Hey there! 34 hours? What the heck :D
In theory, every oder version can be built and run via compiling the source. Is there a particular version you would like to have? Just building every version would take forever (and uploading as well, my internet speed is abysmal).
Sorry for the wait! You can download 2.1.1 here: http://games.d-cay.de/friendlyfire-2.1.1.rar
