In this installment, I'll show you trade secrets that I devised many years ago for PS1 hardware. The technique's demonstrated here are applicable for models ranging from the SCPH-5XXX all the way up to the SCPH-101. This is NOT a tutorial, but just a brief overview of how I operate when working with this hardware.

[@Voultar]

Mayumi over Multi-Mode, always..

[@iJo09]

Voultar why? What is the advantage of mayumi?

[@nondescriptstraightwhitema6138]

Voultar I need some help with this. Back in 2002 a buddy of mine who spent way too much time in Korea with the army brought an original PS1 home. It had a mod that plugged into the serial port on back and just stayed there it was about the size of a pack of cigarettes his PS1 played DVDs... what was that?

[@Kurokami555]

i would also like an answer to this as what ever that was sound interesting

[@MrPete1985]

Was probably a VCD player, they used MPEG1 and could be written to CDs. I burnt my share of VCDs before I could afford a DVD burner

[@Haldrie]

It could be the fact that the Mayumi chip uses the PS1's own internal clock signal to drive the timing so it's more accurate as long as it's not getting any interference when the likelihood of that happening with the way he installs those chips is very minimal. The Multi-Mode chips use the PIC's own internal clock which is accurate enough to work most of the time but can fail on rare occasions forcing a system restart to get it working again as I have had to deal with for my MM3 modded PS1s that I installed. I use MM3 in my gray systems mostly so I have the ability to disable the anti-mod protection and the chip itself to test certain things. My chip installs aren't as clean though as I like to put the chip in a socket that is easy for me to access so I can swap out the chip if I need to like I recently did to see if a chip I had flashed was working before I installed it in another console. I rarely install chips for others but I am doing this most recent chip install for some kids next door which is still going to be a surprise for them but I'm still waiting for a new memory card to arrive so they can actually save their games once they get it. By the way Voultar I only recently found your channel and I'm liking what I'm seeing so far and will consider some of your methods the next time I do a mod chip install. I destroyed 3 PSOnes trying to install a chip using those "other" diagrams you mentioned mostly due to my lack of soldering skills but I did finally manage to get a working install with two of the wires being soldered directly to the drive controller chip so that gave me a nice confidence boost especially when I'm only working with a cheap 30W iron I got from a local hardware store and who's tip really doesn't last very long before I just can't get it to hold solder or heat long enough to do what I need to do with it but being cheap it's easy to replace when that happens.

[@michaelsworkshop9031]

You forgot both the two-part epoxy AND the bubble wrap.

[@SirJohndill]

Beautiful clean install mate, very well done!

[@Sayajiin2]

Love your video Voultar, Modding Pron at its finest art!

[@prmotorsports]

Just started watching your vids and dam your a master at what you do meticulous work is hard to find nowadays keep up that great work

[@T0phen95]

I am going to be doing a PSone MM3 mod here in a few days. I was looking at the diagram for the SCPH-50xx series and I remembered this video. The diagram looked horrendous, I'm glad I found this video again. This will be my first actual soldering job with a real soldering iron. And this is also going to be on my childhood PSone. I know I'll get it right thanks to you!

[@emmanueledettorre2087]

was waiting for this for a long time

[@devlin25711]

Great videos , I honestly know nothing about any of this but it’s fun to watch

[@dlang6487]

Another great video from Lord Voultar!

[@frankstrasser6108]

Very clean I like the music during the soldering too

[@frankstrasser6108]

Fill Royy yes I have the game it's one of my favorite shmups

[@MellowGaming]

Cheers for that. Shazam failed me when I tried to find out what it was.

[@devsfan1830]

Saw your newest dreamcast video and have been walking through your back catalog. I had an MM3 chip installed on my PSone and while it technically works this video has made me want to re do it as neat as this is. Then saw your pinned comment and after looking up what it is and why I will be using a Mayumi this time as well. Thanks and keep the videos coming!

[@robertrijkers4923]

when i modded the old playstations there was no youtube to learn from...would have been so much easier ;p soldering with fat..no flux...broken iron tips... too much heat when knocking off those tiny resistors when you accidentaly touch them..great times

[@rynnetaylor1277]

Nice to know that I am not the only one who has done this. Sure feels good making the PS1 work again afterwards too.

