alright, maybe i am going out on a limb here, but freeway ultra is written in c, which can be compiled for linux. It is a front end for mplayer, which is also on linux correct? So would it be possible to port freeway to linux?
Well, you will be using it on your car-puter wont you? unless you are planning wlan/internet connectivity, any ol' xp installation will do..
i dont know about your xp, but mine just stops working after the 30 days, it wont logon or anythingl.
any corporate edition is activation free. just find one of those and any old serial. dont think anyone will be questioning you about that
