Emulator

(the fullscreen button is esc. a silly move if you ask me)

Escape just closes the emulator. Have a look at the code (line 59):
http://code.google.com/p/dolphin-emu/source/browse/trunk/Source/Plugins/Plugin_VideoDX9/Src/EmuWindow.cpp

when i go to full screen the emulator just close and if I'm even able to get to full
screen when i try to go out guess what the emulator close again

I fixed it here, I think it can be done better, but it definitely works (for all
windows builds):

Oh, this only works with the Escape key, I forgot to add Alt Enter support, but I'm
sure you can change it to easily reflect the same changes.

updated the patch a bit, much cleaner, made it into it's own function, much like the
OGL plugin.

Issue 1491 has been merged into this issue.

Something else broken with fullscreen toogle: 2D stuff will start being pixelated
after you toggle, as in not smoothed out, same with some textures, the walls in
Metroid Prime looks like the walls in Dungeon Keeper, if you walk right up near them.

Yeah, this is an issue with my patch, but what's strange is that if you re-size the
window, it will fix it :/

Maybe throwing another D3D Reset at it after it's done re-sizing would fix it? I
dunno why it does that...

Still an issue?

On the SVN, Yes, it still just closes the emu.

Line 75, It's not a bug, it's coded to close the emu when you press Esc.

As far as my patch goes... it is very unstable. There's definitely a better way to
do it. It hardly even works anymore... I haven't updated it since I posted it here,
and there have been some significant modifications to how it renders now. I'd have
to re-write the patch to fix the crashing and blank screen problems that it has now.

This issue was fixed to the better for a while, but now toggling to fullscreen
doesn't work at all. Alt + enter do nothing, pressing fullscreen on the Dolphin
toolbar do nothing, Esc crashes the emulator. (r4590 x86)

Yeah, it seems like someone has disabled alt+Enter to full screen :(