[@Salanto]

I came for hot glue and bubble wrap... I am disappointed to see the proper way of soldering! /s

[@matzo33333]

What you say about practicing with fine pitch soldering is absolutely correct, but many people will be afraid that they'll mess something up when doing so and ruin a working unit. What I recommend, is to find some free or cheap broken electronics to practice on, so if you mess up, nothing is lost. Old car stereos are great for this, they have lots of SMD chips to practice on. You can also sometimes find bulk lots of old PCI cards on eBay, which also have SMD components, and if the lots include LAN cards, the option ROM sockets offer the chance to practice desoldering DIP chips.

[@TheFritoNinja]

Finally someone who can solder, teach, and speak eloquently.

[@christianmallett8633]

Wonderfull , a piece of art your skill are, i remember doing My first and last onechip on a PSone , i burned like 4 chips (the one time burn type) and only one worked , all because My laptop wasnt suppling enough power to the serial Port so the chip didnt burn correctly, the last chip i burn it on a PC and it worked. I struggle , i was a newbie, but had little solderin skill and in the end it was all worth it. I still remember the first time i booted a copy of crash bandicoot and i almost cry XD. THANKS , like your vídeo and brought so many nostalgic memories. I Wish a was a kid again. Note : i also owned the original crash bandicoot Game.

[@im.a.nickel]

Slipping of the wire under the IC legs at 5:55 was way too sexsual.

[@frankstrasser6108]

BlowMeWonKenobi almost nsfw

[@nocturnal0072]

frank strasser actually NSFW.

[@Felipe_1930]

Splendid work, thanks for sharing! Now I'll have trouble sleeping until I undo my Mayumi install, replace the DIP-8 for SOIC-8, use breakouts and less wire, but thank you very much! :)

[@EngineerIsSpy]

Nice clean install ✨ From the service manual, looks like IC304 pins in order of solder are: 44 - XLT 02 - VDD 11 - VSS 19 - Door 14 - OSC1

[@Xitrial]

I'm really just watching these videos because of the beautiful soldering job, not because I want to mod something.

[@javiles2331]

Awesome clean job!

[@dcfuksurmom]

This is a very beautiful mod, there is only one thing missing, and its something every modded console needs, LEDs.

[@gaboaaa23]

hello, ive removed the mod chip in my pal psone console. The psone now want start my original ps1 pal game. Its goes straight into the cd player menu! What can be the problem? Now i cant run backups and originals as well! :(

[@gaboaaa23]

hey, i have a modchip in my ps1. if i want to desable it is it enough if i only cut one wire?

[@that1crzywhtguy]

Did you program this chip yourself? I'm wondering if there is a place you can buy these mounted on PCB like that. I just see the bare chip everywhere.

[@Fille-lj1qv]

thx voultar,exellent tips,i just buyed the desoldering kit for smd like you have,but is there a vaccum desoldering gun in that price class thats do a good job for electrolyte caps?

[@dylbob9000]

when you have all that excess wire coming through the vias did you trim to length and then solder or did you solder as is, using the solder to burn away the cladding and then trim?

[@Voultar]

That's the wonderful thing about Kynar insulation. It's heat resistant, so when you apply heat to the jacketing, it's only going to remove material that comes into contact with your tip. What I like to do is just make a circular motion around the 1mm+/- material that potrudes from the via until the jacketing is stripped. I then solder and trim it up a bit. I couldn't figure out a good way to show that on camera because my damned hands were always in the way of the shot.

[@login0false]

Voultar Your habds aren't damned, they're f-ing golden. Also, where do you get these sick tunes? My playlist craves them now

[@f6y7t5]

I love the cheekyness

[@MrMario2011]

That's beautiful.

[@GS.record.studio]

oof first comment

[@alex_mula]

Such an inspiration.

[@maxabeles]

6:20 dayum, props!

