A1 issue...of sorts

[xzenox7]

I recently installed Armada 1 on a friend's laptop. However, instead of going through the installer, I simply copied and pasted the entire Star Trek Armada folder from my computer to the laptop. We played several games of Instant Action before we realized that we failed to put in the Armada CD, and yet the game worked perfectly without it. Anyone have any thoughts about how this happened? I'm not complaining; I'd like to duplicate the effect!!
