My friend uses Ubuntu and plays Cortex command a lot on my computer. But he can't get it working on WINE. Is there any fix to get CC working on Linux?

ZedDB discovered that it runs on WINE 0.9.37 onward, with OSS sound. It requires a hefty computer to run under emulation, though. There is a Linux version planned as CC becomes more feature-complete.

Your friend can install the newest version of WINE off the official site rather than Ubuntu's repositories.

I tried running it in WINE on Ubuntu a while ago, didn't work, unfortunately.

It would be helpful if everyone that try to run it in wine would post their results in the appDB http://appdb.winehq.org/appview.php?iVersionId=8116

Also as cambiogris pointed out you might need a powerful computer to run it. But as i have no other computer to test i don't know how powerful you need.
And like cambiogris wrote: If the Ubuntu's repositories don't have the latest wine version you can get the newest one at http://www.winehq.com

With an AMD X2 3800+ it takes about 55% of computer resources. Finally got it running in Ubuntu 7.04 with wine 0.9.38, see the other Linux thread here (link above) to see the details.

Emulation always requires an obscene amount of hardware capability.

Just dual boot. If you're using Linux, you should know how to do that.

Well WINE stands for: Wine Is Not an Emulator. So they don't emulate anything they just reverse engineer what is in windows so you can run it in linux.
But as this takes a lot of time and it's not complete and thus it´s not 100% effective or accurate.
But i agree with you. If you know that the games you play don't work well in wine dualboot if you want to play them without any problems.

Just dual boot is not a solution.
Plus, if you take a look, some games run fasters under WINE and Cedega that under XP (and, of course, under Vista).
