Just got the new cx demo. Mass Effect still requires mouse patches.
dinput patch no longer works so here's a new one along with the same old winex11 patch uploaded again.
dinput.dll[unreal_engine+wine-1.1.42].diff
winex11.drv.diff
I'm not a software person but it looks right to me.
Tested all ok, although I did notice I had to select hardware mouse in Mass Effect settings or the mouse would disappear.
Can't remember if it was like this before haven't used it since last demo of xover.
Here are binaries compiled on Fedora 12 X86_64 for 32bit wine-1.1.42
dinput.dll
winex11.drv
Edit: For Crossover 9 you need to put user32.dll from wine source in binaries folder as well
user32.dll
Whack em in your Mass Effect/Binaries/ folder and your good to go.
