Game engine recreations and source ports

From Emulation General Wiki
Jump to navigation Jump to search

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.

  • When the developer only has a binary to work with (and not the source code), they recreate the engine rather than port it, hence the term game engine recreations (or alternatively game engine re-implementations). How the developers go about this process depends on their philosophy; they may opt to decompile the original executable and have their own program rely on the original until all of its functions have been remade, at which point the original binary is no longer needed. Alternatively, they can be remade based on a clean room design, in which the project implements the abstract features without having to disassemble the original, going by how components are expected to be used rather than how the game uses them. Some engines come about simply because they were inspired by the original game, and the programmer felt confident enough that no reverse engineering was necessary to make an engine that does the same thing.
  • 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 so many ports being released that the community began to joke about what devices haven't gotten it running yet.

Some projects are implemented in ways that the original developer did not intend; for example, for a platform other than which publishers marketed it for. And they're not just limited to game engines either; Webamp is a JavaScript application that reimplements Winamp in the web browser. These projects are almost always open-source which also allows new programmers to fix bugs that could have been difficult to track down during development (alternatively, the bugs may be emulated to allow old mods to continue to safely exploit them). When most of the effort is on programming, the project will usually require the original game's assets (such as files in the installation directory or ROMs) until those ever get remade. This lets the developers claim they aren't infringing the game's copyrights since the player must obtain the original to use it; if the game is still being sold, this could allow the publisher to even earn revenue from the project.

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

On Linux downloading and using game engines is easy with Luxtorpeda - a Steam Play compatibility tool (like Proton) that allows you to run games from Steam using various different game engines and reimplementations.

Notes[edit]

  1. OpenLara was inspired by OpenTomb
  2. VoidSW is included with EDuke32
  3. ZDoom has been discontinued. However the development of its replacements, GZDoom and LZDoom, is still active.
  4. Stratagus is an open-source real-time strategy game engine. Some standalone games like Aleona's Tale (included in Wargus's installation), Astroseries, Bos Wars, and Wyrmsun were built on the Stratagus game engine. Source ports for Warcraft: Orcs & Humans (War1gus), Warcraft II: Tides of Darkness + Beyond the Dark Portal (Wargus), and StarCraft (Stargus) were also built on the Stratagus engine.
  5. Stargus is in pre-alpha but development has been halted. Stratagus, Wargus, and War1gus are being updated regularly.
  6. StarCraft is only partially playable in Stargus as of v2.4.1. Warcraft games for Wargus & War1gus work well if installed correctly.
  7. Ship of Harkinian requires either the GameCube's PAL Debug version (recommended) or the regular PAL GameCube version (not recommended) of The Legend of Zelda: Ocarina of Time to generate an oot.otr file to play it.
  8. The project de-compiled the game into GOAL code. The project also developed a general-purpose GOAL compiler. Ports of Jak 2 & 3 may be viable because they were made in GOAL too.
  9. 9.0 9.1 9.2 DXX-Retro, also known as DXX-Rebirth-Retro, requires files from DXX-Rebirth version 0.58.1 to be able to use. DXX-Switch is a port of DXX-Retro for Nintendo Switch and DXX-3DS is a Nintendo 3DS port of DXX-Switch, but they have technical issues that make them less playable.
  10. 10.0 10.1 HHeretic is an open source game engine of Heretic for Linux. Heretic Wii is a Wii port is based on HHeretic 0.2.
  11. 11.0 11.1 11.2 HHexen, also known as Hacked Hexen, is a Hexen source port was created by Dan Olson and maintained by the Hammer of Thyrion (Hexen II). It is a more advanced and portable version of the Linux Hexen source port and effectively replaced it. Hexen Wii and HHexen (Wii) are both Wii ports of Hexen based on HHexen 1.6.1.
  12. PrBoom-plus is still active
  13. QuakeGX is a Wii port of Peter Mackay's GameCube Quake port. Both are available on the same website. A forked version of QuakeGX called Quake Wii was later merged with QuakeGX.
  14. Quake Rev PAK (or QRevPack for short) is a collection of game engines of the Quake series that merges Q1Rev (Quake 1), [1] (Quake 2), Q2CTFRev (ThreeWave Capture the Flag mod for Quake II), and QWRev (QuakeWorld) in one. All by the same developer Izhido.
  15. vkQuake is based on Quakespasm, but uses Vulkan instead of OpenGL for rendering
  16. 16.0 16.1 16.2 16.3 16.4 Five Nights at Freddy's 1 3DS -remastered- is an updated version of Five Nights at Freddy 1's 3DS by the same developer FreDev, also known as BumboDEV and BaseDEV. The developer also attempted Nintendo 3DS ports of Five Nights at Freddy's 2, 3, and 4 but development stopped after the developer lost the source code for Five Nights at Freddy's 2 and would have to reverse engineer it again.[2] Those ports were only in a state of demonstration and were not fully playable, having incomplete A.I., gameplay, and missing screens. Download links to the latest version of these 3DS ports and the PS Vita port can be found on the old Discord server.
  17. Cave Story Engine 2, or CSE2 for short, received a DMCA cease and desist notice from Nicalis, the current IP owner of Cave Story, despite the original Cave Story being a freeware developed by Daisuke "Pixel" Amaya.
  18. Based on Stunt Car Racer Remake for Windows
  19. 19.0 19.1 19.2 19.3 19.4 19.5 19.6 re3 and reVC have been taken down by Take-Two again. This also includes GaryOderNichts's Wii U ports, Graber's Switch ports, and the PS Vita ports of re3 and reVC.
  20. RE3 3DS is only playable on New Nintendo 3DS/2DS but even then, there will be occasionally graphical issues and frame drops.
  21. DopeWars PC port's download link is currently not working.
  22. DDLC-LOVE is a DDLC! port programmed in Lua. Even in its final release, there may be issues DDLC-LOVE may not have been able to fix but it's still playable. The developer recommends PS Vita users to use Doki-Doki-Literature-Club-Vita for the full DDLC! desktop experience including mod support.
