Emulator

What steps will reproduce the problem?

1. Run Dolphin
2. Try configuring your emulator options
3. Try configuring the video options

What is the expected output? What do you see instead?
Config options and video options saved. Instead, the emu forgets all about
that, specially in video options.

What version of the product are you using? On what operating system?
r1643
Windows XP SP3

Please provide any additional information below.
Happens with Directx9 plugin and OGL plugin. I mark the options set
to "Fullscreen", "hack before r844" and stuff. When I go again to the
options, those marks are empty. I try doing it again, but it's no use. I
try checking if the files in the emu are read only, they aren't.
