Development

OpenLRR development began in 2021 after programmer Robert "trigger-segfault" Jordan began looking through the LEGO Rock Raiders executable assembly to figure out how the game's config file syntax functions. Jordan used Ghidra to decompile, identify, and label code from the LEGO Rock Raiders executable. The decompilation focused on the September 27 English version of the game's executable (the "Masterpiece edition") as it was considered to be the most stable and widely-used version of the game.[2][note 1] Jordan started a forum thread to post his initial findings on the website Rock Raiders United on June 17, 2021.[3] Gods98[4]

The OpenLRR GitHub repository was created on September 9, 2021.[5] The first version was released on February 18, 2022.[6]

Notes

  1. ↑ The English version of LEGO Rock Raiders has three known executable versions: a September 25 version, a September 27 version (commonly called the Masterpiece edition as it was the version used in LEGO Masterpiece-labeled released of the game), and an October 12 version (which includes SafeDisc protection).
