The joy of being an adult with a disposable income... buying the toys you only dreamed of when you were a young kid. I still remember going to the video game store to trade my Genesis games for a few dollars so I could save up for some new release, and staring at the massive Neo Geo games on the shelf next to the Sega games. I wanted them. They were bigger, much bigger. All the artwork was fighting games. What was this mysterious console?
I've come a long way and I'm enjoying my Neo Geo ownership 30 years later. So much so that I have surplus Neo Geos. What the heck? Well, this handsome puppy is going to a new home where I hope it will bring the same joy to it's new owner as it does to me.
Before we send it off though, things need to be done. Lots of things. All the things. The full treatment to prepare it for another 30 years of Metal Slug and King of Fighters.

[@user-yg6tr1wm6x]

Hint. To unsolder bent legs, you can use a (very) large-caliber needle from a syringe (like one you use for flux tube, or maybe a bit lower diameter). You just take a needle, put it on the tip of the leg, melt the solder with a soldering iron and unbend the leg back into place. And another tip. To punture a hole in clogged via, you can use simple wooden toothpick - melt the solder and insert pointy tip of toothpick into via thats it. Thanks for videos. I really like to see this stuff.

[@davidwatkins6307]

You're very underrated I appreciate the videos you make and how you break things down I just turned 46 I had got me a neo geo system when I was like 22 from a game trader store at a mall back in the day and when I took it apart I wanted to solder some wires to that led light that was in the back and make a little puncture hole and hook it up at the top lol thank you very much for the video

[@BorderlineOCD]

It’s that inner desire to tinker. Once you get the bug, it’s there for good.

[@Lenskee]

That desoldering gun video montage sounds kinda like Sardaukar Chant from "Dune". 😂 Another easy operation by Dr. Borderline himself! Sweet! 😁

[@BorderlineOCD]

It was uneventful, but I’m always a little bit nervous firing up the system after a lot of work is done to it like this.

[@Brett_is_Veng]

i love the simplicity of these old consoles. New consoles have got way too complicated which makes them more fragile and expensive. None of these old consoles are perfect and most have issues of one sort or another but they do all live on far longer than the manufacturer thought they would. But that makes things so wonderful when you can get hold of a unit from your childhood or maybe even before your time. Love the vids, you have a fun hobby

[@oblivieon1567]

[@huldu]

Everything is so professional and well executed. I've seen a lot of similar channels and many of them do not come close to this. Many of them try joke around while working but it just gets over the top silly, like scripted. Most of us just want to see a professional do their magic while restoring/fixing old or new hardware and hopefully learn a thing or two in the process.

[@ModzvilleUSA]

Amazing work as always brotha! For those components with the legs bent parallel to the board, I like to leverage them up and snip them as flush as possible with flush cuts before desoldering. It's still a pain and isn't perfect but it helps quite a bit.

[@BorderlineOCD]

Thanks bro. I might have a bit more patience to do that than wet them with the iron and bend them straight before desoldering. Heavily edited and sped up video- the recap took just shy of a couple hours. Not looking forward to doing that again soon 😅

Neo Geo is such a rabbit hole. I've been a fan most of my life but gave up on OG hardware. I put a Pi3 into a Neo Geo X dock and couldn't be happier. It looks like an AES but man it's so much simpler. Great video though, for an OG unit it's awesome.

Anyone doing restoration on the console AES, the MVS (esp gen 1) carbon resistors sometimes drift out of spec over time. Lower quality ones exhibit this moreso than others, especially if the unit was stored in less than ideal conditions. Check the values if time permits. Metal oxide replacements are perfectly fine and tend to last a lot longer.

[@jeffgoodnough9704]

Looking toward my own Gen 1 MVS project, that's super helpful. Thank you!

[@crunchinjelly]

Love your vids. Binge-watched about 10 a few days ago. 😂

[@BorderlineOCD]

Glad you’re enjoying the content.

[@SparksNZeros]

one thing i found useful for stubborn through holes is when you use hot air to remove the chip, keep the hot air running but held slightly further away and use your desoldering gun to vacuum it out whilst its the solder is still molten from the residual heat

[@BorderlineOCD]

That’s a good tip. I’ve did something similar on the Crystal Xbox recap video for a couple of really stubborn caps but I had the board vertical in the holder, with the hot air from the back and desoldering gun in front.

[@spudhead169]

Your soldering is spot on. I watch a lot of folk doing this stuff and they do good and perfectly acceptable soldering work, but most of the time you can tell by looking it's been done by a 3rd party. Your joints look factory.

Maybe a useful tip: to desolder those folded legs @ 11:26 without scraping the board, use a soldering iron to heat the leg up, bent the leg straight before using a desoldering gun.

