'''ResidualVM''' (formerly '''Residual''') was a [[cross-platform]] [[computer program]] comprising [[3D computer graphics|3D]] [[game engine recreation]]s with a common [[graphical user interface]]. It supports ''[[Grim Fandango]]'', ''[[Myst III: Exile]]'', and ''[[The Longest Journey]]''. It merged with ScummVM in October 2020.<ref>{{cite web|title=A merger|url=https://www.scummvm.org/news/20201009/|publisher=ScummVM}}</ref>

ResidualVM was originally designed to play [[LucasArts adventure games]] that use the [[GrimE]] [[game engine]], and was later adapted to support other ones.<ref>{{cite web |title=What If: Grim Fandango Deluxe |website=Rock, Paper, Shotgun |date=13 January 2012 |url=http://www.rockpapershotgun.com/2012/01/13/what-if-grim-fandango-deluxe/ |publisher=[[Rock, Paper, Shotgun]] |accessdate=2012-01-13|last1=Meer |first1=Alec}}</ref><ref>{{cite web |title=Residual extended functionality |url=http://www.residualvm.org/news/20090526/ |publisher=ResidualVM |accessdate=2012-01-29 |archive-date=2015-06-23 |archive-url=https://web.archive.org/web/20150623125303/http://www.residualvm.org/news/20090526/ |url-status=dead}}</ref> Like ScummVM, the ''VM'' in ResidualVM stood for [[virtual machine]].<ref>{{cite web |title=Maniac Tentacle Mindbenders: How ScummVM's unpaid coders kept adventure gaming alive |date=17 January 2012 |url=https://arstechnica.com/gaming/news/2012/01/maniac-tentacle-mindbenders-of-atlantis-how-scummvm-kept-adventure-gaming-alive.ars |publisher=[[Ars Technica]] |accessdate=2012-01-19}}</ref>

ResidualVM is a reimplementation of the part of the [[software]] used to [[interpreter (computing)|interpret]] the [[scripting language]]s by conducting reverse engineering on the original game rather than emulating the [[computer hardware|hardware]] on which the games ran. As such, ResidualVM allows the games it supports to be played on [[system platform|platforms]] other than those for which they were originally released.

The name of the project comes from the fact that it was originally started to support the residual LucasArts adventure games not supported by ScummVM. The original [[Lua (programming language)|Lua]]-based engine used by LucasArts in their 3D adventure games was called GrimE (as opposed to [[SCUMM]]), so ResidualVM's title is also a word pun as grime is a type of residue.

The project was started by former ScummVM team leader James Brown, and was first publicly available on August 15, 2003.<ref>{{cite web |title=ResidualVM Stable Release Supports Grim Fandango |url=http://mixnmojo.com/news/ResidualVM-Stable-Release-Supports-Grim-Fandango |publisher=[[The International House of Mojo]] |accessdate=2013-01-04 |date=2012-12-23}}</ref> Progress on the project was initially slow, and as a result the project's main goal of supporting ''[[Grim Fandango]]'' did not occur until April 25, 2011, when the compatibility of ''Grim Fandango'' was upgraded to "completable with a few minor glitches".<ref>{{cite web |title=Sorry for the wait Mr.Flores! |url=http://www.residualvm.org/news/20110425/ |publisher=ResidualVM |accessdate=2012-01-29 |archive-date=2013-02-05 |archive-url=https://web.archive.org/web/20130205201936/http://residualvm.org/news/20110425/ |url-status=dead}}</ref>

The project obtained a domain separate from ScummVM in December 2011. As a result of the new domain name, the project name was changed from Residual to ResidualVM. The logo was changed to reflect the new name in January 2012. The first stable release of ResidualVM was released 9 years after the project started, on December 21 the same year.<ref>{{cite web |url=http://www.escapistmagazine.com/news/view/121253-Residual-VM-Stable-Release-Brings-Grim-Fandango-to-Modern-PCs |title=ResidualVM Stable Release Brings Grim Fandango to Modern PCs |publisher=[[The Escapist (magazine)|The Escapist]] |date=2012-12-21 |accessdate=2012-12-22 |archive-date=2014-11-02 |archive-url=https://web.archive.org/web/20141102180148/http://www.escapistmagazine.com/news/view/121253-Residual-VM-Stable-Release-Brings-Grim-Fandango-to-Modern-PCs |url-status=dead}}</ref> It merged with ScummVM in October 2021.<ref name="merged"/>

====Support====
ResidualVM was officially available on multiple platforms including [[Microsoft Windows|Windows]], [[Linux]], [[OS X|Mac OS X]], [[AmigaOS 4]], and [[IRIX]].<ref>{{cite web |title=ResidualVM 0.2.1 Bugfix Release |url=http://mixnmojo.com/news/ResidualVM-021-Bugfix-Release |publisher=[[The International House of Mojo]] |accessdate=2014-02-25 |date=2014-02-25}}</ref> In addition, an [[Android (operating system)|Android]] port is available in the source code, and unofficial builds have been made with that source. There is also a port available for the [[Pandora (console)|Pandora]] console, and for [[FreeBSD]], but they are not official as they have not been added to the main branch.

