Mame_libretro - "invalid video value opengl; reverting to software"?

Hi all

When ever I run a game through RetroArch using the mame_libretro core, I get that message displayed. The game still runs, but it seems to hint that it no longer uses my graphics card, but reverted to software rendering. Here is the full output:

D:\Emulators\RetroArch>retroarch.exe “D:\ROMS\MAME\varth.zip” -f -c “D:\Emulators\RetroArch\retroarch.cfg” -L “D:\Emulators\RetroArch\cores\mame_libretro.dll”

D:\Emulators\RetroArch>Error opening translation file English Adding monitor screen0 (640 x 480) a:1.333333 Invalid video value opengl; reverting to software exit scope, restart empty driver Adding monitor screen0 (224 x 384) a:0.583333 Invalid video value opengl; reverting to software

I just tried updating to latest core in RA as of 1/20/2020… and it still generates that message.

That’s normal, AFAIK. RetroArch always uses software rendering for MAME.
