Batocera on CRT

ZFEbHVUE

Hello all.

I hope that in these times everyone is well and your family and friends as well...

I bought an "Arcades electronic" arcade kiosk with a 28" rotating CRT screen less than a year ago. I have a pc inside with groovymame (linux).

After some electronic setbacks (replacement of TV turntable and others), I managed to put a recalbox (rpi3) in CRT (it worked more or less because I had recognition problems with my panel under emulators but not under emulationstation) . But it didn't work at all under batocera in rpi3.

But now I'd like to put instead of groovymame on the pc the
batocera 5.25 (pc64bit) but I don't know how to run it on a CRT.

I guess this question has been asked before but I would like to know if it is possible and especially how to do it. Is it possible to have even the emulation working on CRT like the Recalbox did on rpi3.

Thanks in advance and have a good weekend.

Take care of yourself and take care of the people around you.

Stéphane.

Hi Stéphane.
I'm doing same things , but I'm gonna use a Naomi SEGA Sanwa Monitor VGA 31khz rather than CRT 15Khz.
Here a link about setting up Video output to preferred resolution :
https://wiki.batocera.org/doku.php?id=display_issues
I'was trying to do it , but for the moment i couldn't continue on this.
So , I hope that it could help you.
Take care to yourself bro.

Have nice day😉

Thx guy for the response !

Have fun :D

It is probable too high resolution for your monitor. I have a Sega Naomi and I had the same problem so I changed resolution to 640x480 @60 Hz that it the max Naomi monitor can support and I fixed the problem. Pls follow Batocera wiki (as wrotten by Gnomx)

ZFEbHVUE

Hello all,

KingOfGames and Gnomx

Please, what I wrong on my try on CRT ? I am open to all suggestions.

because on CRT is 15khz the good resolution is for me :

"640x480@50" 12.625000 648 672 736 808 480 534 539 625 -HSync -VSync interlace

Thank to you and take care

Hello, I have seen your post about setting the resolution of batocera and I have the same configuration as you : I have a naomi cabinet and trying to plug my pc with batocera on it but I wasn’t able to set the resolution properly…

Can you help me please?

Gnomx

ZFEbHVUE How is going dude?
Did you do it?

ZFEbHVUE

Gnomx

Yes it worked in some way:)

I have an arcade terminal with a CRT monitor (15khz) with a pc which is able to deliver 15khz with the right card:
Groovyarcade
(PCx64bits)
ATI Radeon X600 256MB.
intel(R) Core(TM)2 duo cpu E4700 @2.6GHz
Memory 4GB.

I wanted to run Batocera on this pc.

On arcade machine (PCx64) with groovymame :
Monitor Type: I chose PAL TV - 50Hz/625 15.625khz

Video card output kHz: DVI-I-1 PCI:01:00:0 (CGA 15.75khz, NTSC TV, PAL TV, VGA 31.5khz I don't know)
DVI-I-2 PCI:01:00:0 same here

Video Boot-Grub : I chose [PAL DVI-1 15khz]

I've already done what you advised me to do on a different pc with Batocera.
Batocera
(PCx64bits)
AMD Radeon HD6450
intel I7-2600 (3.4Ghz)
8 GB.

I change the resolution to 640x480 59.94 like you said (wiki.batocera.org) with an ssh connection. Xrandr not being able to be launched in ssh, I took the hand with F1 then with an xterm in the applications. I made the commands to restart Emulations with the new resolution.
My LCD screen accepted the new resolution.

But it was not my goal. I tried to do as show in the video:

I added the line:
xrandr --addmore DVI-0 (because before it was on displayport)
xrandr --newmode "640x480-15khz" 13.218975 640 672 736 840 480 484 490 525 -HSync -VSync interlace
But under Groovy Arcade the Pal mode is more like following and works better than the previous one (I tested it on my arcade machine):
xrandr --newmode "640x480-15khz" 12.625000 648 672 736 808 480 534 539 625 -HSync -VSync interlace
xrandr --addmode DVI-0 "640x480-15khz"

In the video the person did : xrandr --output DVI-0 --mode "640x480-15khz" but it didn't work
so I rather edited ~/.xinitrc by adding : xrandr -s 640x480-15khz
/etc/init.d/S31emulationstation stop
( /etc/init.d/S31emulationstation start) i don't do that because i knew my LCD ddoesn't accept the new resolution.

