- I just finished overhauling the entire Raspberry Pi section of the website and put together a short video that sums up the basics of what most people would need to know. I tried to approach the video both as a beginner introduction to the RPi gaming scene and a refresher for people who've been out of the loop. Detailed information, including links to hardware and software (config.txt) configurations are all available here: www.retrorgb.com/rpi240p.html
I've been 240p gaming on RPi's since the beginning and the entire scene has changed so much since I started. Now, things like using HDMI to Component adapters that were previously complicated and finnicky solutions are now excellent ways to get analog signal from a Pi. Also, the software used to launch games has been streamlined and there's some really amazing solutions available. With the addition of Raspberry Pi 4 support comes the possibility for using runahead modes, which means there's the potential for extremely low-lag gaming on certain arcade board or console emulation!

This is the most perfect video if you're getting into this. I recently bought a Pi to Scart and it works really good! Thanks for providing such good content!
I was just thinking about this the other day. Watched your old videos too. GJ
Awesome video! Thanks for the RPI 3 solder solution. I have two lying around and this is perfect!
Excellent video, nice refresher
Perfect video! Doing just this with some retro Japanese CRTs in Tokyo.
superb overview of the different solutions, didn't even know that HDMI to CRT was possible. Great job!
Never worked here. Wasted 40 hours across 3 years trying configs.
@@messiahmozgus Sounds like you never did it right to begin with.
Yes, I and countless other people have hit the same brick wall. There remains no proof it can be done anymore. It was likely patched out with later versions and no one cared to fix it since then. Stop trolling. @@lancepage1914
Hey, this video was very helpful. You seem like a cool guy. Thanks for the info and your amazon list of good cables and converters really helped. Going to use my Pi3B+ with my Trinitron in no time, (hopefully!)
Hey, I cannot get this to work. The RGB converter works when I plug the component cables into an HDTV that has those inputs. But when I plug the component cables into the Trinitron, I get a noise signal. I've heard it may be because not all trinitrons support Progressive Scan. Is that correct? Anything I can do to get RGB from a Pi3B+ on my Trinitron? I can get a model number if needed.
I bought the RGB-Pi a few months ago and i"m completely satisfied. I use it for Neo-Geo and arcade games on a consumer grade CRT. Which means anyone doing this will also need a scart to component transcoder. The software is really good, too!
anyone who doesn't own a scart tv
@@googleboughtmee Which is 75% of the audience.
you know its Informative and educative video when you see him
New subscriber. I love my rgb-pi jamma. And am planing on ordering another. I have 5 full sized arcade cabs and wanting to have one set up for horizontal and one for vertical games. All I play is arcade games on what I have but might have to add the consoles that have up to 3 action buttons. Only because I don’t want to add extra holes in my control panels. The word on the rgb pi discord is a new os is coming soon. With a ton of more options.
RGB-PI is the best and more consumer friendly way to do it, at least for the person not very familiarised with mini computers and computing in general (like me). Almost plug and play, and in the best possible quality.
I like how you put that 'RGB is consumer friendly'. Perhaps if you live in Europe where nearly every TV has a SCART input. That's not the case everywhere in the world.
Your videos look extremely good
Thank you!
One advantage of going with the HDMI to DAC solution as opposed to the hats is that you can do both 240p and 480i. Also, while Recalbox has a couple of disadvantages, I've found it to be the best for non-composite analogue output, as it offers great customization of specific video mode for each emulator/core, ES menu, global video, kodi, etc. This is great for SD CRTs to set some things to 480i like the menu or media player, and even better for multisync monitors that support higher scan rates.
good video Bob, one question,
what about the modelines? how do the software distributions deal with this?
each console has its specific 240p timings, with at least one or more resolutions.
do they handle the specific timings per console/ game
or just have one for all?
the rpi2jamma / rpi2scart (French board you mentioned months ago) deals with a specific modelines per console and per game if needed.
I’d really love to see a CRT-lag test comparing real arcade board vs Pi vs Mister Vs GroovyMame so I’d know once and for all what’s best way to emulate arcade boards
That's easy, the data does exist so we don't need to waste time re-testing this.
It goes:
Arcade board = Mister < GroovyMAME < Pi.
Mister is about 2ms faster to GroovyMAME. But comically 2ms means a world of difference to some people. Mister is quite pricey and can be difficult to acquire and doesn't emulate as many games, hence why I use GroovyMAME the most. A PC will always kill Pi no questions asked.
i love your little lag tester, I'm really curious what the lag is like on a raspberry pi 3B+ composite out on a CRT, it seems pretty low
I feel like you answered this in a recent video but any recommendations for switching between a Pi and Mister? Also more specifically something like a KVM Switch to also switch the USB controllers with low latency. My dream setup is a 4pl Cab that switches between Mister for authenticity and Pi for library.
Thanks bro it works tq
I have a RetroTINC component hat and it is pretty neat. I wish I had bought the s-video one though.
Thanks for the HDMI to Component suggestions. Pi4?Config files from your site are still the best ones to use? Would you recommend that method over 3.5 composite?
Will the rgb-pi image work on the mini jack-rca output like a composite signal? Their OS is literally the best :) ✌️
Thanks for the info! P. S. I like the background music on 5:30, could you please share the name of the track?
Awesome video as always but the background music was too loud for my taste.
yup, same here but great content none the less !
Best part
Excellent video! I'm and RGB--Pi fan. I have a review of it on my channel and also give you a mention! ;) I hope to make another video soon reviewing the new v2 beta OS.
kick ass!!!!
What options are available for vga output ? I saw the retro tink one but it is not available ... any others ?
I'm looking for YPbPr cables plus audio (so five RCA in total) to get for my COMP2RGB from my gcompsw. The cables shown at 5:10 look absolutely amazing (so thicc and sturdy/shielded by the look of it) and I need them. Are they custom or are they available with RCA on both ends?
Oh my GOD they have RCA on BOTH ENDS. Bob, talk to me. I'm sweating like crazy over these cables.

