More info: It appears that this thing is a NTSC to PAL converter used primarily in Hong Kong to make some consoles compatible with PAL TV sets. They are usually unbranded though. Thanks to Voultar, Aergan, FourX and GadgetUK164 for chiming in! Now that I know that, it's actually obvious, there were some tell tale signs: The crystal which, when divided by 4, gives you the PAL color burst frequency. And also the fact that I could see colours on my other screen (the one shown in video accepts both PAL and NTSC so this one wouldn't have given any clue)
I think I have one of these, converted to pal in the late 80s by the importer, and has stickers to say its pal on the box and console. It looks like it had oval sticker residue on the left hand side which could have been the Modders security seal, and to show it had been modded. 👌 Interesting to see the nintendo board inside
@@rollerxcore Isn't it! I asked quite a bit of people, they knew what it was, have seen some before but none of them has ever seen a Nintendo branded one.
Was going to suggest that, from the second crystal and logic chips. One of the chips starts with PAL something too. Interesting find. Unlucky with the fault though.
@@RetroClaire Yes but I already 3 people who offered to send me a spare board to fix it up. I have another coming that is faulty, it shouldn't be the same fault so I might be able to get one working. I'll probably accept a spare board from someone to fix this one but the shell is so beat up that I would have to buy a replacement shell (there are some nice ones but £90...)
Instead of going to the pin out for the HuC6270 you could find 5v and ground on the board [footprint] and then check those pins on the chip. It didn’t take long to look up but it still might’ve been a little bit faster to search the [chip’s footprint on the] board. :)
@@SLRModShop Oops. Edited to make it a bit clearer: “…might’ve been a little bit faster to search the [chip’s footprint on the] board.” Sorry about that!
Very cool discovery - never seen this little Nintendo board before! I bet its pretty rare! Pain those 6270's - they've been the fault more often than not on PCE I looked at. That Core one I looked at had a short just like yours did in this video.
Oh, I'll go watch that to see how you discovered it, not sure my technique is great to track shorts. It worked great in some cases though, I was able to find the source of a short just by looking at the resistance. No idea how other people are doing it though. I came up with that, who knows, maybe I just re-invented the wheel or just got very lucky.
@@SLRModShop Have you seen GameTechUS use a LeakSeeker tool to find a short inside a TurboGrafx-CD dock unit? It’s a very cool tool. :) I used the alcohol technique to trace a damaged Hi-Def NES after learning it from Louis Rossmann’s channel. Very useful!
@@SLRModShop I checked a few years ago and it was the same here. :( I did see a kit for building your own but they don’t seem to sell the assembled ones anymore last I checked.
@@emmettturner9452 Oh wait, I'm watching GameTechUs' video and how he describe how the device works, is exactly my methodology! Just in case it's not totally obvious in my videos (which I doubt), I don't have a proper education. just 3 years ago I didn't even know how to wire an LED. Man that feels great! I'm getting the hang of this thing! As you can see, I'm great at soldering but in repair I'm just using my available common sense, feels great to see that I could come up with a more than "not-so-shitty" way to deal with a short! The thing about "low current injection", I heard about it, but tracking the short (or at least its whereabouts) is something that I came up with. I feel kind of proud right now ^-^
@@SLRModShop That’s what made me think of it. :) Same thing, just wrapped up into a tool with fancy indicators and adjustments with enough precision to tell a bit more clearly than a ohm-meter alone.
I put an offer in on that PC Engine on eBay and missed out judging by your video I had a near miss as unless you can get that chip cheap it’s unrepairable. Still cool with that NTSC to Pal board fitted although it doesn’t look installed legit more like home install. Was really weird when saw the video and distinctive markings had to go back and look at the eBay listing again!
Someone is sending me some spare parts. Don't feel bad, I found a cool little piece of History in there but nothing really ground breaking. Without the Nintendo logo on it, no one would bat an eye. The shell is also dead for good, no way to save it so, I'll have to buy a £90 replacement... You didn't miss out, you dodged a bullet =)
@@SLRModShop yes and the good news is I discovered your Chanel by it so seems a win win all round. If I could of repaired it I was looking at Retrogamerestores PC Engine smoked transparent case and matching controller they look so 😎 keep up the good videos !!
@@SLRModShop Yeah, I don’t recall which changed first. We know someone has been inside so it is logical to assume they were probably changed and are not the original screws. Though that controller port is shaped like newer controllers I believe it is the older version. Some non-Turbo PC Engine pads had round connectors to match the round port on later consoles. Controllers like Avenue Pad 3 and Avenue Pad 6 stuck with the round port.
I have a TurboGrafx-16 with graphical issues and I expect it is the same problem. Most games show a black screen even though they are booting. If I let Blazing Lazers loop it one of the stages shows white sprites including the player’s ship which is just black/black for several demos loops before that stage so it must be something about that level’s pallet. I tried many games and I believe Victory Run was the only one I had that would show graphics at boot but the colors were still wrong. I reflowed everything and there was no improvement. My plan was to swap chips with a known-good console until I isolated the bad chip but I will return and look for an internal short like you did before risking my other perfectly-working consoles. Thanks!
@@SLRModShop Very! I have been enjoying your videos and learning a lot. Thank you! Hope my other comments have been helpful since I’m trying to return the favor wherever I can. :)
Over a year ago I was researching the NEC MK5060-A chip from my PAL-modified CoreGrafx. I found on NESDEV that it was also used in the Hong Kong version of the NES/Famicom. I made a few IMGUR galleries about it but I fear my comment will get filtered if I link them. I will follow this comment up with those links. :)
I can't see the follow up comment, did you made it? My channel should allow for links but the YT comments section is fucked up for a while now so, who knows...
@@SLRModShop Yes. I commented with three URLs. I believe you can find them as filtered comments using the desktop site but I can’t find them in the Studio app. :(
Here are the important bits of the URLs (add to the end or IMGUR’s top-level domain name): _slash_ a _slash_ AjyI8RL _slash_ a _slash_ YOrzWiz _slash_ a _slash_ fvByupN
Anyway, I could not find that chip being used anywhere other than PAL NEC and PAL Nintendo consoles. It seems NEC made the part for Nintendo and then used it for adapting PC Engine/TurboGrafx hardware. For PAL importers to have access to it in their modified consoles requires NEC/Hudson to supply a part that wasn’t generally available off the shelf. This strongly supports the idea that the PC Engine import market in PAL territories was semi-official and endorsed by NEC/Hudson despite them making the dedicated PAL TurboGrafx.

Early model white PC Engines had standard screws. They also had a different shape around the controller port.

what the hell
It's actually quite common in Asia apparently, although not always using Nintendo parts. Quite surprising nonetheless ^-^