So I made a shutdown and then I plugged my HD on the arcade's pc but it couldn't boot on it and switched back to Groovy Arcade.
So I plugged the PC I used to boot the batocera on the arcade terminal and I got anything on the screen ... just skewed lines so an image that has the wrong frequency or something .......
Anyway I boot with the pc where there is groovyArcade or with the pc where there is the batocera boot for CRT it doesn't work yet ....
Thanks again for your help and take care of yourself.

Just to be clear:
Are you using an arcade monitor or a tv ?
How is connected your pc to the monitor ?

ZFEbHVUE

KingOfGames

Hello :)

To be clear, an arcade monitor and an old TV are the same thing. Both work at 15KHz. These are CRT tubes.

My arcade terminal is Arcades Electronic 28" rotating screen. Due to an electronic problem with the electronic board of the monitor, I changed everything with an old 28" classic TV and it worked until recently. For testing purposes I plugged another smaller CRT TV with a SCART socket (jamma jack tweak)

640x480@50" 12.625000 648 672 736 808 480 534 539 625 -HSync -VSync interlace is good :-)
It's work on my arcade terminal

What I wanted to tell you is that tonight with a pc (AMD Radeon HD6450) connected to a pc with Batocera and two screens (LCD and the one on the terminal through the jamma well it worked for ES in 15KHz but as soon as you run a game you get a black screen and back to ES.

I wrote it on an LCD (DVI-1 or displayport) after F1.
xrandr --newmode "640x480-15khz" 12.625000 648 672 736 808 480 534 539 625 -HSync -VSync interlace
xrandr --addmode DVI-0 "640x480-15khz"
xrandr --output DVI-0 --mode "640x480-15khz"

But when I wanted to put batocera on my arcade PC (ATI Radeon X600 256MB) with both screens (booting on LCD), and I do the same with xrandr, it didn't work and I got a lot of lines on the screen.

I want to put some pictures but I can't

Bye

Because when I set 640x480@60 hz on my SEGA Naomi monitor I was sure it can support such resolution and frequency (it is a 31khz monitor).
In your case if it is a 15Khz arcade monitor I think 640x480@ is wrong and you should try somthing like 321 x 240 @ 60Hz or 256x240@60

KingOfGames

To be clear, an arcade monitor and an old TV are the same thing. Both work at 15KHz. These are CRT tubes.
It is not 100% correct they are similar but different electronics

ZFEbHVUE

KingOfGames

A tube is a tube, the electronics behind it are the same thing to be able to supply it and the deflection of the electrons. You have same ballast transistor and THT and other components and depends of the size of your Tube because it's not the same voltages ont it.

Mine is French made (ahahah) was called Monitronic (go to see on net and the lots of problems with it) I have never seen something so damn !! I replaced the monitor and the electronics for a 28 "TV. No comparison possible, the TV is much better than this Monitronic shit.

One of the only electronics valid for a monitor that people take for their arcade machine is Hantarex !!

The thing that differs is that on a TV there is also the tuner part and the socket is in scart while the electronics of an arcade terminal has a jamma connection which delivers RGB to electronic of monitor. But the scart is also in RGB then ...

For information I am French :-)

KingOfGames

Try to do the same I did (following Batocera wiki and not the video you posted) :

STEP 1 : Connect your PC to the LCD only
STEP 2 : Start Batocera and press F1 and then Xterminal
STEP 3 :

cp /etc/X11/xinit/xinitrc ~/.xinitrc

export DISPLAY=:0.0

xrandr

vi ~/.xinitrc

You'll see a section with:

#####################

CUSTOMISATIONS

to customize your display, you can copy this file to ~/.xinitrc and then modify it

rotate the screen

xrandr -o left

xrandr -o right

xrandr -o inverted

change the resolution

xrandr -s 640x480

change the resolution and the Hz

xrandr -s 640x480 -r 60

#####################
#####################

Just uncomment the corresponding line. In your case force to 64o×480@50 (just remove the first # character

Let's save and quit ([Esc]:wq for vi).
STEP 4 : ESC from Xterminal and Esc from F1 mode and restart Batocera

STEP 5 : If the resolution it is changed, shut down and connect PC to arcade monitor (only)
STEP 6 : switch on....and let Batocera loading. If you do not see anything...the problem is resolution and you need to change to lower resolution and/or Hertz

Thank to you
xrandr -s 640x480
yes I did it previously but with no issues
This work on my LCD and i have 640*480 . it is more and less unreadable when you do f1.

