84611502c6 copy only modified pixels to RDRAM 
0 is used as test color. If pixels are 0 they are not copied. This fixes
the crash in Donkey Kong 64 (E) issue #355

142ad0bc3c code refactoring to support async buffer reads 
Copy of color buffers is now always done in gDPFullSync. There are no
known disadvantages only advantages. Quake 2 will run faster

dc3da06a68 as suggested by gonetz buffers are now also copied after the buffer changed in SetColorImage command 
now the copy auxiliary option also works if a buffer is used in the
current frame

c661ace24e Replace RSP.DList by OGLVideo::getBuffersSwapCount() 
RSP.DList does not count the dlists, it counts the buffer swaps.
Thus it is replaced by counter in OGLVideo.

2483f03159 Add CopyToRDRAM modes to Config: disable, sync, async. 
copyToRDRAM option can take 'async' value.
copyDepthToRDRAM is still sync mode only.

24885907d8 Add hack_ZeldaCamera to fix camera in Zelda MM, #577 
The game copies current frame buffer to the area, which initially allocated for depth buffer.
Game read camera data from that area, not from normal frame buffer.
That's why 'copy color buffer to RDRAM' option does not help there.
Special code needed to process that. Looks ugly, but works.

0735bd0372 modify fingerprint validity checking method 
In Zelda OOT the CPU applies a filter on the framebuffer texture. If we
write a small amount of data at the beginning the CPU won't change our
specific values
 2015-08-17 21:56:59 +06:00

e0face5f86 use unique values as fingerprint 
this works much better
But sometimes Zelda writes values not only under but also over the
fingerprint, Link's model is lost again

e617177958 fix problem with validity ckecking in Zelda OOT

68941f6cbe Optimize frame buffer copy to RDRAM: 
read from pixel buffer one time per pixel.
Old code does 4 reads from the pixel buffer per pixel.

The optimization makes color buffer read circa 4 times faster.

Thanks Lars Bishop for finding the sources of the problem and for suggested solution.
