            ebay reseller here. thank you for doing the god's work, buddy! you heard him kids, emulation is just not the same. you must buy a console at 2x what it cost at launch from me. not sure if it's working though, I got it from goodwill for $5. but remember, that's the only real way to play the game. stop being poor and buy!

        These things are pushing 40 years old. Even if it was new still in box will cause issues. Metal will oxidize and capacitors can leak. The plastic will turn yellow and discolorize. Cleaning the contacts with alcohol is a good idea.

        It's not the joints that fail, it's on the top side of the board. The ribbon will rip off and it would be hard to see if it's just one connection that's gone bad.

                They take good care of their stuff and from a purely physiological POV East Asians don't sweat as much as white people so there's less sweat and gunk caked on controllers.

              Not at all. It's the bread and butter of low skill "modders". Imagine having no skills or training but being able to charge $50-$100 for 30 minutes work you can do whenever you want. I'd imagine such a person might run around screaming that the sky is falling and the only way to save yourself is to recap everything
              Also don't confuse "recap" with replacing a bad capacitor. One is good and necessary. The other is a tidepod tier fad.

              Based gore producer. It's not worth the time and effort to do things cleanly on a $5 console. Just dig in and rip a hole in the package using whatever you have laying around on the workbench.

                Preventive maintenance can be a good thing, but there are important things to consider.
                1. Is it preventative. Is the cap you're gagging to replace actually ever going to go bad.
                2. Do you risk doing more damage than good. For most people the answer is yes as soon as they pick up a screwdriver. It only gets worse once they get inside. If they don't rip up a pad or trace while desoldering they do it when tucking the radial capacitor they soldered to smt pads into some cranny. Popular "cap kit" mills actually sell kits like this because it's supposedly too difficult for the average homosexual to solder certain caps. I can't think of a better reason said homosexuals shouldn't be picking up a screwdriver.

              • 3 weeks ago
                Anonymous

                Hands down bad recappers. There are relatively few systems a bad cap will "ruin" it. It might not work correctly, or at all, but it's not ruined. Bad caps rarely rip up traces and burn holes in things. That's a lot more common with recaps, and exacerbated by the number of unnecessary caps replaced. This will only get much worse with time, because a shit job can take time to fail. A large radial cap may take a bit of shaking to rip SMT pads off a board. Same for balls of solder that break off and short something. The list goes on. All you have to do is look at picture of soldering people do here and on their home board of reddit so see this shit is rampant.

                this is why modern solutions exist like liquid solder paste that only needs a heat gun.
                is kinda dumb sticking to primitive solutions when most of those repairs can be done quite easy and more precise with modern tools (available on japan and several places more)

                >liquid solder paste
                Great for many things but it's far too expensive for poorfags. When you've spent your last $100 on a broken console on ebay all you can afford is a small coil of the lowest quality garbage. Also, "a heat gun" is the "primitive solution". And advanced being can solder a TQFP304 in under 60 seconds with a heroin spoon. Also, you completely forgot the whole part where you have to desolder the caps before soldering new ones. Surely a trivial step that you just forgot about because you've done it so many times.

                rate it

                Honestly 9/what I expected. It's hard to tell from the picture whether some stuff is sloppy solder or reflections, but there's plenty of visible slop. Looks like you also removed most of the base plates, which are there specially to prevent big caps from flopping around and tearing up pads. It's not a disaster. It might work. But personally I wouldn't power it up without thoroughly checking it. Especially the nasty parts, like around where you melted that chip. Fingers crossed.

            there's one gear in particular that breaks on all the disc drives, I had to replace it in my turbografx-cd. not hard to replace but I highly recommend putting a small piece of tape on the c-clip that holds the gear onto its shaft when you're trying to get it on/off, that clip is a tiny lil shit that will go flying.

            I can't say anything about flash cards, because I have never used one. But garbage graphics like this are caused when some parts of the rom from the card/cartridge cant be read and the cause in 99% is dirty contacts.

            quite likely. i mean this PCE is apparently NOS that was never even used before.