With increased attention, ResidualVM entered into favorable agreements with adventure game developers to help bring their titles into the engine. [[Cyan Worlds]] partnered with ResidualVM to release ''Myst III: Exile'' on digital platforms.<ref name="cyan">{{cite web |url=https://mixnmojo.com/news/Cyan-Partners-With-ScummVM|title=Cyan Partners With ScummVM|publisher=[[The International House of Mojo]]|accessdate=2018-06-23}}</ref>

The digital storefront [[GOG.com]] which specialized in selling digital copies of older games, sells ''Myst III: Exile'' with the ''ResidualVM'' engine as part of its distribution.<ref name="cyan"/>

====ResidualVM supported games====
The stable release supports ''[[Grim Fandango]]''<ref>{{cite web |title=Residual! |url=http://mixnmojo.com/news/Residual |publisher=[[The International House of Mojo]] |accessdate=2012-01-09}}</ref> and ''[[Myst III: Exile]]'', which are completable with a few minor glitches.

In the development branch, there is also support for ''[[Escape from Monkey Island]]'', which is completable with a few glitches,<ref name="Mojo tidbits">{{cite web |title=Return of the Mojo Tidbits |url=http://mixnmojo.com/news/The-Return-of-the-Mojo-Tidbits |publisher=[[The International House of Mojo]] |accessdate=2012-11-13}}</ref> and [[The Longest Journey]], which is completable with missing features.<ref>{{cite web |title=It's GSoC Season For ScummVM and ResidualVM |url=https://mixnmojo.com/news/Its-GSoC-Season-For-ScummVM-and-ResidualVM |publisher=[[The International House of Mojo]] |accessdate=2018-06-23}}</ref>

Like ScummVM, ResidualVM contains fixes for bugs present in the original executable. The ResidualVM team discovered a workaround for a bug that causes a critical dialog not to play in ''Grim Fandango''.<ref>{{cite web |title=Basic Braining: Tim Schafer talks story, the 80s movies behind Psychonauts, and learning to platform |url=http://www.penny-arcade.com/report/editorial-article/tim-schafer-discusses-the-stories-and-inspirations-behind-psychonauts |publisher=[[Penny Arcade (webcomic)|Penny Arcade Report]] |accessdate=2012-03-22 |archiveurl=https://web.archive.org/web/20120622101244/http://penny-arcade.com/report/editorial-article/tim-schafer-discusses-the-stories-and-inspirations-behind-psychonauts |archivedate=2012-06-22}}</ref><ref>{{cite web | url=http://mixnmojo.com/news/Grim-Fandango-Long-lost-bug-found-fixed | title=Grim Fandango Bug Found, Fixed! | publisher=[[The International House of Mojo]] | accessdate=2012-01-24}}</ref> In addition, the ''Grim Fandango'' engine in ResidualVM has fixes for over a dozen other bugs present in the original.<ref>{{cite web | url=http://mixnmojo.com/news/Get-Some-Lumbago-Lemonade-With-ResidualVM-011 | title=Get Some Lumbago Lemonade With ResidualVM 0.1.1 | publisher=[[The International House of Mojo]] | accessdate=2013-01-12}}</ref> There is also a branch of ResidualVM called Grim Mouse, which allows ''Grim Fandango'' to be played completely with a mouse as a traditional point and click adventure game.<ref>{{cite magazine | url=http://www.pcgamer.com/2014/03/02/mod-of-the-week-mouse-interface-for-grim-fandango/ | title=Mod of the Week: Mouse Interface, for Grim Fandango | magazine=[[PC Gamer]] | accessdate=2014-06-08 | date=2014-03-02}}</ref><ref>{{cite magazine |url=https://www.wired.co.uk/news/archive/2014-03/05/grim-fandango-point-click |title=Fan mods Grim Fandango into point-and-click adventure |magazine=[[Wired (magazine)|Wired]] |date=2014-03-05 |accessdate=2014-06-08 |archive-date=2014-07-14 |archive-url=https://web.archive.org/web/20140714213437/http://www.wired.co.uk/news/archive/2014-03/05/grim-fandango-point-click |url-status=dead}}</ref><ref>{{cite web |url=http://www.rockpapershotgun.com/2014/02/25/mod-removes-grim-fandango-tank-controls-world-cheers/ |publisher=[[Rock, Paper, Shotgun]] |date=2014-02-25 |accessdate=2014-06-08 |title=Mod Removes Grim Fandango Tank Controls, World Cheers}}</ref><ref>{{cite web |url=http://kotaku.com/hooray-someone-finally-fixed-grim-fandango-1529330636 |title=Hooray, Someone Finally Fixed Grim Fandango |publisher=[[Kotaku]] |date=2014-02-23 |accessdate=2014-06-08}}</ref>
