- Removed all scetool dependencies; - Implemented a key vault to manage PS3 keys internally; - Implemented SELF decryption; - Improved PKG handling. Notes: - NPDRM SELF files (EBOOT.BIN) can also be decrypted. A valid matching RAP file must be placed under the dev_usb000 folder. - The source code is considerably commented and several debugging functions were also added in order to aid anyone who wishes to contribute to the engine.
