- Updated AES and SHA-1 source code; - Fixed a few code warnings; - Implemented EDAT/SDAT decryption. Started SPURS implementation: - Added an internal SPURSManager class draft; - Added several drafts for cellSpurs functions. Implemented key.edat decryption in sceNpDrmIsAvailable: - NOTE: Currently, the decrypted key.edat is stored under dev_hdd1/titleID and the user must replace this file in dev_hdd0. This behavior will change in the future as it's currently intended for controlled testing only.
