Editing History of emulation

This page contains information of console emulation history.

Emulation, in general, gained popularity around 1995-1997, [[PC_Emulator_Comparisons#x86_CPU.27s|mostly due to increases in CPU speed]], the increased usage of the Internet, and the increased number of decent emulators.

==History==
 
===Arcade===
Before MAME back in 1997, there was multiple standalone arcade games emulators, only capable to emulate a single game. Games like Rygar, Gauntlet, Ghosts'n Goblins, Bombjack, Asteroids, Mr. Do! Series, Pac-Man, Lady Bug, all of them came in your own custom emulator. This was around 1994-1995. 

Later, Sparcade by David Spicer <ref>[https://web.archive.org/web/20010202172300/http://www.sparcade.freeserve.co.uk/download.htm Sparcade 2.25 and 2.33b Download] (1998 and 1999 releases)</ref> was capable of running some arcade games in 1996<ref>[https://www.myabandonware.com/game/sparcade-47o Sparcade!] (1.94 release 1996)</ref>. 

1998 was also the year of the release of various complex multiple arcade games emulators, such as [[Callus]]<ref>[https://web.archive.org/web/20080701073241/http://bloodlust.zophar.net/Callus/callus.html Callus 0.42 download page]</ref>(Capcom CPS-1) and System16<ref>[https://system16.com/emu-sys16.php System16 Download page]</ref> (Sega System 16)<ref>[https://web.archive.org/web/19990119235522/http://abyssweb.ml.org:80/s16w32.html original System16 page]</ref>. 

===Commodore 64===
The first Commodore 64 emulator appeared on BBSs in early 1990s. C64S is capable of running games on a 286 IBM PC. <ref>[https://commodore.software/downloads/download/193-c64s/11782-c64s-v0-9a C64S v0.9a Download]</ref>

===Atari 2600===
Activision released the “Atari 2600 Action Pack” for Windows 3.1 on June 1995. It was the first Atari emulator known. Later emulators appeared in 1996, “VCS2600” and “Stella”. <ref>

===NES===
The early history of NES emulation is vague, but there are some early emulators known to the public.

*'''Family Computer Emulator V0.35''' for FM Towns, by "Haruhisa Udagawa", with file timestamps of December 12, 1990. It could run some simple NES games such as Donkey Kong.<ref name="Zophar NES post">[https://www.zophar.net/forums/index.php?threads/first-famicom-nes-emulator.10169/ MyaMyaMya's post in "First Famicom/NES emulator?"]</ref>
*'''Pasofami''' for the FM Towns, with a release date of May 1, 1993, in its info file. It had very preliminary sound emulation.<ref name="Zophar NES post"></ref> Windows version was released in 1995.
*'''LandyNES''' by Alex Krasivsky, which it seems became the base of iNES emulator. At least one beta version for [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#Intel_CPU.27s|DOS]], called '''Prerelease "Stupid" version''', was released to the public on September 8, 1996 with the filename "DC-NES.ZIP".<ref>[http://lngn.net/archaic-ruins/features/ar-dc/nes-emu.htm#lnes Archaic Ruins: Nintendo]</ref> This version supported some simple Mapper 1 games and had graphical glitches.<ref>[http://oldies.malban.de/firstpage/EMU2.HTM EMULATOR PAGE 2]</ref> Luckily on January 5, 2023, the emulator was discovered on the internet archive<ref name="LandyNES on Lost Media Wiki" >[https://lostmediawiki.com/LandyNES_(found_early_NES_emulator_software;_1996)#Discovery LandyNES on Lost Media Wiki]</ref>; it was mainly hosted on now-defunct FTP sites and none of the websites that supposedly hosted it were archived by Wayback Machine. This project was discontinued after the release of NESticle.
*Marat Fayzullin's [http://fms.komkon.org/iNES/ iNES] (also known as interNES in early versions) is the first (or at least one of the first) emulators to use [http://wiki.nesdev.com/w/index.php/INES NES header format (also known as iNES format)]. The release date of the first version is 1996 according to its site.
*[http://www.zophar.net/documents/nes/nesa.html NESA] (Nintendo Entertainment System in Assembler) by British programmer Paul Robson was one of the first free NES emulators with source code available. [http://metopal.com/2012/04/06/interview-paul-robson-programmer-of-the-nesa-emulator/ metropal.com] has an interview with the author.
*[[NESticle]] (first version known as v0.2) was released on April 3, 1997. It was one of the first freeware NES emulators.
*There was an unreleased NES emulator for the Genesis that was programmed by Yuji Naka during the early 1990s as a hobby.

