How are prefs stored?

I managed to render my install unusable by switching full-screen mode off. The window is so large that the menu on the main screen isn’t visible. I can’t find any kind of preferences file or registry keys to nuke in order to reset this? I tried uninstalling/reinstalling, but no luck - still windowed and too large.

I have failed terrifically.

they are under \MyDocuments\My Games\Gratuitous Space Battles\prefs.ini
Its text, just reset the windowed to be 0.

Oh. Durr. Crossover Games decides that it would be a grand idea to link My Documents/ to ~/Documents…that would be why I couldn’t find it.

Thank you!
