OpenLRR is an open-source re-implementation of the 1999 real-time strategy game LEGO Rock Raiders.
Gameplay and features
As a re-implementation of LEGO Rock Raiders, OpenLRR requires a copy of the original game to already be installed on the computer, and its files must be placed in a working install folder.[2] The gameplay when running OpenLRR is largely unchanged from Rock Raiders; however, OpenLRR fixes numerous crashes, bugs, and issues found in the original game.[3] Most notably, OpenLRR adds a menu bar that allows for toggling numerous functions, including ones not possible in the original game.[4]
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.[5] 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.[6][note 1] Jordan started a forum thread to post his initial findings on the website Rock Raiders United on June 17, 2021.[5] Over the next few 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.[7]
By September 3, Jordan had organized most of the game's code into a more navigable state. Using DLL injection, he was able to replace several functions in the game's executable, allowing for new functions such as controlling entities in top-down view, multi-colored crystals, and resource monitoring.[7] (Prior to this, he had released some assembly patches created in Python, including one to fix a bug with certain sounds not playing.)[8] Jordan planned to eventually build on this concept to create an open-source version of the LEGO Rock Raiders executable, similar to projects like OpenRCT2 (which Jordan had previously contributed to).[9][7] A GitHub repository for the project, now called OpenLRR, was created on September 9, 2021.[10] The first build version of OpenLRR was released on February 18, 2022.[4] New builds were released during August and September 2022.[11][12] Further updates were made to its code through October 2023, though Visual Studio 2019 is required to compile these versions. The project is currently on hiatus, though future updates are planned.