[@rynnetaylor1277]

I can't believe you only thus far have 1.2K subscribers. You are obviously the best/one of the best at the art. I am a career master auto tech and I insist on quality, nothing but. People are super loyal too because of this. I like your style amigo. To me the "art" of sms is like learning a kata. Learning how is quick, but technique and grace only come with a bunch of practice.

[@OjStudios]

Quality over everything. I like things to last too. I'm just a humble dude fixing bicycles for a hobby but I've gotten many loyal "customers" that have moved over from super expensive crappy quality techs on this city. Rock on quality!

[@chiriga_]

You are a awsome youtuber

[@MasterChi48]

Love the clean work you do on this channel and i couldn't help my self but to try your metheds out. Tried the methed.... and failed. Way too advance for me (for now). I hope to see more content from you.

[@jdom2006to2012]

I might have a project but would you or have you ever meased with a panasonic 3d0 I have one but its for a arcade from the 90s that id like to see up and going.

[@aaronlobato5268]

I am new to soldering and working with boards. I have put a region free chip in my ps1 slim. Do you have introduction videos because if I'm going to try I want it to be as close as possible to your end product.

[@BreezyKun]

What is the fluid you're dousing the board with before soldering? Rubbing alcohol?

[@ssssahek]

Can you answer a few questions for someone who’s been soldering for a long time but simply sucks at it and can’t seem to problem solve it well? I have flux, different sized tips, temp adjustable iron(a cheap one). If I’m having problems getting my pins to stick to the chips pins like yours do what’s my problem? Flux is down. Wires are tinned. Is my iron too hot? Am I not heating the chips pin enough? Am I moving too much? Is my tip too big or too small? I attempted installing an mm3 on a psx and immediately lifted a pad. So now I have to go to the chips pin and I want to do what I can to right my previous wrong.

[@Pertamax7-HD]

Super sir

[@peccamecha]

I may be wrong but it looks as though you've tinned the end of the wire on that first connection. This is something i've never seen and will be trying out

[@skuartle]

can you make a video from the xbox classic version 1.6 mod chip please

[@prestoncooper3502]

Killer Video

[@davepascual39]

I watched some of your modding videos. You've got LVL 99999999 soldering skill. btw what is that liquid thing that looks likes water you squish before you soldwr?

[@ricardo77773]

That is Liquid Flux or No Clean Liquid Flux.

[@Laura_M-16]

YES! That's a proper PS1. The chunky gray unit is a PSX.

[@andybufoso4636]

03:21 name of the song please (i know its not "deruda sandstorm" ;))

[@ablativeimagery]

Thunder Force IV FTMFW! \m/ Although, if I soldered to that music the outcome would be the most atrocious mess...

[@thejorde5440]

Thunderforce rocks! Literally!

[@AmpliFreQuency]

I KNEW it sounded familiar, but just couldn't remember exactly which game it was. Such a classic!

[@sharpsharkabcabcabc]

Is it possible to mod psone booting gameshark menu catridge? I saw one before but i dont know where. It called zippy

[@samson7point176]

Can you give advice for which tips to choose for the iron?

[@Voultar]

A lot of people will tell you to buy the smallest tip you can (for when doing this sort of work). I don't believe in that. The smaller the tip, the less thermal mass you have to deliver energy into the point of contact. Look at the tip that I use, for example. I use a large D type (flat blade) tip. If you're beginning to learn how to solder, the standard "conical" tip is more than sufficient for general purpose use. Everyone has different anatomy. Find what you're most comfortable with using and that you can articulate/maneuver well.

[@steveholvoet6058]

It's not about the tip, it's what you do with it. 😅 conical tips should seldom be used. Chisel and bevel tips, good flux and some practice is all you need. If you really want to get into micro soldering a bent conical tip might come in handy on occasion.

[@iCach0]

"Masterful"

[@nickmueller2883]

It's just that simple!

[@travisshipley2609]

Show us the ways of Neo Geo AES modding Lord Voultar.

[@Voultar]

It will be did..

[@travisshipley2609]

Prepared to strap on

[@davidkenyon5444]

Any place in particular to buy these mod chips?

[@GoatOfTheWoods]

please do more vids..

[@rafhaellprado3038]

Perfect!!!!!

