Title: crt_emudriver and Retroarch
Post by: R-Typer on October 24, 2015, 10:32:56 am

How to setup Retroarch to work with 240p resolutions? When I select to run a Genesis rom, screen flickers and instead of 320x240 it goes to 720x576i. The Display Driver set by default is GL. If I select D3D or SL2 then Retroarch crashes. I tried SNES and NES cores and they fail to choose lowres progressive resolutions as well.

Does anyone have experience with Retroarch and crt_emudriver? I can't find any help on Retroarch forums regarding this.

Thanks for any help in advance!!!

Retroarch is a pain in the ass to set up, but works pretty well once you get it going. You will need to add a few things in the config file.  By default, retroarch uses whatever your desktop resolution is, so you need to put this in the config file:

Code: [Select]

video_windowed_fullscreen = "false"
Also add the resolution you want. In your case it would be this:

Code: [Select]

video_fullscreen_x = "320"
video_fullscreen_y = "240"
I would recommend making a config file for each system.

No problem.  :) I've spent several hours configuring retroarch. I'm considering making a guide on using it with 15khz monitors. A lot of it was just trial and error.
