Sony working to stop UMD loaders?
Personally, I think UMD loaders are only really used for piracy. I've heard excuses that it extends battery life, but that's BS - if you're running UMD images, you probably don't own the games :) Let's not pirate, folks! It hurts us all! -Auri
Reports are now starting to come in that Sony is starting to get a little tricky for those of you who run UMD backups via Memory Stick. In their latest release, Outrun 2006: Coast to Coast, there appears to be absolutely NO PRX files or folders located on the UMD. Basically, it's going to be more difficult to decrypt the PRX files with the currently available homebrew application, and UMD Loaders such as Run UMD 2.0+ Game Loader and MPH 2.0 Game Loader may run into issues as well.
