  Getting 240p on 31KHz CRT Monitor with MME4CRT
Posted by: daifuku74 - 01-03-2020, 11:35 AM - Forum: Support - Replies (3)

Hi everyone,

I installed Mubuntu-MME4CRT-desktop-amd64-v1.iso on my Core2Quad PC
and it seems great.

I'm using it with a CRT 19" Trinitron PC Monitor (VGA)
So I launched the "31K install" from the "start menu" and "games", and then rebooted and launched Retroarch.
Once inside if I try loading a rom it works but does not switch to low resolutions.

Myabe I connect the monitor at the wrong timing?
or I need a tool similar to VMM for Linux to generate resolutions first??

Is there a tutorial or something? 

Thank you very much

  HDMI to VGA supported?
Posted by: suverman - 07-17-2019, 01:36 AM - Forum: Support - Replies (1)

I have an Intel Skull Canyon NUC which is decent powerful, however it has just an HDMI out. I tried to look for examples if this works but didnt find much. Does MME4CRT output 15KHZ through HDMI which can be converted using HDMI to VGA convertor?

  Gameboy native resolution support
Posted by: rainbowroad - 06-29-2019, 12:11 PM - Forum: Support - No Replies

The gameboy has a resolution of 160×144 pixels.

I think I read somewhere that video cards and or crt switchres don't support this low resolution.

Is that correct?
What is the best way to display as close as possible the native resolution of the gameboy using crt switchres?

I'm very sorry guys. I have been overwhelmed with work and study, I have not had time to keep up with the forum or release MME4CRT OS (Mubuntu)

Please bear with me, I have exams next month, Once they are over I will be back  Cool

  Linux Multiple Monitor Setup
Posted by: alphanu - 04-25-2019, 02:22 PM - Forum: Knowledge base - No Replies

There is a built in option within MME4CRT that allows you to choose only one monitor for CRT switching and keep you LCD monitor untouched.

Some times this can be hard to get right.

Simple steps are to choose your monitor index from within retroarch settings. Change this from auto to either 1, 2 or 3 depending which output you want to use. That was the easy bit!

To actually get this you work you need to enable extend display and not have mirrored displays. this can be done via the Linux display settings or using an application like Arandr. With Arandr and some display setting managers these settings aren't saved on reboot. In this case use Arandr, make your changes then save the layout. open the layout file and copy the line into either your .xprofile or Openbox autostart file.

Note that when you extend your display you need to do them in the order that the display output appears. Otherwise this will not work properly. type 

xrandr | grep " connected" |  awk '{print$1}'
in terminal to find the order of you displays. remember that MME4CRT does not count disconnected outputs. So, this command only shows connected outputs. If your CRT is connected to VGA and this comes before the output for your LCD you need to ensure that when you extend your displays, you put the CRT on the left. Otherwise make sure its on the right. 

Once this is done. you are good to go.

Posted by: FreZeeN - 03-21-2019, 06:58 PM - Forum: General discussion - Replies (1)

i have some questions

1) whats the best hw build for mme4crt?

2) whats best visual output? dynamic, fixed or native? 

3) what differences about nvidia ati and intel gpu?

4) what about diffrences 15khz crt and 31khz lcd? 

example: is a ryzen 5 2400g integrated GPU compatible with mme4crt full features?

sorry for all questions

  VGA csync option for ATI video cards
Posted by: alphanu - 03-20-2019, 08:38 PM - Forum: Latest News - Replies (4)

I have been asked by a couple of people about adding csync support for ATI cards. This uses a single VGA output for a true csync value. There will be no been to combine your sync signals anymore.

Would adding this functionality be of a benefit to you?

I'd like to propose a project for an official cable for a MME4CRT setup.
I've been working on quite a few PCB projects in EAGLE in the last decade and would like to contribute to MME4CRT with this.
(If everything works out, maybe the final thing could be sold here, we'll see...)

There are quite a few options to connect your PC to a CRT Television or Monitor, but my personal opinion is that none of them is really able to perform a seamless transformation from a PC to a videogame console... either you need a separate PSU or you end up with bulky scart-to-scart leads (or at least monstrous cable-beasts that carry video signals, sound and power in separate leads). Last but not least I think none of the available options are cost-efficient for the end-user.

In the past I came up with an idea - I integrated a small PCB inside a SCART connector which can hold many different parts depending on whatever the purpose may be.

(The following links to a page in German, sorry, but you can see many pictures of the progress)

[Image: 20150209_231045.jpg]

I will design 2 circuit boards that will feature everything to get the best possible visuals, audio and all the voltages that your TV requires to switch into RGB mode and enable 4x3 non-letterboxed format. The first PCB will go inside a little case and has inputs for USB, VGA and Audio. The second PCB will be situated in the SCART connector to ensure an easy assembly.

Setup could be like this:
PC -> (short cables) -> little box with inputs -> (Scart or BNC cable) -> [TV or Monitor]

Here's my feature list:

  • Open-Source Design: Build your own or buy one, whatever suits your budget without losing any features
  • Properly shielded cables
  • H/V Sync-combiner-circuit for true C-Sync output
  • 0.7 Vpp @75 Ohms within specs of what any TV expects to receive
  • Separate Audio-Ground for noise-free sound
  • StepUp-Converter to provide 12V for switching to 4:3 mode (Scart-Pin#16)
  • Optional proper Stereo/Mono conversion, switchable (nice2have if your TV only has mono)
  • Inputs:
    VGA -> Video
    USB -> 5V Power
    3.5mm Headphone -> Stereo Audio

  • Outputs:
    9-Pin MiniDIN to Scart
    -> R, G, B, C-Sync, Audio-L, Audio-R, Audio-GND, 5V Power, GND
    VGA Connector with switchable SYNC (H/V or C-SYNC)
    -> to be used with a VGA-to-BNC cable (for professional studio monitors like Sony PVM etc.)
    Extra Audio connectors via CINCH
  • 15KHz Lock Mode (disables the output if the signal is out of range)

So, this is it.
I'd like your feedback about the feature list and any other ideas and wishes are welcome.

There's no release schedule or masterplan until I start working on it and report some progress.
