Re: [hatari-devel] IKBD_Cmd_SetMouseScale in the game "The Sentinel"

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Hi,

I've tested rainbow II multimedia (winuae CPU).
It's really much better with the patch :
The mouse goes perfectly from the upper to the bottom of the screen, 
that's really good.
For the left/right movement, there's still a little problem : the mouse 
doesn't go to the extrem right of the screen, it goes out a bit before 
(a precision problem ?).
The patch is good for rainbow 2.

For crown of creation (oldCPU), the problem seems to persist on the X 
axis of the mouse (the Y axis is useable).

Best regards

Laurent