              All 8 and 16 bit consoles had external PSU as far as I know, it's just a matter of getting a AC Adapter that sends the correct voltage (which in the case of the pc engine happens to be the Mega Drive 1 AC Adapter)

        Yeah, /vr/ got some very persistent schizo who gets butthurt the moment someone plays on real hardware instead of emulating. Probably the same guy who pretends every CRT is a high-end mint studio monitor for thousands of dollars instead of something your neighbors gave you for free when they were cleaning out the basement.
        really weird guy with massive emotional issues.

      but he says it works with his Flash cart until he tries to start a game. that may suggest the Flash cart is at fault but he has to get some real carts to confirm.

        I can't say anything about flash cards, because I have never used one. But garbage graphics like this are caused when some parts of the rom from the card/cartridge cant be read and the cause in 99% is dirty contacts.

          quite likely. i mean this PCE is apparently NOS that was never even used before.

            Well that doesnt mean that much, I've had some ancient atari that sat on a shelf for a few decades blow all its capacitors when I turned it on.

              Electrolytic caps don't like sitting unused for a very long time, they tend to dry out. Using them keeps them fresh.

    and sometimes with hardware you have to do some mods/prepping to keep it working because the manufacturer was retarded or wanted to save 10 cents

      is this ever the company's fault? are they the ones who go like "yeah let's cheap out so we can profit", or is the the equipment manufacturer that simply cheaps out for their own sake?

        Nigga imagine designing a system you're gonna mass produce and not even testing thermals. Of course they knew the chips ran hot as fuck, they just didn't care. Even if you don't make the chips and just buy them to put them in your system you still knowingly sell a system that has a problem. Imagine doing the same thing with a car and putting shit made another company that you either didn't test or knew was dangerous but just didn't care

          The people who made the C64 assumed by 2023 we're gonna be in star trek holodecks and colonizing space. I doubt any of them assumed the C64 would at some point become a beloved collectors item.

            Anon, C64s were notorious for cracked solder joints, over heating ICs, and bad PSUs.
            I mean, I love the c64, but come the fuck on Commodore cut every corner they could with manufacturing and these things would die regularly even when they were relevant.

              Yeah, it was a piece of shit made to last a few years max, I think nobody back then expected them to be still around in 2023 outside of a museum.

                they got better with time, the C128, C64C, and Amigas were far better and more dependable machines than anything from pre-1985

              they were using really outdated 70s chip technology that had huge honking 5 um dies that got like a pizza oven when running and oldskool photolithography equipment that used contact stamping of dies instead of the more modern laser cutting method. this caused a lot of issues with low yields and wafer contamination.

                When MOS tried introducing 3.5 um they beefed it and had tons of self-destructing PLAs and TED chips. That was because the doping process was faulty and literally destroyed the aluminum traces on the dies (they applied too much dopant and the excess leaked onto the traces and melted them).

              they got better after the first 2-1/2 years but the early ones were definitely troublesome

              the VIC-II is a relative beast of a chip and is running internally at 8Mhz. it's actually too much for 5 um process and they should have split it into two ICs like with the Atari 8-bit graphics system to ease the workload on a single chip.

          The worst offenders of using known bad parts are actually car manufacturers kek. Look up a recall list for any five-year-old car or older.

    I dont know if it’s related to this issue but the PC engine is at a point where some caps are dying, have you checked inside the unit?

    They should have put a proper heat spreader on the VIC-II ala the TMS VDP instead of the retarded attempt at using the RF box as a heat sink.

      Bit paranoid tbqh. The VIC and kernal ROM are the only things where heat buildup is that significant.

        the kernal ROM in VIC-20 does get a lot warmer than the BASIC or character ROMs and i don't know why that is. apparently it's a common failure point for this reason and should be sinked.

          My understanding is that MOS didn't quite standard mask ROMs they were a slightly customized design that had some kind of pre-charger circuit to speed up access time.

        duo-r does look like a toilet, but it's super reliable to the point it's almost worth it.
        too bad the original duo is one of the least reliable consoles because it's the best looking one.
