Changes

Sometimes a full system emulator is overkill. This is especially true when a developer only wants to get one game (or a number of games that use the same engine) working. In that case, reimplementing that game alone would save more time than implementing the platform it runs on. These kinds of projects are common when abandonware has large communities; when the original developer has disbanded and can no longer support or update it, an effort is then made to get it running natively on newer versions of-- and/or entirely different-- operating systems and platforms.

* In rare cases, games are released as open-source by the publishers themselves, allowing developers to perform a '''source port''' of the code. This skips the step of figuring out how the game works. The most common example that's often used is id Software's release of Doom in 1997. It led to [[wikipedia:List of Doom source ports|so many ports being released]] that the community began to joke about what devices haven't gotten it running yet.

For the sake of brevity, most of these projects often refer to themselves under some variety of '''fan remakes'''. The [[#External links|External links]] section has lists for a number of known and available projects.

On Linux downloading and using game engines is easy with [https://github.com/luxtorpeda-dev/luxtorpeda Luxtorpeda] - a Steam Play compatibility tool (like [[Proton]]) that allows you to run games from Steam using various different game engines and reimplementations.
