lemmy.dbzer0.com ⁨15⁩ ⁨hours⁩ ago

    For the most part you do not need expensive JBC tools or some super expensive testing tools.

    If you plan to dive in, start simple with some USB soldering iron, multimeter and some cheap 20V labratory PSU. I found FNIRSI offers a USB-PD soldering iron with JBC tips for under $100 that is comparable to Weller 80W professional soldering station I got at work.

    The other part is just trial and error. Try with simple electronics or guides. Get the general idea on how things work. Most of problems are already solved. It is easy to find repair guide for some old gaming tech or how to chip your consoles.

    Have fun!

    It’s not hard. My Game Gears were broken and now I fixed 4 of them by replacing all caps.

    I got the Pinecil for soldering and it’s so easy to use and versatile. I got a couple of flux pens so the result looks nice and clean.

    source

    • ChocolateFrostedSugarBombs@lemmy.world ⁨15⁩ ⁨hours⁩ ago

      Pinecil, haven’t heard of that. I’ll take a look, thanks! Is there anything you used to practice ahead of time? Before jumping right into the actually hardware you were trying to fix?

    the hardest part of soldering is holding the damn thing in place. if you have something to clamp it, it becomes a hell of a lot easier.

    Yes, once when loose to confirm that the bent leg was the positive one, then again after taping it down to the board (measure twice, cut once). Then again after soldering it to confirm. I also verified that I can save now.
