How to run HALO 2 under Windows XP

[hssemichi]

open up a cmd shell (start -> run -> cmd -> enter) and navigate to the folder where you extracted loader.exe (with 'cd directory').
then type

loader.exe LetterOfDVDROMDrive:\StartUp.exe

same procedure for starting the game after copying dll's - just type

Loader.exe "C:\Program Files\Microsoft Games\Halo 2\halo2.exe"

(depends on operating system language)
