I don't know about the online checks as my desktop doesn't have an internet connection unless I run an ethernet cable to it. All I know is that the CoH:ToV v2.600 NoCD crack does not remove the media validation for CoH:OF v2.600. It loads, then asks for the disk. Obviously I can use the actual disk, but currently the only way for me to play the game without having the disk in the drive is to use the mini image.
The readme for the v2.600 crack says 'I made the crack just using a hex editor lol and it has been tested for 15 mins and it worked correctly', so if it's that quick to crack it should be a simple job to remove the OF CD check from the file as well. I would do it myself if had any clue about how to crack, but I don't.
