Explore game decompilation, source reconstruction and reimplementation projects. Compare target platforms, sourced progress and ways to contribute.
Completed means every reported percentage is 100%, or the project is explicitly marked complete. Each measurement keeps its original scope; code matching alone does not describe every part of a project.
Projects are sorted by the latest recorded repository star count. Stars indicate interest, not completion. Missing counts remain unknown.