===Game Boy/Color===
Not much is known about GB/C emulation before 1995.
*Marat Fayzullin's [http://fms.komkon.org/VGB/ Virtual GameBoy] (VGB) was first known GB/C emulator that could run commercial games. First released in 1995 for some unknown platform then ported to PC sometime in 1995 or 1996.
*[[No$|No$GMB]] was released for [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#Intel_CPU.27s|DOS]] in 1997. Game Boy Color support was added in 1998 along with it being paid only.

===Genesis===
Genesis emulation dates as early as 1994.
*An emulator simply called [http://segaretro.org/Megadrive_(emulator) Megadrive] released in 1994 could run Sonic the Hedgehog very slowly with no sound and many glitches. Quickly discontinued because the author lost its source code from a hard drive crash. It is currently the earliest known Genesis emulator.
*[http://segaretro.org/GenEm GenEm], first released in 1996, is the second Genesis emulator released. The [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#Intel_CPU.27s|DOS]] version of it was the first emulator to feature (preliminary) sound emulation.
*[[Genecyst]], first released in 1997 was one of the first widely used Genesis emulators.
*[http://www.zophar.net/genesis/kgen.html KGen] was the earliest predecessor of [[Kega Fusion]], released around 1997-1998.

===SNES===
Just like the NES, the SNES emulation history is quite fuzzy, but there is evidence that SNES emulators existed as early as 1994.

*[http://www.zophar.net/snes/vsmc.html VSMC] was released in 1994 and could run a select few Homebrew roms. Apparently it was updated a few times after its initial release, and later versions could run some commercial games including Final Fantasy 2.<ref>[http://ftp.lanet.lv/ftp/mirror/x2ftp/msdos/programming/reviews/emu_002.txt EMULATION Issue #2 - 23/07/96]</ref> [https://www.youtube.com/watch?v=J7YXaaYdPGw (Video of one early version. Please note the music is inserted by video editing, not from the emulator.)]
*'''Super Pasofami''' or '''SPW''' (Super Pasofami for Windows), developed by the author of Pasofami, was released sometime in 1996. Very little information is available about this emulator aside of the reports that version 1.4a deleted some people's Windows directories.<ref>[http://ftp.lanet.lv/ftp/mirror/x2ftp/msdos/programming/reviews/emu_004.txt EMULATION Issue #4 - 28/08/96]</ref>
*[http://www.zophar.net/snes/esnes.html ESNES] was one of the first SNES emulators that could emulate sound. It later merged with NLKSNES to become NLKE.
*[http://www.zophar.net/snes/nlksnes.html NLKSNES] was one of the fastest SNES emulators, though it lacked sound emulation. It later merged with ESNES to become NLKE.
*[http://www.zophar.net/snes/nlke.html NLKE] is a successor of ESNES and NLKSNES and contained both speed and sound.
*[[Snes9x]] was a merged effort of '''Snes96''' and '''Snes97''', both released sometime in 1996-1997.
*[[ZSNES]] was first released on October 14, 1997.

