Question about Widescreen

[Newerabs]

Hey guys, I'm new here and new to Dolphin.

I've been messing around for a little bit trying to get Widescreen to work on a couple games (Paper Mario on GC and Wind Waker on GC). I've heard that it's best to use an AR code or a Gecko Code. My question is what is the difference?

I know how to load the Gecko code but on Paper Mario there are no Gecko codes so I can't edit the configuration and just created one. But it looks like there is an AR code for that game. Is one better then the other? Should I just use the "Widescreen hack" in the graphic options and force 16:9?

I apologize if these are dumb questions and I did do some googling and youtubing to find out how to use the Gecko codes. I'm just curious about what's the best to use.

Thanks!!

Forcing 16:9 will do one of two things:
1) if the game supports widescreen, it will use widescreen mode
2) if it doesn't, it will stretch a 4:3 image to 16:9, resulting in stretched pictures

If you're getting stretching, you'll want to use an AR/Gecko code, as it gives the game a native 16:9 option by changing the way the game displays stuff.

So if I am using a Gecko code for 16:9 do I ALSO have to choose 16:9 in the aspect ratio?

No, set it to Auto at that point

you sometimes have to force 16:9 for some of my codes because of the herustic fucking up on orthographic projection
