Good morning! I wanted to talk about something regarding the Wii’s output that I wondered about, especially regarding whether or not there’s a way around it. GameCube games launch in 4:3, which means if you’re using the Wii in 16:9, they’ll appear stretched on the TV screen unless you change the aspect ratio on the TV manually. I know that this is due to the Wii’s anamorphic widescreen which works by having the TV stretch the image out. Ive seen some interesting cases where the Wii will actually squish the image down so that the TV will stretch it back out to 4:3, some examples being Mario Party 8 or retro game collections. I also know that there’s a Melee mod that has a display mode called “crop” which makes the game appear in 4:3 even when the display stretches the image out to widescreen.

So, what I wanted to ask is, would there be a way to retool these so that GameCube games on Nintendont will appear in 4:3 even on a stretched display? I know that this will compromise the image quality to an extent but I would be willing to do that if it means not having to manually change my TV‘s aspect ratio all the time. I’m assuming it’s through a gecko code that melee can do it, right? What would be the best way for me to approach making codes for games that allow them to do that?

Did you find an answer to this? I'd like to do the same for specific wii/GC games like Metal Slug Anthology ...etc that don't benefit from stretch/widescreen codes. Is there a 4:3 code to prevent stretching? Changing the Wii console aspect to 4:3 is not a desired solution and seems to be the only response I can find.
 
So the simplest answer is that the Wii doesn't know what the output device's resolution is. It just sends (at best) a 640x480 progressive video output.

With 'force widescreen', modern Wii homebrew will render a 16:9 aspect ratio picture with those 640x480 - including sometimes overdrawing content previously beyond the visible borders, sometimes stretching existing picture. The output device, presumably configured to expect 16:9 content, will stretch the 640 it receives across 854.

Asking for a force 4:3 is actually asking for a lower resolution rerender - squish that 640 wide pixels the game designers intended into something smaller and pillarbox it, so that when the output device renders (stretches) it as 16:9 anamorphic, the picture appears 4:3. Some other amount of pixels isn't what any Gamecube game was designed to render at.

It's probably not impossible, but it's also not a common use case. In the case of Metal Slug Anthology, it wouldn't be a pixel perfect rendering - it would be something like 479 instead of 640.

If you just want a Wii to display Metal Slug Anthology, change the Wii settings to 4:3, turn off force widescreen in homebrew, and configure your output device to expect 4:3 content (pillarbox). That would be at the full intended resolution.
