Resolution 4:3 and 16:9

[zipfixer]

Hey there!

I have looked all over for a solution to this problem, and cant say I find anything that helps.

Specs:
Model: Raspberry pi 3 model B
OS: Retropie 4.1

Problem i want a solution for:
I want all emulators or just n64 inside emulationstation be forced in an 16:9 Aspect ratio.

If I connect the Pie to the TV and boot up, the emulators will run in 16:9. When i reboot or take the power cable out and boot up it will run 4:3. BUT if i then unplug it and Connect the pie to a different TV it will run i 16:9.

So the only solution for me is: Check it for 4:3 aspect ratio, If not unplug the power cable, Connect it to another TV and get 16:9...

Is there any easier way for me to allways have 16:9? change some config files or something?

Ty in advance

@zipfixer i don't really understand this rebooting thing, but the way to change aspect ratios for some/all systems is via https://github.com/retropie/retropie-setup/wiki/Configuration-Editor

note: this is only for libretro ("lr-") emulators, which are basically all the defaults for each system. for n64.. depends which n64 emulator you are using.
