@duglim said in recalbox x86/x64:
- I spent 2 hours to figure out how to change resolutions on the x64 version. It's running on a laptop with an external 16001200 Eizo screen attached via VGA. I can't get ES into a higher resolution than the standard 720p and the libretro cores also render with a 720p hight. Is there any way to have everything rendered nativly in 16001200 pixels 4:3 aspect ratio? Using global videomode "DMT 51 VGA" did nothing. And I can't find the config.txt file on the x64 build.
CEA and DMT are Pi only syntax
- I noticed that the libretro cores do not show any overlay (Retro / Scanlines). Are they somehow missing or is it my fault?
Overlay or apply shaders ? That's not the same thing
- While running Windows as OS on the laptop, I can switch off the internal screen and only use the external monitor by pressing Fn+F8 keys (usual laptop hotkeys). With Recalbox as OS, this button combo is not working and I had no luck switching off the internal display by messing around in the linux guts. Any idea? Maybe this belongs to the ACPI system?
That's beyond our scope for now I'm afraid 
- Next I need to try is rom compatibility under MAME2010. Thats one of my major goals to have the 0.139 romset up and running smoothly, before Recalbox would be able to take over the crown from my classical MAME/GameEx cabinet setup.
The last time we tried Mame2010 we had major compatibility issues. But that try was on the Pi, I guess higher end CPU wouldn't run in such troubles. That's something we've been thinking of
Thanks for any help in advance and keep up your fantactic work!
I will also consider ditching the old Core2Duo laptops in favor of XU4s, if Mame2010 would run nicely.
Expect my donation soon.

My 2 cents : mame2010 should run on XU4. But as for me, Mamz2010 is faaaaar in my todo list, despite I'd love to see it on Recalbox 4.1
tip : xrandr can be called from es to do the job.
