Heya haven't seen you for a while Bio!
Anyway, there is a Win32 emulator (they like to call it a windows compatible layer) for Linux. I think you can get it at http://www.winehq.com. There are also a lot of new Linux distro's which support a ton of Windows programs (Xandros, Lindows, etc).

Oh yes, you might need another debugger than the one which comes with the standard install. I'd ask around at the site for those. JCS does run with the standard debugger though.
