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

[Nicolas Pomarède <npomarede@xxxxxxxxxxxx>]

Hello

there seems to be a problem in the game "The Sentinel" by Firebird.

Moving the mouse is extremely slow ; the only unusual thing is that they 
set absolute mouse mode to a very big area, which seems to be 
"compensated" by mouse scale command :


IKBD_Cmd_AbsMouseMode 2560,3072
IKBD_Cmd_SetInternalMousePos 1280,1536
IKBD_Cmd_SetMouseScale 8,16
IKBD_Cmd_SetYAxisDown


Then the game read the mouse's position with ReadAbsMousePos.

eg :

IKBD_Cmd_ReadAbsMousePos 1280,1536 0x0
IKBD_Cmd_ReadAbsMousePos 1280,1536 0x0
IKBD_Cmd_ReadAbsMousePos 1280,1536 0x0

Strange thing is that IKBD_Cmd_SetMouseScale is storing values in XScale 
and YScale, but it's never used anywhere to scale deltaX/Y values.

Thomas (or anyone else), do you remember if that's an old part that was 
never implemented ?
