I'm going to have to enjoy this ep later, but I just wanted to thank you Vince! I got up the courage to fix an intricate little battery wire in an old Olympus Pen FT camera. And even when I created another problem, I was able to fix that too. Your honest and methodical process gave me the guts to go for it myself!
Another great video, would be interesting to see if a controller can somehow be wired into this so it’s acting more like a console, would probably make game play easier and no risk of hitting the reset!
Great job Vince! =D There's no way that's using any Sega chip - it looks like an ASIC (cloned hardware). In any case, the sound is pretty bad (on Sonic - compare to original Megadrive sound - it's very different to how it should sound). It's very similar to the AtGames Megadrive handhelds! It's just a modern clone basically! That inductor looks related to Chroma (colour may not be as good as it should be without it). You could try fitting an inductor over there and see what difference it makes! A real shame the screens aren't easy to get, maybe someone will point out a source of replacement other than that seller in Russia. I have the old screen from an AtGames one that looks similar, I will check it later.
@@Mymatevince An upgrade or mod video where you try to make this knock off handheld be as best it could be would be an interesting watch and a slight humorous jab at mod videos. I reckon you could fetch a pretty penny for this with an IPS display, tactile buttons, case repaint ;) and as Chris mentioned have a look at installing a chroma/luma inductor. But in all seriousness, nice job Vince.
This one seems to not be related to the AtGames ones because the incorrect sound is different - instead of being out-of-tune it's distorted and incorrectly mixed, with the PSG being louder than the YM2612.
8:17 In this table "one" indicates connection to positive voltage and "zero" is connection to ground. The middle solder pad is the signal and the two next to it are ground and positive voltage. The two columns are for NTSC or PAL configuration. 9:55 Always add flux before melting old solder (with an iron, as opposed to hot air)! It worked out alright in this case but that's a rule I pretty much never break. 10:31 To create an intentional solder bridge, you want the solder blob to be partially molten and partially solid. I usually do it by using a small tip, and moving the solder across with just the very point of it and drawing it away gradually. Lower temperature might also help 16:02 Is it possible the pinout is actually the same and it's just the numbering that's reversed? That does happen sometimes where you have two products that are compatible with the same signals in the same physical spot, but just numbered the opposite direction. 22:54 The inductor is probably part of a delay line or bandpass filter for the composite video encoder. You might just get reduced video quality if it's missing. 25:03 As others have mentioned, it's probably using one of the chips made for the licensed plug and play systems like the ATGames or Radica. The real sega genesis/megadrive integrated chips from the late 90s are huge 144-pin or so QFP deals, would almost be the size of that screen..
Honestly such a great fix! Nice fault finding and also I ordered a few different cables for a project for the same reason you made one. I just couldn't figure out the right order for the video. It was great to see you make the cable
Well done Vince you have come so far from your early videos I have watched you since the telephone man, but I don't think you would of picked up that fault when you first started your fixes so shows how far you've come you should be proud and keep it up. Love watching the videos.
Just so you know I have seen things on wish etc where the image is the mirror of the actual product cause of the camera they used. Just a heads up it seems weird they'd make a screen with the exact mirror image pin out
love this one Vince. it brought back some old memories of me and my best friend playing golden axe at pizza hut. we used to go there everyday after school and buy some pizza, root bear and play golden axe for hours. thanks for the memories.
So, you're saying the pin description is flipped and so is the numbering? That would mean they're the same, flipping twice is the same as not flipping at all. IE, D0 is pin 1 on the first description, pin 40 on the second description but they're actually the same pin on the ribbon because one counts from left, the other from the right when the display is the same orientation... Given that you're extrapolating your pinout from the russian listing we can't be sure but it does sound WAY too much a coincidence that ALL 40 pins match exactly, just mirrored.
I agree. Also notice that on Aliexpress listing pin on the left is marked as a pin1 while on the "official" manufacturer's website that pin is marked as 40. It means his number 40 is where number 1 is on AliExpress. If pins 1-5 and 40-36 do the same the screen is the same.
i agree, if you go pin for pin (reversing one set of numbers) they are the same, save a small difference, like pin 36 here, 5 on ali, one is called C4M, the ali one is listed as C4N, but the non connected ones are all the same.....
Looks like a failed pal to ntsc or vice versa conversion. I would think the 5/6 setting would be for 50/60 mHz and they just bridged it too far. Also you could just leave out the reset button and use the power button to reset it.
You'd be right... this was one that WAS working, then I broke it , and thus it ended up in the box of treats for Vince :p As for the screen , that's annoying, as it wasn't broken to begin with, I wonder if it got smashed in the shipping process :(
Hey vince, I was wondering if you ever found a replacement screen for that sega game gear that you modded a while back? I did a few with the clone kit and in one of the kits I got a bad board that only outputs video to the vga port. I don't know if both kits use the same screen but I got a good screen that I can't use. I could make a game gear consolizer with the bad board but the screen is just sitting around collecting dust. These kits the screens are separate if you can remove yours and get me the pin count and model numbers I can check it against mine. I'll ship it to you if it'll work just to see you revisit that beast.
That's a cool little device. I am now looking for one but only see the cheap ones without the slots lol. Shame you can't fully fix it but honestly if they can be found would it be logical to spend about the same amount of money on the screen as a entire device
Great job! What if you bought that screen with the reversed pins, and got a length of 40 pin ribbon cable, soldered that on and then wrap/bend it around so the correct pins line up.