===PlayStation===
The earliest known attempt at PlayStation emulation was in 1998. PlayStation emulation is notable for two controversial commercial emulators, both of which Sony tried to sue, and lost.
*[http://www.zophar.net/psx/psemu-psemu-pro.html PSEmu/PSEmu Pro], first released in early 1998, was one of the earliest PS emulators that could run commercial games. It also created the plugin standard that is still used by [[ePSXe]].
*[http://www.zophar.net/psx/psyke.html Psyke], released around 1998-1999, was the first PS emulator that used Dynamic Recompilation to speed up the emulation. It could run a few games such as Metal Slug and Tekken 3. An interview with the author on September 13, 1998, is available on [http://www.emuviews.com/show.php?SERIAL=223 this site].
*[[Bleem!]], first released in March 1999 for Windows, was a commercial software that could run several commercial games in full speed with enhanced resolution and texture filtering. There were also three separate Dreamcast versions that could run Gran Turismo 2, Metal Gear Solid and Tekken 3.
*[https://en.wikipedia.org/wiki/Connectix_Virtual_Game_Station Virtual Game Station], another commercial emulator, was released in 1999 but for Macintosh. Windows version was released later and allegedly had better compatibility than Bleem!, albeit without enhanced graphics.

===Nintendo 64===
Earliest known attempt at N64 emulation is 1998.
*[http://www.zophar.net/n64/project-unreality.html Project Unreality], released in May 1998, was the first Nintendo 64 emulator that could run several homebrew ROMs and could show N64 logo screen of Mortal Kombat Trilogy and Wave Race 64. It was discontinued after the two main developers decided to join a game development company to create commercial N64 games.<ref>[http://games.slashdot.org/story/98/07/12/1713252/project-unreality-in-limbo Project Unreality in limbo (Slashdot)]</ref>
*[[UltraHLE]], released in January 26, 1999, was so good that it angered Nintendo.
*[http://www.zophar.net/n64/Nemu64.html Nemu64], probably released in 2000, was one of the first N64 emulators that used plugin system that is still used by [[Project64]] and was used in early versions of [[Mupen64Plus]]. It is also known for its extensive debug features which none of the newer emulators have.

===Game Boy Advance===
Unlike other consoles, GBA emulation and the Homebrew scene was started as early as 2000, a year before GBA's release. <!-- Why? I don't know... I heard a rumor that some GBA internal docs have leaked (as well as Yoshi demo) but I have no source. -->
*[http://www.zophar.net/gba/gbaemu.html GBAEmu], released in September 2000, was the first known GBA emulator. It could run some homebrew ROMs as well as Nintendo's "Yoshi's Story" tech demo.
*[http://fms.komkon.org/VGBA/ Virtual GameBoy Advance (VGBA)], done by the same author of iNES and VGB - Marat Fayzullin, was first released in 2000 according to its official site. In versions released in 2001, it could run a few commercial games.
*[http://www.zophar.net/gba/igba.html iGBA], which was available as early as February 2001 and last updated on March 25, 2001, could run a few commercial games with some graphical glitches and with no sound.
*Several GBA emulators with more accuracy were released in 2001, for example [http://www.zophar.net/gba/boycott-advance.html Boycott Advance], [http://www.zophar.net/gba/dreamgba-tng.html DreamGBA], [[No$|No$GBA]], and [[VisualBoy Advance]].
*[[mGBA]], originally intended to be written in JavaScript, began development in 2013 with its first release in early 2015.  It aimed for accuracy on low-end machines and has since been one of the best GBA emulators around.

===GameCube===
* [[Dolphin]] was first released on Jan 24, 2004. More info: [https://www.youtube.com/watch?v=WdhoFIRHckE 10 Years of Dolphin video.]

* [https://code.google.com/archive/p/gekko-gc-emu/ Gekko] was started in April 2006.