@@RetroRGB Either the Amazon link doesn't play ball with my region or that's a link to 6 foot HD Retrovision cables. I need them a lot shorter and the ones at 5:10 seem to be exactly what I'm after.
Typical I typed out a response and video autoplayed next before I posted it! Anyway I was saying I have a custom circuitboard VGA - RGB scart I purchased online that requires a power supply but haven't tested yet, trustworthy seller though. I have 2 great CRT tvs one late 2005 model that has component cutouts on the plastic shell for the tv covered by stickers so I reckon the board itself just needs modded shame I know no one that can do it.
How might someone play emulated games (say via Retroarch or Fightcade) on their PC with a CRT as their display? My GPU outputs DVI if that helps.
Hey, I love this video, but I can't get it to work. I'm using the HDMI to Component lag free adapter from your amazon store page. But the config file seems to be where I'm having trouble. I've tried just about every config file suggestion i could find on your site or on the schmup forums you linked to. No dice. Anyone able to help me get in touch with Bob or help me out with a config file that might work?
I think just connecting my pc to my tv with a long hdmi cord to a component converter is a better idea every day. That or softmodding my 360 and just playing games through that!
All of those are great ways to experience software emulation...as long as you're outputting a resolution your CRT can accept. Remember that most CRT's are 15KHz, so 240p or 480i only. The point of using a RPi is easy 240p output.
I found you searching for a way to use a pi to be the converter for DTV to analog - for an old and small portable TV. Not sure I saw the solution here. Would I need a pi and SDR combination? This would be a solution to use for local DTV channels on the old portable TV. There are so many old portable TVs out there, and obviously they're very cheap...
Thanks for the video. Can Rpi break/kill a PVM/CRT monitor due to digital to analog (hdmi to analog) signal/frequence difference in time? What adapter/cable to use to avoid such issue while emulating retro games via Rpi(4) connected to a Sony PVM?
All these so-called 'issues' are in fact all non-issues.
Raspberry Pi will not break or kill your CRT provided it can actually display a proper picture. If it doesn't display properly, then the modeline you have selected is simply incompatible with the CRT and it will look doubled or warped. Just don't leave your CRT on for long periods of time when this happens and it won't damage your CRT.
With CRT what you see is what you get, you can be rest assured if it doesn't look right then it isn't right at all.
Digital to analog video conversion has no ill effect on your CRT, and if it did - then how else could you possibly achieve Pi to CRT?
As for 'an adapter that avoids issues' - you have dreamt up an issue that's not even there. Because the whole point of this video is that Raspberry Pi is capable of displaying picture on just about any CRT, unless of course you want to buy an adapter that costs as much as a Pi to do what the Pi can do already out of the box?
How can use RPG-Pi os with RCA output?
I change the config file with data on the website and it didn't work.
Hi,so I can dowload a img rasp 4 and play Deathsmiles..cotton 2..naomi..atomiswave...?

