Super Mario Bros. X2

The SMBX2 was built from multiple parts, and I call this in Russian as a "сборная солянка":

• The copy of SMBX 1.3 executable built by Redigit in 2010'th year. It was closed-source until February 2, 2020, see the post here: https://www.supermariobrosx.org/forums/viewtopic.php?f=69&t=25160. From that sources, I built the TheXTech project.
• The LunaLua hacking library (lunadll.dll, lunaloader.exe, and "lunaloader-exec.exe") from this repository: https://github.com/WohlSoft/LunaLua, GPLv3 license
• The code for the Launcher is here: https://github.com/WohlSoft/LunaLua/tree/master/LunadllNewLauncher/SMBXLauncher (at the LunaLua repository)
• The devkit for Editor and dev tools is used from the PGE Project which is an independent FOSS project of a game engine and the toolkit: https://github.com/WohlSoft/PGE-Project
• The SDL2 library used for the sound output and for the game controllers support, https://hg.libsdl.org/SDL/
• The music and sound processor library is the SDL Mixer X (SDL2_mixer_ext.dll) is from this repository: https://github.com/WohlSoft/SDL-Mixer-X
• The big set of lua-scripts (the rest of SMBX2 internality was coded in a pure lua), all sources included with every released game copy.

All components were maintained independently, and the WIP copy of the game is developing by the cathedral model (opposite to the bazaar model where the repository with all WIP changes is published).
