Where can I get the key? Another problem is if someone decides to mod these games after many years and no one has the key by then and there's no place to find the key, how will they mod the games? Is there a way to find the key from the game's exe or anything? I think this key requirement is going to be a big issue after some years. Unless there's a way for users to find the key from the game themselves, the key's gonna get lost at one point, destroying the modding capacity of these games. Also I tried googling around and haven't found any explanation about why the key is required to begin with? Also how did Cg file explorer managed to view the files without the need of key- I'm curious about that.
