redecomp is an index. Every entry points to a public repository on GitHub, built and maintained by its own authors. We don’t own, host or distribute any of these projects; the credit and the rights stay with their creators.
Decomps, recomps, native ports and engine rewrites ship code, not games. None of them include the original game: to play, you need your own legally obtained copy, and each project explains how to use it.
Game titles, logos and trademarks belong to their owners and appear only to identify each project. redecomp is not affiliated with or endorsed by any publisher or console maker.
We never link to ROMs, ISOs, keys, cracks or pirated files. If something here infringes your rights, write to lucca.bbiasoli@gmail.com and we will review it and take it down. Terms of use.
