I used Wineskin to wrap Mass Effect (1). Wineskin helps me a lot with finding working and non-working versions of Wine and has worked very well for me in the past. With versions later than 1.3.23, (26, 27, 28 ) the game freezes after character creation. So I used 1.3.23. the problem is (still) that the mouse doesn't wrap in-game. This makes the game almost unplayable in combat sequences, when you can only move the camera in a narrow angle. You can simulate a "mouse lift" motion by moving the mouse quickly in the opposite direction and then moving it slowy in the direction you want the camera to turn, so, step by step, inch by inch, you can turn the camera around. Of course, this makes you a "sitting duck" in combat. MouseWarpOverride=force or =force-box don't seem to cure the problem This looks like a repetition of bug 6971, which is said to be fixed in 1.3.21. I didn't have the problem in Unreal 2. I tried to manually apply the patch given in bug 6971, but got the message that the code was already present. (I only patched Wine once, two years ago, and it might easily be my fault here) (There's also an issue with spoken dialogue becoming randomly silent after a few minutes of gameplay, but that should probably go in another thread.) This is really a pity, because otherwise the game is flawless and would get a Gold rating from me, but it it almost unplayable (and very exhausting) with that mouse/camera problem... Any help here would be very welcome...