@@RestoreTechnique I watched some of your videos and I was blown away and subscribed .. so much effort in camera work and editing is amazing. so far I liked the handheld game restoration the most
Hi Vince. This comment isn't related to this video but to some of your older stuff and I was wondering if you could spare 5 minutes for some advice? I have just completed some renovations at my house and moved our bt master socket and replaced the faceplate. Our current drop wire comes into the front porch and into a box, whereby the orange and white wires (the other wires are black and green) are crimped to a new piece (of the same colours) which ran to where the old BT socket was. Since I moved the socket, I was looking to replace the piece of wire which ran from the box to the master socket as it is old and covered in bits of peppledash and silicone. Which of the new cable configurations would be best to connect to the old orange and white connections currently in the junction box?
These will be a genesis on a chip, same as all those NES and Megadrive clone handhelds, interesting that it plays carts though. Not real hardware and inferior to good emulation but fun to use anyway.
Sega also released their own first-party portable console, the Mega Jet and Nomad, depending on the region of the world you were in. Quite a bit larger than this, but a complete, fully functional, portable console that even supported external controllers for 2 player.
I think pacman has issues with 6 button controllers. In order to play it normally you need to switch to 3 button mode by holding mode while turning on the console. Not sure if it would work with this clone.
Maybe the picture of the ribbon cable was taken with a phone in mirrored mode. If you wrote to the supplier and asked them to verify the picture, it may be what you are after.
With Chroma and Luma pads, I wonder how it would look hooked up to an s-video input. You'd need to solder directly to those pads, but that isn't that big of a deal.
15:47 Is it just me (just double checked..) or is the pinout reversed TWICE, so the screen should be the same.. i.e pins 1-40 are marked in reverse, and the pin outs are also reversed, so the data pins are to the right extreme (when facing the white back) on both screens (broken and aliexpress)? Should work right? Also kudos on the TRRS job.. ive been trying to fix headphones more times than id like to admit, and i always keep ruining them at this point...
I buy from Russia all the time, its like using Sendico and can be a bit nerve wracking but these places in Russia are used to talking with people in English and other languages so maybe an email to them. Russia Post is surprisingly quite swift and quite cheap too, in the years I have been buying Soviet watches etc haven't had one go missing but then the slightly higher ebay postage cost is apparently a "little" earner to pay officials to ensure your thing isn't stolen in transit by bandido's.
Love the fix, what's the name of this console? I wanna find one, edit; well if you ever want to find a 4 pin plug with video and r/l audio, try a Nokia N900 video cable, and get a adapter
Call me paranoid but can't help thinking that someone deliberately soldered that to deceive, knowing that the screen is broken. I've noticed plenty of suspicious sellers selling broken devices without hard drives, claiming they have no means to test it. Selling devices without cables etc. The world we live in.
It was ME :-p I tried to solder the pins across and do a 50/60 hz conversion, as I was using it to test cartridges, and was getting fed up being told I was using a game from the wrong region. Upon taking it apart, and soldering.. it stopped working, but the screen was OK, I am thinking that th screen got damaged in the post, as I am quite sure I didn't smash it while dismantling / putting it back together :p
I may be misunderstanding but... Isn't that screen compatible? If the leftmost pin on aliexpress is pin 40 or pin 1 doesn't matter , it's still the first 8 pins on the left which are data, just on yours the numbering is going from left to right rather than right to left?
vince there is a lot more to this its had some work done to it there is a lot of corrosion on the board & the screen cracked when the internal battery expanded
Hello form Finland, i have an wierd issue with my msi gaming laptop, the fans starts and light come but noting at the screen also the fans goes full rampage mode for a second then just goes normal, also the gpu chip isn't going worm only the cpu. Is it possible that the prossesing chip is gone bad? just wondering coz the ram also dosen't get any power. ps sorry for my bad london :D
Nah It’s the Master System sound chip that is too loud, the YM2612 is too quiet! But is it a TCT-6803 problem or just a bad clone? TCT-6801 in the Mega Drive X sounds much better!
@@SproutyPottedPlant I might have said this in response to one of your comments already, but it's not a chipset problem, it's an analog circuit problem, one which should be fixable by swapping out a few resistors, then running a homebrew tool, MDFourier, to ensure the audio balance is correct (test tones played through the 240p Test Suite on the console which are then compared with a reference recording from a known good MegaDrive). You can even use this to match the frequency response if you so desire.
Those screens could work fine. Just rewire or flip the ribbon cable. Not that it's worth it. Cool toy. I buy stuff like this at thrift stores whenever I find them.
Hi Vince Hope you don't mind. I have sent you a package to your P.O. Box. Its currently in a car from Spain. Then will be posted. Its a quite sad PS4 I got at a rastro (Flee market) for a few euros. Maybe you can fix it or use it as spares
Hey Vince! About the display you found through google pics - ulecom.com.ua/p943239632-displej-registratora-falcon.html Its some sort of webshop in Ukraine, that sell different dash cams and parts for them, old motherboards ets. Not sure about selling outside of the country, you can try to write them ulecom.com@gmail.com, they should speak english, since selling electronics. Price listed on the page is 210UAH (grivna), its around 7 euro + delivery.
Probably the firecore SoC, fairly bad emulation of the original Motorola chip. AtGames was using that in the official licensed sega minis, they are so bad it's offensive to anyone who played and loves saga MD 😂 especially the sound, truly truly awful.
