Proto:Guitar Hero

This page details one or more prototype versions of Guitar Hero.

The September 3, 2005 prototype build of Guitar Hero was leaked as part of Project Deluge, released through Hidden Palace's website and archive.org on March 20, 2021. Nothing was known about this build prior to its release, although other beta versions of this game had been seen in marketing material before.

General Differences

  • This build is DEBUG ENABLED, and the majority of GH2's debug buttons work when connecting a keyboard via usb.
  • The HOPO threshold in this version of the game is stricter than retail; 159 ticks (1 tick less than a 12th note), vs 170 in retail. Charts where this adjustment is particularly easy to spot are You Got Another Thing Comin and Texas Flood on Expert.
  • Notes that follow a chord and have the same color as the chord's lower fret can be HOPOs in this build, unlike retail where they are always strums. A good example of this is Heart Full Of Black on Expert's orange strumming section.
  • Whammy rate is different in proto build, gives you less Star Power.
  • The bug in retail where the 2nd note of the song always appears as a strum, even if it is a HOPO, is NOT in the prototype.

Major Bugs

  • Letting a demo play then trying to select a band crashes the game with an "Index Too Big" error
