Is it true Wii can't do 256x240p resolution not even with homebrew?

    I heard somewhere that the Wii can do 240p but it can't lower it's horizontal res that low. Is that true? thx I notice retroarch doesnt have 256x240 but has like 332x240 or something like that.

    The Wii runs at 480p/480i/576i - anything else is resized to those resolutions.

    This is incorrect, the Wii can do 640x240p, otherwise HDTVs wouldn't have had problems with the Virtual Console. Or CRTs wouldn't give Virtual Console games scanlines. Plus there's all the fancy TVs that tell you what signal the TV is getting and is recognized as 720x240p which is correct.

    256, 320, or anything else gets filtered to 640 pixels but doubling them to 512 or 640 gives you a sharper image, there are other resolutions like 384 or 352 that can't be doubled obviously but output is still decent and sharpish.

    So it's not a true 256x240 image but the difference in quality is so small that it doesn't really matter and the pixel aspect ratio on the SNES is more or less the same(actually it isn't but the stretch from 256 to 4:3 makes it like that) as the Wii so you're getting a very accurate image.

    Yeah, noooo... Since when is that the case? Ever heard of scaling? :)

    240p was also needed to preserve GameCube backwards compatibility. First used by The Legend of Zelda Collector's Edition, and Mega Man X Collection.

    I already said there was horizontal scaling to reduce the amount of filtering, so why would I not have heard of it?
    If there were vertical scaling you would not get a progressive field with composite or s-video, the problems with HDTVs, scanlines in CRT TVs, etc.

    Here; eke eke himself wrote several times about the process:

    So essentially the 720x240 mode is a "necessary evil" that allows for 480i and springs from the frame buffer size, fair enough. I did not know that you could use it as an actual display mode, I thought the system was limited to what the display settings allow. Thanks for the clarification. ;)

    The Wii can do 240p, but many TVs cannot display that resolution over Component. It's a problem with the TV, not the Wii. A very common problem though, which is why most emulators on the Wii output as 480i/p as standard.

    You can force most emulators to output native 240p. Genesis Plus GX and Retroarch, for example.
