FrostyTheSnowman released a new revision of his 360 Modification USB Drive(info).

What’s new/fixed in v1.6 Revision 4:
* Added support for Lite-On DG-16D2S Revision 83850C
* Added new ‘FrostyTheSnowman’ logo (thanks Shinho!)
* Replaced FirmTool (by Caster420) with LiteTool (by Klutsh) for Lite-On drives
* Removed DummyGen for Lite-On drives (no longer required thanks to LiteTool, thanks Klutsh!)
* Replaced ‘USB Drive Format Tool’ with ‘Bootable USB Drive Creator Tool’ (custom-made for me by Team Modfreakz)
* Typo fixed in HTML code (thanks yaywoop!)
* Replaced HIMEM.SYS with FDXXMS.SYS (better memory management)
* Updated the ‘Creating Your 360 Modification USB Drive’ tutorial
* Added a small note in the menu about not using spaces in the ‘directory name’ due to MS-DOS limitation (thanks Guentha!)
