Homebrewers create DRM to prevent homebrew theft
The homebrew community isn't all about stealing and emulating games. There are tons of original applications developed by hard-working coders all the time. In a somewhat ironic move, a programmer at QJ.net called Xart, has created a DRM (digital rights management) system that encrypts his games, so they can't be altered. DRM is the technology behind services like Apple's iTunes store, or Sony's PSone download service, which allows downloads to have more security. With encryption in place, developers can be more confident that their work won't be toyed around with, and they'll get the credit they deserve.
