Hacking Upscale games upto 1080p.

[WildWon]

Ok, reopened. Don't do it any more. And keep on topic.

Nobody is really arguing over it though, are they? I think most of us realise it's not possible. I agree though, seeing as it isn't possible, there's not much point to this thread remaining open.

This guy has got his answers. No need to keep this thread open.

Pal is 720x576

wadzinsky is correct

upscaling = resizing

hence why 640x480 (default pal50 tv resolution) can look horrible on some big ass LCD TV

I've noticed no improvement in my DVD movies watching them upscaled by my PS3 vs watching them on a plain old Sony DVD player. It's purely just a marketing scheme in my opinion.

Then you need your eyes tested.

waoh topic got bumped? Isnt the wii's frame buffer whats limiting the possibility of higher resolutions? (but then most games wouldn't run that well i guess except galaxy....thats a pretty well optimized game)

If the 480p were upscaled correctly, it wouldn't look too bad. People go for size, plasma or lcd, 24p support and stuff when choosing a tv and not for good upscaling capability. No people looking for it -> it's underdeveloped and tvs with it just don't exist.

Watch a DVD that is upscaled by a ps3. And then watch it a DVD player, upscaled by your tv. Only if it's both times the same quality, you can say you have a good tv. (and if it's good for other reasons of course)

Word, what good is a big, hi-def screen if the picture is arse?

the wii framebuffer is stored in main memory, so the only limitation is memory size, you could have a 1600x1080 framebuffer in memory if you want.
The problem is that the Video Encoder chip inside the Wii, which produces the video signal from the framebuffer , as far as we know, cannot ouput anything better than 480p, so it's a hardware limitation that can not be solved without hardware mod or signal conversion (upscaling) between the Wii and TV.

XFB is main memory, and can be as big as you want. EFB on the other hand (what GX uses) is on the chip and is indeed very limited in size - it's not big enough to hold a full anti-aliased 640x480 frame.

 

[Jacobeian]

afaik, EFB size is only a rendering limitation, you can do as much rendering+copy to XFB as you want and fill a bigger XFB in several passes by specifying correct destination locations ...

I'm sure many games are doing this in order to use the full horizontal resolution(widescreen support) or for multiplayer split screens

I'd like to see you find a game that uses more than 640 horizontal pixels, since that's the maximum width the SDK supports.
