The Wii and GameCube, however, do a huge amount of their graphics work in integer format, so it's likely that the final render result will be a number corresponding to exactly to the integer the screen wants, making it hard/impossible to change the conversion after the fact.
So it would come down to hacking a few select games? Question is, would it be legal enough to ship with dolphin.
