AM2R: Return of Samus

AM2R (Another Metroid 2 Remake) is a fan-made remake of Metroid II: Return of Samus in the style of Metroid: Zero Mission. It was released in 2016 by DoctorM64 and his team, and very soon after, has received a DMCA letter from Nintendo.

A few years after, multiple members of the community managed to reverse engineer the game and published unofficial updates, dubbed the AM2R-Community-Updates. Those fixed bugs and added new features like widescreen, added content planned by the original devs before they were struck down, and ported it to other platforms.
