This is probably a bit naive on my part, but Once you buy a game, isn’t it yours to do as you please, including hacking the software? You void your warranty, but what’s the issue otherwise? You’ve effectively paid the license fee when you buy the game. I thought the problem comes when you start doing software modifications with licensed clips or sounds you haven’t paid for and then offering it to others, free or not. This notion that stern could detect a change you’ve made and somehow disable your game doesn’t seem right.
What would stop someone from instead of sharing their revised code to telling others how to do it themselves?
