Resetting RetroArch config did nothing

Try in RA Settings >> Configuration >> Save on Exit.

Where are you changing brightness? I couldn't find the option in the main menu.

In /storage/.config/retroarch/retroarch.cfg you can manually change the number under:

screen_brightness = "100"

It seems it might reset in the code, as AmberELEC has a patch to disable the reset here:
https://github.com/AmberELEC/AmberELEC/blob/dev/packages/games/tools/retroarch/patches/retroarch-disable_brightness_setting.patch

In ES: Start > System Settings > Brightness

/storage/.config/retroarch/retroarch.cfg

already I have screen_brightness = "10"

Sadly none of your suggestions are the solution.

What is strange is that I remember this being a problem when I first got my device, then it was solved, and now it is a problem again. IIRC

@shantigilbert
Will probably have to look into this one, because we usually have a patch that should disable the resetting of screen brightness located here:
packages/sx05re/libretro/retroarch/patches/OdroidGoAdvance/9999-emuelec-unify-brightness.patch

Gameforce should also use these patches. Maybe they are not applying properly.

[Langerz82]

I used an similar Odroid-Go Advance device and the brightness settings were being applied. Shanti might have to take a look at why Gameforce is not working the same.

The patch still works fine for oga/ogs and gf, it just isn‘t applied to the 32bit version of retroarch. This needs to be fixed.

[gingerbeardman]

Aha! That would do it.

I am using 32-bit is that it's the only version that I could get to run Beetle Adventure Racing and look OK
