Gamecube Widescreen hack with proper video aspect ratio

[lagg]

I remember reading somewhere that it was possible to force widescreen on Gamecube games, but have it render videos in 4:3 so they wouldn't be stretched.  I just can't find where I saw it.

So, I'm hoping I can ask here: Is such a thing possible, and if so, how can I do it?

Thank you!

Some games support it natively, but some need an AR code. Go check out the posts in the development thread to see if the games you want to play have a code yet.

There's something called Swiss for the GC. If I recall correctly, it can work with Dolphin, so it may be an option for games without AR codes.
