Need help portablizing Caves of Qud for personal use

Basically, to make the steam version of Caves of Qud portable, all you need to do is knock out the steamapi.dll and use the commandline parameter -savesomethingorother with a location. / will start at the root of the current drive. The trouble is, I'd like to register the bat file, or possibly even cmd, with the start menu so that I can launch it directly from portable apps menu. Please help.
