30 years ago, Metroid was launched and until recently, fans of the series could revisit their nostalgia with a fan-made Metroid II remake. The remake, known as AM2R: Return of Samus recreated the GameBoy original but instead of playing in black and green, you had full colour.
We say recently because Nintendo has issued a DMCA takedown notice against the teams’ web hosting provider. While the AM2R website is up and running, they are no longer hosting the game files.
Friends: Nintendo has hit us (meaning, our website host) with a DMCA takedown notice. We can no longer host the AM2R file. Sorry!

Remember, if you plan on putting a lot of time and effort into developing a remake of a classic title, make sure you have permission from the owner to do so. Companies generally frown on fan remakes using their IP, of course, there are exceptions but Nintendo is not one of them.
