Playing on a modded JTAG/RGH Xbox 360 allows you to go far beyond the original disc by adding custom songs and DLC that are otherwise difficult to obtain. Popular Content & Mods
Through tools like Onyx , players convert songs from other rhythm games (like Clone Hero ) to work on GH2. Note that performance may lag if you exceed roughly 200-250 custom songs in a single build. Installation Overview
This is the definitive way to play GH2 on RGH hardware. It is a massive "quality of life" mod that adds features like 120Hz support (for compatible monitors), custom themes, and the ability to easily add your own song packs.
You can export songs from other titles, such as Guitar Hero Encore: Rocks the 80s , directly into GH2 as bonus tracks.
