DVD Sector Scrambling(XOR) is done using Disk ID(gamecode + makercode), it is 6 bytes and of 16 Random Numbers to pick from to scramble the DVD sectors, done by the Disc Drive Firmware, it is stored on a on-chip ROM

DVD Sector Scrambling(XOR) is done using Disk ID(gamecode + makercode), it is 6 bytes and of 16 Random Numbers to pick from to scramble the DVD sectors, done by the Disc Drive Firmware, it is stored on a on-chip ROM, however for the MN102 Firmware it is stored on a on-board ROM chip that stores the firmware it is 128KB

Firmware for the MN102 System Controller is stored on a on-board ROM chip that stores the firmware it is 128KB