Can you put a link in the description for the retro tape ultimate
Hi, whats about that GPIO to SCART cable is there some information how to maybe DIY it? I'm not afraid to cut one because yesterday I got myself a sharp tv with only one scart input on the backside. The guy who sold it to me showed with a cable from a receiver how it really displayed something so all good it works but I have trouble with my Pi and A/V out cable to get a picture at all. Right now I'd use a 3,5mm plug into the pi with RCA cables on the other side. These ones go then in a RCA to SCART adapter since I'm not sure about this whole order thingy where video/gnd/aud is I will today try with direct soldering how you did on the under side. But literally nothing has happened say if at least I would have gotten some glitchy signal I'd know I messed something up but changing the config and cmdline.txt plus what appears to me the right cable didnt work at all. So I'd be interested in maybe make this gpio scart cable too just in case
Can I use a photo from your video in a content on my channel?
Hey there, I'm hoping you can get back to me on something. I went through the wonderfully laid out documentation on the RetroRGB website and I felt as an entry-level into the RPi on CRT I would simply solder an RCA cable onto the board itself for the time being. That being said, I was curious to know if the jack itself would still be function and act as an audio output? Hope to hear from you and thanks for the inspiration to get back into CRT gaming :) -C
Hello! I think you'd just need to edit the .ini file and audio will come out of the 3.5mm jack. I've also soldered an RCA cable for composite and it worked great!
Nice...video..iam also.making..raspberry pi projects....😇🤗
Hello great video and analysis! But I will tell you that I am already going crazy trying to define and decide what would be the most appropriate alternative to connect my RB Pi 4 (4g) with a CRT Sony Trinitron TV with component RGB input (YPbPr). I have to decide exactly which model to buy, recommendations are accepted! I know I have these options: VGA666 (works fine with Pi 4?), RetroTINK Ultimate (but no longer for sale), VGA666RGBS (maybe best for Pi4?) Or HDMI to Component Converter, PORTTA HDMI to YPbPr Adapter HDMI to 5 RCA RGB (NO scaler). This last alternative also works for a PC, right? What do you recommend that is simple and allows me to run arcade games at native resolutions automatically, 240p / 15khz / scanlines? I hope you can help me. Thanks a lot!
I'm currently trying to figure this out too. Were you able to get the pi 4 on a crt?
@@glowingmemories Not yet, but the RGB-PI operating system (the new version they are developing) and the new Recalbox 8 will have RBPi4 and CRT compatibility. The Recalbox 8 there is already a beta to download and the official version will be released in the next few days. Soon you will be able to try Recalbox.
I get a composite signal out of my raspberry pi 3b+ by simply plugging in my xbox 360 cables into the port next to the hdmi port it outputs video and audio
I got the same HDMI to Component box, still having problems with getting it to look 100% right. Do you have a base image?

My issue is "that box" changes all the time. I ordered one that did a great job off aliexpress, and the next time I got the same case, but the board inside was now one that did scaling. When I complained they said its upgrade version. Should have noticed that the price had gone up.
Follow this guide,it works fine on my pi but only difference is I'm using a hdmi to vga but that shouldn't matter.

I’m trying the same thing and isn’t working either. Would be great if someone can provide a working config.
@@diegobouhot ill let you know if i find something Diego
@@facufeg86
I figured it out. You should use:
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87
In config.txt. The line hdmi_ctv creates a custom resolution with some other parameters (it's all in the raspberrypi.org docs), and then you select that custom resolution using the group 2 and mode 87. This is reserved for custom modes, and it's equivalent to DMT 87 HDMI (in recalbox.conf).
And then in recalbox.conf you can use a different resolution for Emulation Station, selecting another mode like CEA 6 HDMI. Like this:
system.es.videomode=CEA 6 HDMI
That line is commented with a semicolon, you should remove that in order to make it work.
One thing that happened to me, is that every time I disconnect the power from the HDMI converter I should force another resolution in the config and fallback to the custom one I've created. Otherwise it goes out of sync or make some weird effects on the image. I don't know if thats something exclusive to my adaptor.
@RetroRGB what is that song? I fucking love it.
Playing raspberry pi on a crt tv gives natural scanlines??
Is the HDMI to Component converter compatible with the RGB-Pi system to output 240p?
This really depends on what your TV can do. Because a HDMI to Component Transcoder is a completely different method to RGB Pi which is a hat for the Pi the outputs to SCART.
If your TV has a component video in, then use HDMI to Component Transcoder.
If your TV has SCART, then use RGB Pi.
If your TV has composite video in only, then use the Pi AV 3.5mm cable for it and use that.
i bought a deamon usb enconder, and in some arcade games keys are not reckognize. anyone have this issue on RGB-pi?
what do you think of crt pi
Thanks! I bought hdmi to svideo coverter on ali and its crap, i was just wondering with what to replace it. Lol awesome timing!
I'm some what confused that pi output composite but does not input. Does anyone know why? Seem like if you got a D/A chip to convert the digital video to composite, the reverse should be possible.
Those DAC / ADC's are rarely bi-directional. The Pi's would essentially have to add video capture software and hardware to support that. It would be cool though!

