i downloaded the Lubuntu image provided here on the forums + used the auto-script to install the resolutions on my VGA-1 adapter (https://mme4crt.alphanudesign.co.uk/foru....php?tid=4)

When i tried to activate the SwitchRes everything was just squished, tho.

Am i missing something?

Thanks.

I was just setting up an ubuntu retroarch machine for a crt monitor. I tried with retroarch mainline first, but the modelines generated by crt switchres were off-center.

I tried mme4linux and the issue, while slightly different, still persists.

For example, the modeline generated for genesis (genesis-plus-gx) is as follows (xrandr output):

Code:
CRT7_320x224_59.92 (0x4db)  6.131MHz -HSync -VSync

  h: width   320 start  330 end  357 total  392 skew    0 clock  15.64KHz

  v: height  224 start  234 end  237 total  261

The modeline I was using previously using under windows for crtemudriver is this:

Modeline "320x224 NTSC (60Hz)" 6.700 320 336 367 426 224 236 239 262 -hsync -vsync

xrandr:

Code:
MANUAL_320x224 (0x4dc)  6.700MHz -HSync -VSync *current

  h: width   320 start  336 end  367 total  426 skew    0 clock  15.73KHz

  v: height  224 start  236 end  239 total  262           clock  60.03Hz

Code:
CRT7_320x224_59.92 (0x4db)  6.131MHz -HSync -VSync

  h: width   320 start  330 end  357 total  392 skew    0 clock  15.64KHz

  v: height  224 start  234 end  237 total  261

The modeline I was using previously using under windows for crtemudriver is this:

Modeline "320x224 NTSC (60Hz)" 6.700 320 336 367 426 224 236 239 262 -hsync -vsync

xrandr:

Code:
MANUAL_320x224 (0x4dc)  6.700MHz -HSync -VSync *current

  h: width   320 start  336 end  367 total  426 skew    0 clock  15.73KHz

  v: height  224 start  236 end  239 total  262           clock  60.03Hz

I got this modeline from http://www.geocities.ws/podernixie/htpc/modes-en.html. These are usually very good, and produce a centered image on a monitor that was calibrated using consoles outputting 240p.

The visual issue is that the image is slightly wider than it should be, and the left is extremely cut off. I took a couple of pictures:

MME4crt modeline

manual modeline

Checking with the underscan option of my bvm, I can see that the image starts right at the left edge of the screen, rather than being centered.

I tested with a couple of fba games, nestopia, and snes9x, and they all present the same issue. I tried playing with the X Centering option without much success (setting it to 4 kinda freaked out the bvm).

I am using ubuntu server with nodm + openbox, compiled mme4crt by hand, gl driver.

Let me know if I can provide any more information.]]> <![CDATA[Master System and Game Gear Problems]]> https://mme4crt.alphanudesign.co.uk/forum/showthread.php?tid=46 Mon, 11 Mar 2019 14:26:27 +0000 https://mme4crt.alphanudesign.co.uk/forum/showthread.php?tid=46
Fantastic work Alphanu, some things that you publish we are using in RGBuntu distro. In few days we are going publish the distro in first final version. RBGuntu are much light (1.4 GB with MME4CRT, EmulationStation, Kodi and Systemback), if you want you can use for your system, and you can purge anything of this distro. Is based in minimal Ubuntu with OpenBox.

In our test we see than MME4CRT not working with Master System and Game Gear. This system show a white line.

Thank so much for your great work. And sorry for my horrible english.]]>

My desktop is on 640x480 @ 60hz
Also i notice that i have what sound like crackled sound in most games and emulators in tetrarch, using FBalpha latest, game libretto latest and also in genesis fx plus

My machine should be able to handle the audio i believe :

windows 7
core i7 with 8GB ram
HD5450 radeon with emu driver
SSD disk

Mame 0.206 with groovymame is also installed on this same machine and works great (it's a version with portaudio using d3d9ex)
