I've largely got the mouse working with some trial & error. I'm using the following code modified from the Windows and X versions: int HorizPos = (int)VIDC.Horiz_CursorStart - (int)VIDC.Horiz_DisplayStart*2; int VertPos = (int)VIDC.Vert_CursorStart; VertPos -= (signed int)VIDC.Vert_DisplayStart; int xdiff = (msg->MouseX - 20) - HorizPos; int ydiff = - (msg->MouseY - VertPos); if (xdiff > 63) xdiff=63; if (xdiff < -63) xdiff=-63; if (ydiff>63) ydiff=63; if (ydiff<-63) ydiff=-63; KBD.MouseXCount = xdiff & 127; KBD.MouseYCount = ydiff & 127; msg->MouseX and msg->MouseY are the co-ordinates of the Amiga mouse pointer - this has an origin of 0,0 at the top left. If I modify the xdiff and ydiff maximums down to 1, the RISC OS pointer seems to follow the Amiga pointer correctly, if I move it in one pixel increments. However, when the two pointers are within 1 pixel, the RISC OS one seems to jump one pixel other to the other side. This wouldn't be a problem, except when the maximums are increased back to 63, it still does it but jumps 63 pixels the other side of the pointer when it gets within 63 pixels! It appears to affect both X and Y. I'm tearing my hair out over this one, and it's probably obvious but I can't see it - anyone?
