- Boy was this a fun project! I honestly had no idea what I was doing, but I feel like I learned a lot just through trial and error. Looking forward to doing more of these!
Here is the pinout I used: www.rigacci.or....

I use one of those adapters as the audio input for my DVI OSSC. Mine is the old version where there originally was no audio but I added Borti’s upgrade board and switched to the A version of the firmware around 2017. Borti’s board is wired to the SCART audio pins. When Inuse HD Retrovision cables I plug them into AV2 and plug the audio into that adapter. They all line up perfectly.
The Genesis DIN8 is 262° (U-shaped) while the one added to your PC Engine is Neo Geo style, 270° DIN8 (C-shaped). You can force the cable in but it doesn’t really fit right.
Also, the Genesis DIN8 is mono with a pinout borrowed from the Master System and Mark III. Stereo is only available through the headphones. Green is on the pin the PCE uses for the second audio channel, which is what caused your problem.
@@emmettturner9452 I was just learning about this recently actually. I have a Mark III with the FM sound unit, but the FM unit has no RGB support. So I built a little splitter so I could get RGB and FM at the same time. Took me a while to find a place where I could order th DIN8 for the Sega systems, but I found one eventually!
@@BofnerAwesome! Console5 has been my go-to for most of this stuff. :)
is it actually displaying RGB or just composite > you would normally need the blanking signal (pin 16 if memory serves) 1v-3v active to switch to RGB mode / < 1volt for composite (although some tv's will switch without ) .. all of them earths connect to each other inside the TV obviously better to use individual earths if they are available..
Hmmmm could be, which would explain why the video for the Genesis was being funky. However, the composite video out was removed on the RGB mod for my PC Engine. I'm not the one who did the mod, but the guy who did told me that it was no longer capable of outputting composite, and I've tested this to make sure, so I can confidently say that at least for the PC Engine, the video going out is RGB. But it's possible that I may have made a modded PC Engine exclusive RGB adapter
Its displaying RGB - PVM / BVM do not have a scart socket like a commercial European TV's but accept BNC connections and you switch between RGB / composite manually via buttons on the front of the monitor.
Can't read the other comments. Some sort of global plot to isolate me. Good video anyway S C A R T
Agora dá pra traduzir 😁
I have a question, I have the same PVM model, that's the 1343MD, right? I would like to know if by making this type of adaptation to the scart cable that you get at a relatively cheap price, you can also connect the PSX via RCA, since that PVM does not have the support for SCART
My apologies for the long comment that follows haha. tldr: yes, it should work!
It's actually a PVM 1344q, but from what I understand they should be about the same. You can learn a lot about your machine by reading the manual (www.manualslib.com/manual/1339662/Sony-Pvm-1341.html#product-PVM-1343MD), but as far as I know, this should work for the PSX. It all depends on how the pin-outs work, but since all consoles plug into the television, the pin-out on the SCART should be the same for all of them.
If I had more SCART cables, I'd test this out myself, but I've only got the one for the PC Engine (My setup is almost exclusively component YPbPr). That SCART cable in particular did not work for my Sega Genesis, but my guess is that it's a problem with the DIN side of the cable, and NOT the SCART side. I think the pin-out for the DIN is slightly different for the Genesis and the PC Engine, so that's probably why the colors didn't show up properly on the Genesis.
While this can be a cheaper solution to buying a SCART to BNC adapter, (www.retrogamingcables.co.uk/sony-pvm-scart-converter-bnc) it will take a little while. soldering all of those small pins on the SCART cable takes a while, and you've gotta triple check to make sure you're using the correct pin BEFORE you solder. It's like they say, "Measure twice, cut once." But on the other hand, this is great experience and a relatively easy electrical engineering project, that I personally had a lot of fun doing. If you've got any other questions regarding this, feel free to ask.
I'd also recommend getting some red, green and blue RCA cables, it'll just look that much nicer haha
Check out Retro RGB on RUclips! He’s a pvm/crt wizard
Hi, nice vid, what was the switch wired to in order to toggle video modes? Thanks
I'm sorry, I actually have no idea! I did this project 4 years ago and have sinced moved 3 times, so the remnants of that adapter are long gone
@@Bofner Thx, no worries. I found that by holding at least 1v on pin 16 (optimum 2.5v) will enable RGB (disable composite)". So i will cut up an old shielded VGA cable or something and build one from scratch. and add composite and Svideo as well. it will keep me amused for a while lol
did you live in spain? do you speak Spanish?
I have a TV with MOD RGB and RCA connection (red green blue yellow/sync). I suppose this same mod will serve me to connect the RGB SCART cables to said TV...right?
Hey! It sounds to me like yes, that mod should work for your television based off of what you told me.
I actually don't live in Spain anymore. I'm currently living in Japan now, but I did live in Madrid a couple of months before I uploaded this video. Y sí, hablo español!
@@Bofner Genial,te escribiré en español entonces.
La TV la tengo hace poco,me he pedido un cable RGB con conexión RCA de AliExpress esos que son para los monitores PVM (sin los conectores BCN por qué no me sirven) espero que funcionen y si no funciona,pues haré este mod para poner utilizar esa TV por RGB ya que acá en América no vienen con conexión SCART RGB.
