Freecraft doesn't play Starcraft. It's a fairly utilitarian Warcraft-alike RTS engine (and example game) with anemic developer support under constant legal threat from Blizzard (Blizzard has actually shut down the project with a cease and desist).
I'm not aware of the possibility of porting, because I can't find the Freecraft source, but I remember Stratagus is portable.
Both of them are designed for much higher resolution machines, so a lot of UI hacking will be necessary to make it even vaguely usable.
