Ultrastik mouse mode

[Roboman]

Is there a way of speeding up the Ultrastik mouse mode, aside from changing the mouse sensitivity in Windows?
Some emulators like Demul look for a mouse for games like House of the Dead 2, but the Ultrastik mouse mode is too slow to make it playable.
I wondered if you can fudge the Ultrastik maps or anything like that to make it faster, or is it impossible due to the nature of it being an analog stick emulating a mouse?