I go to try what you say and i will say what's happened in 15KHz

Thx

Stéphane.

Hello all,

KingOfGames

Ok it's working now but in my way with a mix with the video i show you.

Like Gnomx said for wiki batocera before (i did it but not in the good way)

I put new modeline (directly in shell) with xrand before and modified .xinitrc : put away the # of xrandr -s 640x480 or of xrandr -s 640x480 -r 60 or xrandr -s 640x480 -r 50 : It's not the way to do what i wanted.

so I did again :

cp /etc/X11/xinit/xinitrc ~/.xinitrc
export DISPLAY=:0.0
xrandr

You must put these following lines into .xinitrc with the commands presents into the video: ( # are only comments ) :

#change the resolution
#xrandr -s 640x480
#change the resolution and the Hz
#xrandr -s 640x480 -r 60

#adding new modeline for Pal monitor
xrandr --newmode "640x480-15khz" 12.625000 648 672 736 808 480 534 539 625 -HSync -VSync interlace

#adding the new mode into the DVI-0 section
xrandr --addmode DVI-0 "640x480-15khz"

#put this new resolution and new frequence into output DVI-0.
xrandr --output DVI-0 --mode "640x480-15khz"

Ok I have got a problem to booting with my usb key (Batocera 5.25) on my arcade station but it worked one time on
my CRT TV screen !! i don't know why (USB 3 perhaps).

I did the same procedure with my old HD (Batocera 5.22) on it works (always) perfectly with my arcade station in 15KHz :-)

Here I tried very quickly with one game by emulators. Almost games work fine !!!

Hi guys long time.
So , I noticed that you have achieved your goals , congratulations!! 😎😎
Just a question , what graphing card are you using?
🤔

ZFEbHVUE

Gnomx

Hi Gnomx :-)

I put already specification of my PC arcade on this post :

ATI Radeon X600 256MB.

No congratulations, because I’m a little disappointed with Batocera.

I actually managed to display on a CRT (at 15KHz 50 or 60Hz). But not all emulators work with it and it depends on the version I used (for test 5.22) and I tried 5.25 …

For example N64, dreamcast or WII work in slow motion (with lague in music and music) or not at all according of I don’t know probably the resolution and frequency for CRT … 🤔

As soon as I set up my arcade terminal panel (long desert crossing because because I hadn’t any anwers and I found by myself …), I got problems with lineapple, it reconized my 8Bits pro SF30 but not my panel with two joystick. All other games can be used with my panel. I tried to modify linapple.conf but for screen it’s ok not with joystick.

Amiga (FS-UAE) nothing works (not even a simple adf and even less the WhDload …). Only the libretro-PUAE version works.

Thx for your anwers few time ago

Finally I got my Batocera working on my Naomi cabinet.
Take a look at this pic guys , this isn’t 15khz but 31khz 640×480 60hz

But I need to modify or remove spash screen , because if I don’t , this is the result :

It happens because booting screen resolution is higher than 680×480 and this kind of monitor can’t handle it.

Can someone help me on this ??
I need to modify Booting resolution or hide it.
It can damage my monitor if I don’t. 🤯🤯🤯

ZFEbHVUE

Gnomx

Which Batocera version have you ? I don’t have this Joystick Batocera screen anymore.

Each time I start batocera 5.25 or 5.22 on my pc with a CRT monitor 15KHz, I see the screen of bios and and after the Batocera linux booting split in two vertical parts and after when ES start with Joystick Batocera picture the screen is correct in 640×480 (50Hz or 60Hz) interlace.

Stéphane.

KingOfGames

Gnomx It happens the same to me and I would like to understand how to fix it🤯

Gnomx

Hello! I’m trying to do the same with my naomi but no success…. What configuration did you set for the resolution? 😊

Gnomx

ZFEbHVUE after when ES start with Joystick Batocera picture the screen is correct in 640×480 (50Hz or 60Hz) interlace.

How can you did it??
