the idea is interesting, but I really wonder how that works, especially for 2D elements. the resolution is fixed at 256x192 and much of the hardware is designed with that in mind.

so apparently all I'd need on my side would be changing the aspect ratio of the screens I guess. mh

might make more sense to do that once we have upscaling, tho.

for 3D graphics, you can detect whether the matrix is 'close enough' to a typical projection matrix, and tweak it so the aspect ratio is 16:9 or whatever you want. I tried a quick hack for that a while ago, and it worked, but a couple issues:

* games tend to be made with the original 4:3 aspect ratio in mind, which means things might not render right on the screen edges. (often they use their own way of determining what is onscreen instead of using the boxtest feature)

* as far as I can see, the widescreen shit is still rendered at 256x192, which results in a loss of quality for 2D graphics. on the other hand, rendering them at a 16:9 resolution (340x192 or something close) would require a bunch of hackery in the whole rendering pipeline.

* it's also complemented by game-specific hacks, to get around the aforementioned issue, scale 2D graphics accordingly, etc

widescreen hacks that consist into AR codes can be used with melonDS 0.9. the only remaining issue afaik is that we don't have a 'stretch screens' mode that would complement it.
