A new patch is now available for Guitar Hero III: Legends of Rock, updating the PC edition of the music/rhythm game to version 1.31. The patch is available from the Aspyr Website and mirrored on AtomicGamer, FileFront, Gamer's Hell, and The Patches Scrolls. Here's word on the new version:

This optional patch fixes an "Emulator Detected" error that appears on some machines AFTER APPLYING THE 1.3 PATCH. This patch does not affect gameplay in any way and only resolves this emulation issue.

This patch is to be installed only after applying the 1.3 patch. The in-game version number will not change once the 1.31 patch is installed.

This patch is for PC only. The Mac 1.3 version is unaffected by the Emulation problem.

PLEASE NOTE: This will only resolve Emulator Detected errors that occur after the application of the v1.3 patch. If you have had these errors before applying the 1.3 patch, this patch will not fix the problem.
