How to debug a program spawned by another program?

[jonwil]

I did some further analysis and it seems to be passing values in environment variables. However if I set those environment variables to the same values manually, it doesn't work (it gives me an error related to the copy protection and wont start the game)

The programmers at EA have obviously put a lot of work into making it hard to do exactly the thing I am trying to do (get the actual code behind the protection system into a debugger)
