This release has not been tested yet, but as the original Xbox DVD firmware mod released by the same person (Commodore4Eva) was working, chances are high this one will work too.

The modified DVD firmware has been released for the Toshiba-Samsung H943 Xbox 360 DVD drive (it will ONLY work on that drive - the Hitachi-LG drives will need their own modified firmware). Just like Commodore4Eva's modified Xbox1 FW, it will need raw dumps, some patching (security sector on ISO and DVD drive key on firmware) and DVD+DL recordable discs to work.

Release comes with tools to make this all as easy as possible. Also included is a 2nd firmware that will allow you to extract the security sector (what you have to patch on the raw ISO) from an original discs with your TS-H943 drive connected to a PC.

Here it is, the long awaited World first Xbox 360 backup firmware modification to boot all game backups!

Features:
- Boots all Xtreme Xbox 360 backups
- Boots all Xtreme Xbox 1 backups
- Boots all Xbox 360 originals
- Boots all Xbox 1 originals on Xbox 360
- Xtreme0800 extraction firmware enables drive to function natively under Windows without any hardware conversion/adaptors
- Use on Xbox Live at own risk

Technical details:
- Reads Xbox 360 security sector from PSN 04FB1F (Layer 0)
- Reads Xbox 1 security sector from PSN 605FF (Layer 0)
- Security sector must be extrated using Xtreme0800 360 firmware for Xbox360 games and Xbox 1 games
- Will not boot Xbox 1 backups made with Xbox1 605b 0800 firmware (maybe in future release)

Flashing your drive:
Advisable to make a backup of your dvd drive firmware first ("mtkflash r /m orig.bin"). Please make sure you hexedit the Xtreme.bin firmware (not Xtrm0800.bin firmware) to include your dvd drive key from your original firmware (usually at $4000-4200).
