The last heuristic wasn't quite smart enough and had a few
false positives in Mario Kart: Double Dash and Metroid prime 2.
Now we only activate if the game is rendering a 16:9
projection to a 4:3 viewport.
Someone suggested on IRC that we should make a database of memory
locations in GameCube games which contain the 'Widescreen' setting
so we can automatically detect if the game is in 4:3 or 16:9 mode.
But that's hardly optimal, when the game actually tells the gpu
what aspect ratio to render in. 10 min and 6 lines of code later,
this is the result. Not only does it detect the correct aspect ratio
it does so on the fly.
I'm a little suprised nobody thought about doing this before.
- Calculate ZSlope every flush but only set PixelShader Constant on Reset Buffer when zfreeze
- Fixed another Pixel Shader bug in D3D that was giving me grief
Initial port of original zfreeze branch (3.5-1729) by neobrain into
most recent build of Dolphin.
Makes Rogue Squadron 2 very playable at full speed thanks to recent core
speedups made to Dolphin. Works on DirectX Video plugin only for now.
Enjoy! and Merry Xmas!!
