ex: holding 9 down would keep telling the player to move north and east over and over again.
problem is, mousekeys is too slow for this to work. so it takes like two seconds to get going that way.
i found another mouse emulator (http://www.geocities.com/pronto4u/mouseemulator.html) that lets you change the speed by entering new values into its section of the registry.
If you backup/copy the fastest reg file and change it to something like this...
(edit: changed numbers)REGEDIT4
[HKEY_CURRENT_USER\Software\RH Designs\Mouse Emulator]
"Mouse Delay"=dword:00000010
"Mouse Base Speed"=dword:00000100
"Mouse Max Speed"=dword:00000100
(edit2: changed numbers again)
...it will move the mouse fast enough to give you diagonal movement.
But it's unresponsive, hard to touch things, and sometimes goes in the wrong direction. so it's pretty useless unless you're playing a game with lots of open spaces. since the mouse emulator uses the numpad (5 is down for some reason, 1 is shoot, 2 is autorun), you can switch between the arrow keys and the numpad when you want different styles of control.
If there's a better way to get diagonal movement, I want to know!
