Games hang though (probably due to unknown ES call) -/dev/di IPC: Cleaned up code and fixed a bug (which I used to accidentally find out what I did), added Volume eject feature for VolumeHandler. -Partially documented Wii DVD cover flags. -Files opened in Wii Read-Write mode are now set to append. -Removed annoying overhead-ish "Idle" log message. As for /dev/di: Someone clearly didn't know what he was doing in that file. Someone freed memory which didn't belong to that file and then complained about a crash. Needless to say the problem is now solved. Big TODO on the /dev/di code though, ExecuteCommand is practically doing nothing but reading. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3365 8ced0084-cf51-0410-be5f-012b33b47a6e
