No, and it's not possible.

gego51 commented 1 year ago

Ok. Thanks for your answer.

You can't add blacks marges in "3d+2d" on the option "force widescreen" called "marged"?

I know the gamecube can't render 16/9 screen, but stretching horizontal scale of game's render to 0.75 and hading black marges could not impossible.

Extrems commented 1 year ago

It is impossible because the hardware does not support ratios smaller than one.

gego51 commented 1 year ago

I don't thinks to reduce the render of hardware, but add an overlay (for marges) to the game with "widescreen force" mode to get a simili 4/3 merged showing on widescreen TV.

Extrems commented 1 year ago

That's even less possible.

Ok. Thanks you for your's answers.

Why would one like to force widescreen, then crop to 4/3?

There are zoom options on TVs called "pan & scan", or even more obviously "4/3", combined with overscan to crop around a little, may give you the result you expect. Some smarter TVs might even have zooming option with 4/3 ratio, crop top and bottom, to reduce side black bars, and icing on the cake, pseudo-spherical display distortion to simulate CRT rendering!

I sometimes wish HDMI had the abilities the SCART had, such as turning on or off the TV, automatically selecting input, signal nature, display ratio...

It does. It's called HDMI CEC.
