Games forced into 480p are using the framebuffer as output with no scaling, so an 8:7 image is sent to the display.
>Gamecube for example didn't have this limitation
Gamecube always pre-scales. It also runs games at the same 8:7 aspect ratio.

Some games are perfectly fine, most renderware games are proper 4:3 480p. Invest in a scaler to address this and you can enjoy all kinds of games in 4:3 480p.
