Initial port of zfreeze branch (3.5-1729)
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!!