[@lukealexander3639]

What guage wire are you using? And it's enamel? Thanks

[@Chris-tx9ou]

It would also be nice if you done a tutorial step by step which will help others learn from your skills to develop there own.

[@mkw050791]

This video is great but this music is amazing! I know it's from a Thunder Force game, but who is doing the cover of it?!

[@matyf_]

@voultar what's that liquid you use for soldering?

[@notman2k7]

Flux

[@AJFazz1984]

A random question whats the music you used?

[@youngcavesex2764]

Thunder force IV theme

[@zombiezedtwin12]

Hey im having trouble finding a preflashed modchip for a psone scph101 any help would be greatly appreciated

[@drac0nisw0lf]

I've never modded anything so this is all still new to me. What is that liquid he is putting on there before he solders the wires?

[@notman2k7]

Flux

[@anthonyleedickinson3491]

How about the mod on the psone where it gives dual bios action replay play without the port on the back. I have seen on eBay going for stupid money.

[@TheKeaos]

What gauge wire are you using here?

[@anthonyleedickinson3491]

hi does anyone know wiring for sst29ee020 to add flash memory direct to motherboard of ps1s without paralell port on. ive seen on sale before now but would like to give it a go.

[@ThinkBeforeYouSleepYT]

3:17 My hot glue is ready.

[@nitrax8629]

5:58 Wow, routing that wire under the chip was neat. Unfortunately, I don't think that is possible on later board revisions - they have a much thinner chip here that also integrates the memory to the left on this board.

[@toyd3sert434]

A master at work

[@almostdarkslide3851]

Is the solder splash near the writing [IC106] sony's fault or yours? I can't see it very well, maybe it's supposed to be like that? I used to mod ps in 1998, I started with a wood pyrograph, ah the good old times ;-) I remember charging 70$ for a mod, paying 1.50 dollar for a modchip. That was a really good ROI! nice job anyway!

[@nzitguy]

What is that theme music from?

[@MrMoonglum]

Please do a ps2 next.

[@WellBeSerious12]

What was this mod for?

[@devlin25711]

Again , I know nothing about this so I’m sorry if this is a dumb question but what exactly are you doing ? What is the benefit of doing this when it’s all said and done ?

[@Junkman444]

Watching a master with his craft and doing quality soldering and wire routing without installing rat nests (or gobs of hot glue) into game consoles. No one knows exactly how old Voultar is since his soldering is timeless.

[@boogiemanspud]

Is it just me or is the chip backwards to the adapter board? Hole 5 on this video looks like it should go to pin 1. It looks like the chip is upside down, not that it matters for instal, but hole 5=1 hole 6=2 hole 7=3 hole 8=4 and so on.

[@boogiemanspud]

Also, in case anyone tries this, there is a wire on pin 13 that isn't specifically said or filmed. I know this isn't a "tutorial" but hopefully this info might help someone.

[@RageUnlimitedLTD]

Isn't interference still a thing? Seems a bit dodgy to be running wires under chip pins.

[@Lilin-wc5hs]

what song is the first one ?? :O

[@meanmole3212]

What's that liquid you apply before soldering?

[@louskunt125]

Flux

[@macpclinux1]

So what exactly can you do after this? Speed up and slow down? Like i don't see what you'd do on games that are so simple and straight forward

[@notman2k7]

Play games from any region as well as play backups

[@gabrielmanarte6809]

what's the chip you're using there?

[@segasonic9117]

Goddamn, that is amazing. I wish your videos were around when I started my modding journey in 2013/14. You should charge a fee for your videos. Soldering teaching at its finest!

[@saionteller9427]

Could you try with a nintendo DS or

[@SDLearmonth]

Not that I expect a reply from you, as you seem to be a "figure it out yourself" kind of guy, but where how can someone get their hands on that pcb with the Mayumi mounted on it? It is only sold as a bare chip from what I can find...

[@Voultar]

Very simple. 1) Buy a SOP to DIP adapter (SOP8) 2) Buy the SOIC8 version of the 12c08/9.