CastleMania Sells them now: bit.ly/2QTc5IG
@@RetroRGB than you Bob :)
But what's the point of using the HDMI2Component converter if its minimum supported resolution is 480p?
The Avedio you recommend supports "480P@50/60Hz, 576P@50/60Hz, 720P@50/60Hz, 1080P@50/60Hz"
These companies never list 240p as a supported resolution. Sometimes they say 480i (both are 15KHz resolutions). Other times they just say 480p, but they still work with 15KHz.
...and sadly, it's becoming more common to see ones that say they support 480i, but don't go lower than 480p. That's why I link to stores that allow returns.
@@RetroRGB So there's no way of thru-passing 240p via HDMI if I understand correctly.
People on Reddit claim they have done 240p but when they share their config txt files with me it never works. I've tried 2 non scaling HDMI 2 ypbpr boxes.
@@messiahmozgusthat's solely dependent on if the video chip is capable of running at a low enough pixel clock speed to produce 240p 15khz. Because the HDMI standard is capable of passing through a 240p 15khz signal. A wider integer scaled resolution (for example 1280x240) may have to be used to reach the video chip's pixel clock speed minimum to work. Kind of like how super resolution works. CRTs don't discriminate higher resolutions horizontally, only vertically.
@@lancepage1914 it is because the bios boot screens work. Doesn't matter. I sacrificed my shell and just went with the VGA to YPBPR route. Works great.
All these options are great but I'm still surprised that nobody ever talks about the Nintendo Wii as an option. $20 wii+$4 component or s-video cable+sd card.
Keith Courage why im trying to find an alternative is while my output is component on the wii the emulation completely lacks depth and texture. A side by side comparison on original hardware even on a composite output is night and day.
@@seanmacdonald5243 it does? Maybe it depends on the system being emulated but I haven't noticed a difference at all with Genesis or TurboGrafx stuff on the wii. In fact, I'd say the Wii looks and sounds much better than a real Genesis does.
So far I only tested NES but I compared my Wii using HD Retrovision Component cables and ran Retroarch 1.9 @ 240p with all the shader crap turned off, threw on the Composite pallette and then compared it to real hardware and it looked and played amazing on my Sony 20FS100. I used Super Mario Bros. 1 for the test because the dot crawl is horrendous in that game and it was super close to just sharper, cleaned up composite. Lots of variables but depending on what you're playing the Wii is a great option
@@alienJIZ1990 give mednafen a try for nes. I think it looks a little better then RetroArch. Could have been my retro arch setting though.
@@Chris-Courage Mednafen for Wii hasn't been updated since like 2012 unless there's a fork I'm not aware of. Definitely give RetroArch another go - the default settings are nothing short of horrendous, so perhaps Mednafen looks better stock but the underlying engine is surely long dated by now. With RetroArch defaults it's blurry af and you have to turn off all shaders, remove threaded video, put on a better palette, and really just remove anything whatsoever that's catered to an LCD. I even had some success with the Run Ahead Latency at 1 frame to remove the input lag from using a Wiimote. Seemed to remove what tiny little lag the Wiimote's bluetooth introduced.
Has anyone tried this with the Pi 400? I just keep getting a distorted image.
Can those HDMI to YPrPb boxes even deal with sub 480i resolutions?
Yes. I show that in this video...a few times.
@@RetroRGBI'm asking because I remember that there's like a specific one that does and the rest that you can purchase in say Aliexpress or Taobao shit the bed at that - turns out you're right, all of them do. I was afraid to splurge on one (they're quite expensive in South America) only to work halfways, like some VGA to S-Video adapters do. Thanks!

I've been looking into this recently. Using the latest Retropie image for RPi 4B. Like the method in the video 5:45 where you use an HDMI to component converter.
EDIT: Further searching and trying, it seems this method won't work for RPi 4 + Retropie at the moment. I believe that's why you were using the RPi 3 in the video.
I cant make it work either. If you find a solution, pleaseeee let me know
I'm trying to do the same with my RPI4 by editing config.txt, however I keep getting blinking mess on my PVM.
However if Rpi4 is connected to an HDMI display, and then swapped to the hdmi2ypbpr converter during boot sequence I will get something which look like a picture of retropie, but splitted in half
Doesn't work for pi3. I've wasted 40 hours over 3 years. I refuse to believe it can be done. The configs on his site just make scrambled grey images.

It's the same as RGB-Pi except without the short ass scart cable.
Options goes from
VGA->Scart cable
(1.5m long) generates 12V to force TV to switch Scart at 4:3 aspect mode.
VGA->Scart adapter
It outputs stereo sound without need of external jack cable. It has internally a DC-DC inverter to generate 12V to force TV to switch Scart at 4:3 aspect mode
VGA->Composite/S-Video adapter
And its only 10€ for the base model and 15€ with the vga to scart cable. Last time i checked RGB-PI was 32€!
So please Bob put this info on the site.
