OmniDrive

Description

OmniDrive is a firmware modification for MediaTek MT1959-based optical disc drives manufactured by Hitachi-LG Data Storage that enables features that allow for better, more complete reading of discs, including proprietary game discs.

Features

Lead-in/lead-out reading for CD/DVD/BD and derivatives.
Raw sector reading for CD/DVD/BD and derivatives (2352 bytes/sector for CD, 2064 bytes/sector for DVD, 2072 bytes/sector for BD).
Custom READ DISC RAW command to read discs, with flags for FUA (bypassing cache), raw addressing (MSF for CD, PSN for DVD/BD), and descrambling (for DVD/BD).
The ability to read various proprietary game discs (see table):

Building

Dependencies

CMake
ninja
arm-none-eabi-gcc toolchain
armips
Python 3
pycryptodome

Instructions

Put the stock LG BU40N 1.00 and ASUS BW-16D1HT 3.02 firmware files in the firmware folder. The files should be named the following and have the following checksums:

Filename	CRC32	MD5	SHA-1
HL-DT-ST_BD-RE_BU40N_1.00.bin	`E3C1A315`	`EDB28FCD7A239281ACE26A468D382A9C`	`9C48677B155154D24A3B95A32B4A29CA02FF40B3`
ASUS_BW-16D1HT_3.02.bin	`84000B21`	`97F0EEABD0B675B4363B2C4749226016`	`F8DF5B579F25DA8D4E5AA5EF79F3005DAC5EB8C7`

Create a build folder and run cmake -G Ninja .. from the build folder.
Run ninja. The patched firmware files should be output in the patched_firmware folder.

Flashing

Currently the recommended method to flash the drives is to use sdftool which comes as part of MakeMKV. The BU40N firmware should work with all slim drives and the BW-16D1HT firmware should work with all desktop drives.

Redumper has initial support for flashing, but cannot cross-flash drives yet.
