All he did was open the advanced functions and use them.
I have no idea what tools are now in TKC's public section of it's downloads but I do know many tools I uploaded over the years are no longer there when we moved over to the new forum software.
I used to have a nice program that allowed repacking known cheats that AC systems banned based on MD5 hash...add a random bit here or there and the hash changed!
