You can more or less access Spock through Lepton's ram (there is some hidden test mode on Lepton allowing you to do this). Mathieulh will tell more on this later if he ever get the time to clean up those sources. | You can more or less access Spock through Lepton's ram (there is some hidden test mode on Lepton allowing you to do this).

Spock command 9 key is used to decrypt UMD leaves stored in [[IDStorage]]. Those leaves are then used in Spock command 8 to decrypt the UMD master key (per disc key). Then this key is used in Spock command 10 to decrypt the UMD raw sectors. Each different PSP region seems to have its own set of UMD keys. | Spock command 9 key is used to decrypt UMD leaves stored in [[IDStorage]].
