Wiimote Project

Ive been noticing a fair few people having issues with WW0.2 and all the mods based on these. Its always under vista, and involves the mouse control not working but calibration does.

Now the bit which threw me for a while, is that its actually not with Vista, but with Vista64bit. Which im guessing some people dont even know that they are running due to it being preinstalled on their computer.

Anyway, the problem lies in the fact that the pointers in x64 windows are 8bit pointers, rather than 4bit in x32. The INPUT struct is therefore offset by the wrong amount, so the mouse events fall into the "type" bit, and is ignored.

The quick fix for it is to simply replace this code:
[StructLayout(LayoutKind.Explicit, Size = 28)]
        public struct INPUT
        {
            [FieldOffset(0)]
            public int type;
            [FieldOffset(4)] //*
            public MOUSEINPUT mi;
            [FieldOffset(4)] //*
            public KEYBDINPUT ki;
            [FieldOffset(4)] //*
            public HARDWAREINPUT hi;
        }with this
[StructLayout(LayoutKind.Explicit, Size = 28)]
        public struct INPUT
        {
            [FieldOffset(0)]
            public int type;
            [FieldOffset(8)] //*
            public MOUSEINPUT mi;
            [FieldOffset(8)] //*
            public KEYBDINPUT ki;
            [FieldOffset(8)] //*
            public HARDWAREINPUT hi;
        }
The longer term solution is a bit more complex, but because of the oddness of C# you cant just declare sizeof(IntPtr), and im trying to figure out a better solution than declaring two structs and using which ever one is appropriate for the platform.
Ill try and figure out a way to modify the struct sizing on load.
