I'm pretty sure that mouse speed isn't a hardware thing, but a software thing, i.e. you can set the mouse speed in both directions using the int 33h API. I'm not sure if DOSbox emulates this API correctly, or that you have to load a "3rd party" driver like mouse.com.

Having a parameter you propose in the config file would thus imho be a Bad Thing (TM).

Is the mouse driver installed by default ? ; when opening DOSBox window from a linux console I have at the beginning the mouse active graphically in this DOS window ; when launching an application using the mouse if I click in the first window showing the mouse pointer desappears ; when using keyboard to choose option the mouse pointer reappears as a small losange that can move from character to character and behaves like in freedos except than when I quit the application I drop back in my Linux DOSBox window with no mouse ; I have to have to execute "exit" that leave DOSBox and get my mouse active again ; why all this ?

ask sdl people.
and read the readme especially the special keys.

The mouse speed is definitely way off in many of games. The vertical sensitivity in Lucasarts adventure games is about half what it was intended to be. Has anyone found a solution to this problem? If this problem were fixed, I would never have to use ScummVM again.

edit dosbox.conf
you can set sensivity there

Only in lucas arts games ? Hmmm well i thought the mouse was a bit slow in eric the unready as well. (vertical direction)

Perhaps not all LucasArts adventure games, but certainly the later ones. Compare running Full Throttle in ScummVM or on a legit DOS machine to Full Throttle running in DosBox and you'll have no problem noticing the difference. Same goes for The Dig. The vertical sensitivity is approximately half what it should be. The horizontal is just fine.

I noticed that the vertical movement of the mouse in Elder Scrolls: Arena is weird too - if you try to move too slowly in the vertical direction, the mouse cursor will get "stuck" on certain lines of the screen. Very annoying. I haven't tested with the latest CVS, nor with different sensitivity settings though.
