Hi,
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):
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:
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.
