Here's the newest version of Liberty (11947) compiled by me. It includes support for Halo Reach as well as Halo 3 and Halo 3 ODST. Since this is an unofficial release do not contact the authors for support.
This is the first version with full, working ODST support. Download below.
Credits to AMD, Xerax, ThunderWaffle, and XenonDev for this amazing application.
