Edward Findlay has released a free fan remake of Konami’s Castlevania 2 on the PC, called Simon’s Quest Rebitten. This remake comes with native controls for the PC, as well as some improvements. For instance, it features a day/night cycle and boss fights.
Now what’s really cool here is that Findlay has created various remakes for other classic NES games. For instance, you can download a remake of Ninja Gaiden, as well as a remake for Splatterhouse 4.
Additionally, you can find a remaster of Faxanadu. This remake is also three times longer than the original game, so make sure to at least give it a go.
You can download all these freeware games from here. Needless to say that even though these are free fan remakes, all of them use copyrighted material. What this ultimately means is that they may be taken down really soon. Thus, we suggest downloading them while you still can.
Lastly, I’ve included below some videos from some of them so you can get a better idea of what you can expect from them.
