@crinale0 Hi, this looks great! I have an old 20" Panasonic CRT from around 2000 I was thinking of using. What did you use to convert the Pi to a good CRT signal? Are you running RGB, Coax, Composite or RCA?

I haven't tried any of this, but I'm thinking this will be a great winter project.

Thanks!

@henk Seeing as you CRT has Scart inputs it would be a downgrade to pair it with a Composite cable when the CRT has support for RGB. Look into PI2SCART or Recalbox RGB Dual instead and save yourself the hassle and trouble.

@Alessio2001, I ran into this same problem on my last Arcade conversion. The issue ended up being on the CRT side. You should have a control board with 6-8 knobs. Mine was a small square one, but they can be different. This controls the image on the CRT. You can use this to change the Vertical Hold (height), Horizontal Hold (width), and contrast, and some have R/G/B knobs. One of those, when you change it in one direction, made my image duplicate, flicker, and rotate on the screen. When I turned it in the opposite direction, it solidified into a single image rotating from top to bottom. Eventually, it would slow down and stop in the middle of the screen.

By default, you don't need any configuration - a RPI3 will enable the analog video/audio when no HDMI is detected.

enable_tvout is just for Pi4, which doesn't do the switch automatically.

When you're measuring the output, is the cable plugged in the Pi ? If the signal goes through, then maybe the issue is the TV - does it accept composite from other sources ? Do you have a PAL or NTSC TV ?

@AXEL it is such a nice way to play the games as i recall back than, the feel of playing sonic or jurassic park on genesis but nes and snes psx, n64 just can go on, its just home sweet home, thanks for choosing retropie, buzz and the team do such amazing work, i been using retropie for a long time and i wouldnt go any where else glad you enjoy it and it does feel like the gaming on the original thing 😀🤘

@brentriddell to apply it first put the file tweakvec.py into directory home/pi/tweakvec/ on your sd card ( or other storage whre retopie is installed if that).
Then you can enter in terminal window on your PC or in retropie console next:

sudo python3 /home/pi/tweakvec/tweakvec.py --preset PAL60 you get true colors and pal 60 mode (must be sdtv mode = 1 in config.txt to get 60 Hz in all emulators)

But after next reboot you got standard ntsc mode ( with wrong colores), so if you want tweakwec fix always turned on you need write this command in file /opt/retropie/configs/all/autostart.sh It will be run tweakwec automatilly at every retropie start.

But in the end i've get right colors but also get "flickering" in some games. So to get flickering off i've used progressive mode ( write sdtv mode = 16 in config.txt)

Maybe it was helpfully too ( find my messages in the bottom of thread) https://github.com/raspberrypi/firmware/issues/811

@mitu that make sense .. thanks for the help.

Anyone have any experience with this board? It's interesting to see a VGA hat that supports 24 bit colour, was hoping to find someone that has done some kind of comparison between this and other solutions (VGA666, HDMI->VGA converters, RT Ultimate, etc).

A simple workaround is to delay the tvservice call in runcommand-onstart.sh , e.g.:

#!/bin/bash echo "starting emulator "$2 >&2 if [ "$2" == 'lr-fceumm' ]; then sleep 5 && tvservice --sdtvon="NTSC 4:3 P" & fi

@morell From other listings on the site, I found the following:

WBE (wide body extended): Assembled size: 627 x 481 x 635mm (Width x Depth x Height) U-WBE (ultra wbe): Assembled size: 687 x 481 x 635mm (Width x Depth x Height)

But you could always email the guy to verify what the actual numbers are. (use the 'contact' option in the top left)

You could also (probably) even ask if he would be able to supply the artwork in dimensions of your choosing. He is pretty flexible when it comes to custom stuff, so just send him a message to inquire first. It's always worth a shot, right?

@jamesfarnhamlong said in Retrotink U - Higher res ES and PSX games:

The 450x270 looks best, but I was wondering if it was possible to run one @ 720x578 to improve the picture a little. I know the TV supports this as I have an old Apple TV that uses this revolution. How do I write the hdmi_timing to make this work? Is there a calculator or something I could use?

Try this - http://eightvirtues.com/lakka/hat/RPi HDMI Timings Calculator and Core Docs.ods (courtesy of https://www.youtube.com/channel/UCtF_2HGXXPlUi1J0Euw1Qrw).

Is it possible to adapt this to run at 2x resolution so I can use the enhanced graphics in psi-rearmed. Is there a way to have this only affect psx game launching? Or would it then throw out all the other systems? Is there much point?

Maybe if you use the calculator linked above you can derive the correct HDMI timings to use. As for the effect on the other systems, you'll have to ask the author of those configs.

The config is the same, it does not matter if its pvm, monitor or consumer. You will possibly still need some tweaks , depending on your TV (to center the picture). That guide is quite old and so may be the timings he listed. I recommend looking at RGB-Pi or Retrotink configs on github, they're more up to date and work with Gert as well.

@Deityfierezy you are better for now with the 3+

@PUME04 lol no problem, you may want to google "Retropie CRT edition" I've been using that with a pi 3 and a vga666 into a vga to component transcoder .. yes you will spend a bit more money but it works so well ,, but you can not do 480i ,, but its set up to handle all the wacky arcade resolutions per game all done from a config file.

this is the transcoder .. well hes out of stock but keep an eye on him.. about 50bucks

and I use this type of vga666 works really well ..
