Emulator

This is the same as Zelda Twilight princess
Using 640x480 should fix it.

Nope, this square is always 1/4 of display on each resolution.

just like twilight princess, it always take 1/4 of the display, and bloom is
misplaced, disabling copy EFB to texture remove these glitches, but also removes the
HUD and some others effect :(

Huh, I think I've found something !

in OpenGL plugin's TextureMngr.cpp from line 375 to 376
there's two lines :

int w = (abs(source->right-source->left)/mult+7)&~7;
int h = (abs(source->bottom-source->top)/mult+7)&~7;

changing that to :

int w = (abs(source->right-source->left)/mult);
int h = (abs(source->bottom-source->top)/mult);

Fix the bloom offset in games like Twilight princess and also fix the offset that you
can see in the 'blurry square' of Wii Sport so it looks good now, also, in native
res, the blurry box can't be seen, as it doesn't blur anything, and is no longer
ofsetting, but I've yet to find any way to fix its scaling however...

(P.S: this was quite unexpected fix :p, and if anyone can explain me how this '&~x'
thing works, it'd be nice, I actually removed it cause I couldn't find any doc
explaining that.. :D and it turned out better :p)

Nice job! :D
Could you send mi Revision with these 2 lines changed or only OGL plugin?
I would like to see how it looks like now.
Really, you deserve for a big cold beer ^^

you can find a couple of screens (and OGL plugin too) in this post :D :

nice fix, Ill test and get it submitted tonight. this might fix mario kart wii as
well :D

looks great, omegadox commited it. if you want svn write, just send an email to
hydgard or F|RES, or otherwise contact them somehow ;)

alright,
thanks for the explanation :)

Is still present in 4418 even with the Software plugin.

( Issue #1443 -> #828 can also be seen present )

Still present in later revision r4656.
Here some more info:

problem on upper left corner, exactly 1/4 of the screen. The image in this area looks
no scaled to upper resolution, like the remaining of the area.

BTW using D3D. No problem in OGL

As of rev4800 I can still see the blurry square in Zelda:TP, in both DX9 and OGL.

Using ATI 5770 with Catalyst 9.12.

The link to the OGL one doesn't seem to work, so here's a new one:

a simple work around to offset box (in Twilight Princess at least) is to use free look
(opengl plugin/advanced/select free look) press S 2 times and the box goes away along
with the bright yellow around the bottom of the screen. This has to be done on every
play through. Basically it just zooms out the camera 2 steps which for some reason
fixes it.

These issues are not related whatsoever.

Anyway, since you're here, I can more or less explain the situation. The reason your graphics card does not support the minimum requirements for the new LogicsOp code. In order to get correct behavior on supported devices, the old hack was removed, meaning that outdated drivers/graphics cards have issues. You can use another backend, older builds, or maintain the hack yourself on a fork. We don't like maintaining old hacks because it increases code complexity and makes it harder for new features to be added. Sometimes this can be frustrating for people on older computers/operating systems, but, in order to keep getting emulation better overall, it has to be done.

Created bug #11466 to address this issue.