Gracias !! Japón!!! Genial !!!
@@est-eban4356 Bueno, creo que debe funcionar. Y si no funciona, puedes preguntarme por ayuda. La modificación no es super dificil, pero cuesta un poco tiempo para hacer. Pero con paciencia no es tanto dificil.
I'm here to preserve a spongebob jakks TV game but it only accepts composite video. Are there ever real alternatives to remove composite video flaws to obtain a rgb signal without replacing composite. What's the deal why we can't spilt composite video information on just one cable?
You can definitely mod a consumer CRT to output RGB, but I am NOT the person to ask about this. It can be incredibly dangerous, as a CRT can hold enough current to kill a person. Check out this video by the 8-bit guy if you want to know more: ruclips.net/video/DLz6pgvsZ_I/видео.html
@@Bofner and let me guess here this video is just using downgraded cables for a high quality cable to fit in than the opposite to remove annoying flaws with composite? Just why can't we convert composite signals to upgrade a different signal like RGB?
@@thegamemodder2000 I don't know. I didn't study electrical engineering. My guess is because the composite signal is already being sent through as a single electrical pulse, and separating that pulse into RGBS probably isn't feasible. I would guess you'd have to snag those signals before they get crunched into a single signal, but this is getting far out of my knowledge of analogue video signals
Im stopid🤡Why? Bc my convertor RCA to SCART was broken
Hi i live in spain and have a completo of those Bluetooth adaptora laying about. I was wondering if i can make a scart to component without the yellow just rgb and both audio? As i dont find any cables for it.
It depends on what you're trying to plug it into. It sounds like you might have a TV that takes in Component YPbPr video. That's a different type of video signal, and this design won't work for those
@@Bofner yes after looking over the net i found out that even though they are exactly the same cables and colours they are not the same one is rgbs and the other is ybpr. I was trying to hook up a 10 in 3 scart from aliexpress it has scart rgb out and rgbs component out into my capture card el gato hd which has hdmi and component ybpr
@@eltiburon466 Getting that perfect CRT and capture ard setup is tricky. I ended up going with an extron 12 in 8 out video splitter. I got lucky and found one for cheap locally, but they can run for quite a lot these days, and that's in the USA. I don't know what the situation is like in Europe anymore
Do that scart to RCA adapter provides better image quality? Than just use the normal genesis rca cable? (im talking about image quality on a consumer tv)
Definitely don't do this is you're using a consumer CRT, as they don't have the proper inputs for this. If you want the best video quality, you'll want to get the HD Retrovision Component cables for the Genesis, but ONLY if your TV can accept YPbPr component cables. The best quality you can get out of your console will depend entirely on what your TV can handle
Hello can you make video how to make scart rca for Nintendo n64 thank you
Well I don't have an N64, but the process would be the exact same. SCART is a standardized format, so my little converter will work for any RGB SCART signal, since all it is doing is taking the R, G, B and Sync signals, and outputting them through a differently shaped (RCA) set of cables
Would this work with a regular consumer grade tv that has component input? I am wanting to change my gaming setup and have my eyes on a nice CRT TV. Can't find any PVMs near me for a decent price either.
Good question! Unfortunately no, it would not work.
The reason why it won't work is because RGB is a different signal type from YPbPr (or the component cables on a consumer CRT).
RGB sends out Red, Green, and Blue color data, as well as a synch signal to keep the picture from getting out of synch with itself.
YPbPr sends out a Luma signal (which is labeled as Y and looks like a black and white image), a signal containing the data of Red MINUS the synch signal, and a signal containing Blue MINUS the synch signal.
So the picture won't show correctly if you use the wrong cables. For instance, if you plug the green component cable (Luma) into a G input of an RGB PVM, you'll get a perfectly clear black and white signal, but the TV will interpret that signal as Green and black signal pretty much.
Definitely more info than you needed, but this stuff excites me! Haha
Dude....why didn't you just cut a scart cable. That would have been much neater.
.....this is why I'm not an engineer... But there are actually a couple of other reasons. One is that I only have the one scart cable, and I still need it to hook into my OSSC for capture, and the other would be I have a feeling I would most certainly lose track of which wires went to which pins, and with 21 or so pins, testing out connections to see which pin does what doesn't sound like a way I want to spend an afternoon, especially since I don't own an oscilloscope. But if there IS an easier way to keep track of pins, then I'll probably use your idea and make a new cable
You just don't care. I get it. 😢
About what?
Con que vivías en España... huh
heh sí, vivía en España hasta la pandemia
@@Bofner ostras, entonces por mucho tiempo imagino. Pues nada, saludos desde españita.
composite sync
uses the whole composite signal to find sync
@@Weneedaplague Thanks! I always get confused between the two
@@Bofner The thing that makes it confusing is the word "composite" is used with 2 different definitions. In composite video, it's the combination of chroma (color) and luma (brightness). The sync signal in sync on composite video is buried in that luma signal and the rest is seen as noise. In composite sync, the composite means the combination of vertical and horizontal sync (this is what makes RGB scart different from VGA where that part is seperatated).
@@jordan177606 Ahhh okay. So that would mean I was using Sync on composite, because I was using the composite video pin for my sync, correct?
@@Bofner exactly
