Main Issues: DX11 is functional with a ~2MB/s mem leak. OpenGL/DirectX9 have a black display while game runs. (DirectX 9 flashes good display on emulation stop) Too many virtual function calls. (once everything is working, I will work on removing them) Won't build on non-Windows in its current state. (mainly EmuWindow will need changes for Linux/OS X) Probably other stuff. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6219 8ced0084-cf51-0410-be5f-012b33b47a6e
