Decompiled games you can play

Decompiled games are games whose code fans have rebuilt as readable source code, function by function, until it compiles back into the original program. From that source, they can make native ports for PC, phones or browsers. The Halo: Combat Evolved browser port and ProjectCane, the native PC port of the first Sly Cooper, both started from decompilations.

A decompilation takes years of work, but it gives the most freedom for fixes and mods. A recompilation is faster but keeps the original program’s structure. This list shows decompilation projects you can actually play, with what each one needs from your own copy. Projects that only rebuild code without a playable port, such as the Fallout: New Vegas decomp, are explained on their game pages. Our guide on recomp vs decomp vs emulator explains the difference.
