Gameplay and features
Development
Development of OpenLRR began in 2021 as a decompilation project by programmer Robert "trigger-segfault" Jordan, who wanted to look through the LEGO Rock Raiders executable assembly to figure out how the game's config file syntax functioned.[2] 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.[3][note 1] Jordan started a forum thread to post his initial findings on the website Rock Raiders United on June 17, 2021.[2] Over the next several months he continued work on decompiling and identifying all the functions, global variables, symbols, and data types in the assembly. Jordan's work was made easier by the release of the source code for the Gods98 game engine, which LEGO Rock Raiders uses, after it was discovered on hard drives formerly owned by developer Data Design Interactive.[4]
The OpenLRR GitHub repository was created on September 9, 2021.[5] The first version was released on February 18, 2022.[6]