[@clocky4209]

I like the way you work on electronics! So well done, I mean like its well thought out, and cleanly done. Like how you made your own capacitor diagram, and marking where they are on the board before flipping it over, all the equipment you have, and its just so... wow!! I really wish I could have learned how to work on electronics from college the way you do, it would have saved SO much stress and headaches! Whenever I tried modding or repairing my own consoles, I would always do SOMETHING wrong, and it just made me lose confidence in my abilities, and I eventually lost interest and dropped out. Watching this makes me think that I could get back into electronics if I just didnt rush through things and thought things through! Where and how did you learn to work like this, man?!

[@37Kilo2]

When the legs of caps are bent over like that, I prefer to trim them as flush to the board as I can safely do with some cutters to make desoldering with the gun a little easier. A bit more work, but worth it in the end.

[@keithstone001]

A bit of advice if your desoldering folded over leads it's a safe practice to heat the joint up with an iron and use flat tweezers to stand the legs up before using a desoldering tool. That way you won't damage the board. BTW how the hell do you keep your table so clean and organized? I'm so jealous. Ten minutes into a project and I'm already loosing tools in the clutter I've created. Great show man. Love your vids.

I have a huge console collection that i have hung onto and collected all my life that have been in storage a few years now, i stumbled across your channel from watching TronicsFix and northridge repair videos and after watching a few of yours i decided to pull some of my systems to see if they still worked, i found a few of them are no longer working ,some wont power on, others had display issues some i have already repaired this week which was a virtual boy and 2 gameboys those where pretty easy i just reflowed the ribbon cables for now but i will prolly do the VB perm fix at some point, but my nomad has a really bright spot in the middle of the screen which i belive is just aging caps, my sega model 1 and sega cd model 1 still work flawless, i replaced the belt in my model 1 sega cd a few years ago and thats the only repair its ever needed, but my model 2 sega cd no longer will power up when i put a cd in it, carts work fine though. and i think my super famicom has a minor display issue. Anyway i havent done any soldering in very long time, the last stuff i did was installing a executer 3 mod chip into my xbox back in 2007 i think , i figured the time has finaly come to where i need to go threw and start recaping all these systems so i orderd me a digital microscope, and a new 2 in 1soldering + rework station and a few other things iv seen on this channel. im gonna practice on some old pc motherboards i dont care about first and evently start giving it go. Watching your channel has given me the confidence to finaly give it try as i want to pass my collection to my daughter when she is old enougf to appriecate them. Oh yea after watching this video i checked out my neogeo and it is the 5v model ( 3-4 board ) with a realy low serial number its all orginal and never been opened and is still working perfect but evently i want to do the audio fix on it so that was pretty cool to learn after watching this

[@BorderlineOCD]

Sounds like you got a nice collection. Great to see you getting into tinkering with it. Note: the audio L/R fix is only needed for the 3-6 revision motherboard. The 3-4 audio circuit has a bypass mod to improve it’s quality, but L/R channels are correct. Confusing I know but each revision board has its unique required mods/fixes.

[@turdpeterson73]

@@BorderlineOCD the audio fix im talking about is to replace components snk removed in the 3-3 / 3-4 versions which causes power hum to be heard, the 3-5 boards they put the Components back in, its just a couple Ceramic Capacitor's that goes on the back side and 1 Electrolytic Capacitor

[@adlorin]

What are your thoughts in regards to latency of the rgb bypass with the retrotink 2x, vs a simple svideo op-amp? I use svideo on my older consoles because it cleans up the image quite well and it doesn’t add latency like converting it hdmi does.

[@jamesdavies686]

Weird that the white silk screen marking for the caps is actually positive, I thought you put in some backwards until I rewound and checked.

[@BorderlineOCD]

Great minds think alike. I had the same thought. It was even confusing me when I was putting the capacitors back in. I stopped looking at the board and just paid attention to my diagram. Very counterintuitive.

[@BasementBrothers]

The guide from FirebrandX suggests optional 220uf 25V caps on the RGB lines to protect against voltage backflow. I added these inside of my system in place of the removed caps, but the end result is much less clean.

[@BorderlineOCD]

What does your end result look like? Is the image darker or do you just still see some jail bars?

[@BasementBrothers]

@@BorderlineOCD I don't think the caps themselves resulted in any noticeable difference. They're just there to create a more correct electrical circuit. By "much less clean" I just mean my mod work inside the console was not pretty. Results look good. I also grabbed CSYNC from the TTL sync in on the Sony encoder chip and attenuating it. The reason I put them in the console rather than the cable is because I use the same RGB cables for my Neo Geo CD and CMVS. Thanks for the professional quality, interesting video, as always. Your Neo Geo videos always make me want to go play KOF 2K1. 😁

[@sxixlxnx]

Great work, great explanation. I regret selling my AES to this very day. It’s now way too expensive for me to get back into. With that being said I might purchase a boxed console and SD cart one day but unfortunately the games are a no go for me now.

[@djrkzr]

I'm surprised that all you need for RGBBypass is only 3 resistors and not some tiny pcb with one of those ths7374 or 7314 reamps

[@BorderlineOCD]

There’s some interesting info on the RetroRGB post in the “oscilloscope analysis“ section. In this particular case it seems you can arrive at the correct voltage levels just by using resistors.
