The current version of the game is Version 1.0.2. This update added Rock Hard Mode, and rebalanced multiple things to generally make the game harder (in particular, Promos cost more and give less Fans). So, aside from runs on Rock Hard Mode, Version 1.0 is faster.

This download includes all game files, except the EXE (which is unchanged between versions, and should make this legal!). Extract them on top of a game copy, replacing all original files. (If it doesn't ask you if you want to replace anything, then you're not extracting it in the right place)