[@SDLearmonth]

@@Voultar A reply! Do you mean a PIC12C508A chip? I can find very little (and conflicting) info on what PIC to use. And what's the difference between a SOIC to DIP and a SOP to DIP adapter? Thanks for helping the small fry out man

[@infinity2z3r07]

Strap on fools!

[@cobradadelectric6034]

i tried to install mm3 chip to my psone last night my first job ever the psone fired up for bout 25 secs then went black screen and now thats all im getting is black screen please any advise

[@Voultar]

Investigate for solder bridging around the MECHACON (Drive controller chip that you see me soldering to) - Investigates pins 3, 4 and 7, specifically.

[@ifrit05]

Came for PSX modding, stayed for Metal Squad.

[@nemesisnine3297]

Why does my PS one keep blowing the fuses after a failed attempt to shorten the wires in a successful mm3 install?

[@BMR86]

I tried this and I DID NOT use my noggin like you said... now I think i have an aweful install and pretty much a dead console... sad day for me... but hey! I learned my lesson....

[@mohandmohand2047]

Motherboard mp 41 (2) digram for chip 12c508/p 04 HAM

[@MobCat_]

Mayumi v4 "Voultar" installation diagram for SCPH-900X i.imgur.com/oZIgeR2.jpg This hasn't been 100% tested yet so use at your own risk (In my probing sometimes pin8 would probe the same as pin1 O.o?) Sadly 900X and 700X are all the ps1's have on hand right now and im to lazy to remove the RF shield to do a diagram for 700X. Maybe later if people really want it. Also if you super want to show off you don't have to use the solder pad for pin5. You can follow the trace back to the cd rom controller package and solder your wire to the back or side of the pin after you thread the wire underneath all the other pins

[@FolksFox]

What's that watery liquid he's pouring in every now and then?

[@InvictvsNox]

What's the purpose of this mod?

[@cordelldarkling3190]

I’m glad that you know that we came just to watch you solllllder... I’m not even the least bit interested in what you’re doing :| or why

[@PalominoBlueGames]

Did you say "Strap on"?

[@consolemaster]

If there's a need to use glue, what about electrical tape?

[@Penfold8]

You can use a small amount of super glue to anchor several wires together. You really shouldn't have to use electrical tape.

[@Jdmboi17]

I too would like to know what this mod is for. 🙁

[@im.a.nickel]

Seeing as there is 8 wires most likely MM3 Modchip.

[@Voultar]

Ew Multi-Mode 3. No sir! :D

[@undamned]

It replaces the PS logo at boot with a crappy MS Paint pic that says "VOULTAR" with fire barrels and guitars scrawled all over the place.

[@mtoad]

Which chip do you recommend for PS1?

[@Bemijaminji]

Where might one find a reliable place that carries these?

[@cosmickatamari]

Apparently 7 people like hot glue!

[@f6y7t5]

45 now

[@markusTegelane]

A lot more now

[@CreativeSam-cw9sh]

Tidy work, but you missed another trick. Use thinner copper enamelled wire.

[@Alexwhatisit]

Cool, but what does the mod do?

[@notman2k7]

Plays any region game and allows playing of backups

[@originalzero455]

Hello Voultar i have the same model of psone and i tried to grab the multimeter and test continuous but i missed the pin 3 and 4 you install onechip 8 wire? why i can't have continus on multimeter???i.imgur.com/F5I7Hcp.jpg picture take by: Huawei mate 20 pro

[@PROSTO4Tabal]

What this mod do ?

[@guspaz]

Huh, would have liked to have seen the stripping and soldering of the wires to the adapter, that seemed like the trickiest part. My difficulty with fine pitch soldering seems to come more from eyesight than stability. I bought a magnifying headset, but the damned thing doesn't fit well over my glasses.

[@h1ghju1ce]

Did you try removing your helmet 1st? It seems like that might negatively affect your head stability :P

[@Uzumaki82]

Tried with contact lenses?

[@albertogallegos5966]

Lol, you had to pick the most noisy thing you found. What wrong with some quiet soldering.

[@everettariaz6103]

What does that chip do

[@notman2k7]

Plays any region game and allows play of backups
