The GOG.com release of Insane (stylized as '1nsane') is a 487mb installer
executable, which installs and runs correctly using a winxp bottle profile.
The GOG version has been patched to the latest official version 2.0 (1.0.1.2)
The game's main menu is hardcoded to a 640x480 screen resolution - if your
display hardware is not capable of natively displaying this resolution (in
the case of widescreen 16:9/10 aspect screens), you will have to enable the
'Emulate a virtual desktop' feature use winecfg - see tips&tricks if you need
help with this.
A silver medal straight out of the box - not enough gameplay yet for gold,
but it looks like it might end up that way.
Cheers!