===Xbox===
Xbox emulation dates as far back as 2002.
* [[Cxbx]] was released as a proof of concept in August 2002. It can do some test apps and later commercial games. Discontinued in October 2015.
* Xeon, released in 2003, was the first Xbox emulator whose first version could play games, but the only game that it could boot and show graphics was Halo CE.
* Dxbx is a fork of Cxbx, released in 2008.
* [[Cxbx-Reloaded]] is a fork of Cxbx that went open-source in April 2016. Because little work has been done on the original CXBX, its development is very slow (equals 15% playable titles), and like older Xbox emulators, it didn't need a BIOS dump to work.
* [[XQEMU]] was the first low-level Xbox emulator. Its first commit was on February 1, 2009. It emulated games at slow speeds. Its last commit was in December 2019.
* [[xemu]] is a continuation of XQEMU, released somewhere in February 2020. It can play 5x more titles than Cxbx-Reloaded and requires a BIOS dump to work.

===Nintendo DS===
The initial attempt to emulate the Nintendo DS was made in 2004. With so many emulators like iDeaS and the leaked [[Ensata]], it only got decent enough by 2007.

* [http://www.zophar.net/ds/dsemu.html DSEmu], first released in 2004, was the first "attempt" to emulate the Nintendo DS, although it only emulated GBA hardware.

* [http://www.zophar.net/ds/ideas.html iDeaS], first released in 2004 or 2005, was the first Nintendo DS emulator that could run commercial games. It also had some plugin system that was not widely used.
<!-- http://www.ne.jp/asahi/krk/kct/misc/emu.htm says 2004 for above two emulators but no other source mention release dates -->

* [[Ensata]]: An official Nintendo DS emulator made by Nintendo (and Intelligent Systems?) that was leaked to emulation community in an unknown year (perhaps 2005 or 2006). It could run select few commercial games, though compatibility was very low.

* [[DeSmuME]]: Developed by YopYop156 around 2005, first as "YopYop DS". Discontinued at version 0.3.3 in April 2006, citing a change of laws regarding emulation in France (although it was just an April Fools joke).<ref>[http://wiki.desmume.org/index.php?title=Faq#What_are_the_origins_of_DeSmuME.3F DeSmuME FAQ - What are the origins of DeSmuME?]</ref> The source code was then released. Many devs tried on their own to make their own follow-up (one such emulator includes NDeSmuME, of which only one version was ever released), before teaming up and merging their work, resulting in build 0.5.0 as the starting point for the new emulator.

:With partial Wi-Fi emulation enabling online MP (but not local MP) in 2010, Nintendo supposedly threatened the devs with legal action (though this is unconfirmed). This resulted in the online Wi-Fi functionality being removed from the main trunk, yet it still had its own active branch which didn't face any legal action whatsoever.

:The main trunk devs decided to drop all development of the Wi-Fi feature or anything related (online, local, download play, Wii/DS connectivity, DSiWare). This had the unfortunate side-effect of stalling efforts to preserve online content near the closure of Nintendo's DS servers in 2014 as other parties were scrambling to get the emulation enough to preserve packets from online play.

:Similarly, the high-resolution DS rendering feature appeared first in shikaver's port (X432R), which was also more optimized for speed and kept getting updated with features from the trunk. Then in the closed-source commercial emulator [[DraStic‎]], before making it to DeSmuME.

* [[No$|No$GBA]]: originally a GBA emulator, it received e-Reader and Nintendo DS emulation by its 2.4 version by 2006. It was for a long time THE emulator for DS games. It also had a partial implementation for local multiplayer that went nowhere and a very useful debugger for modding NDS/GBA games. Development stalled for a long time with version 2.6a published in April 2008. While it's not nearly up-to-par with the more recent games due to graphical problems, the apparent crashes on boot could be solved with a separate tool to decrypt DS images.

:Came back after a long hiatus in 2014 with version 2.7 and is now more or less under development - 2.8a notably is the first emulator to include DSiWare emulation.

*[[melonDS]]: Started development in early 2017 by a former DeSmuME contributor, its main claim to fame has been its attempt at implementing Wi-fi capabilities that others lack and to bring back interest to a stale emulation scene which started to see a renewed interest with new emulators beginning development such as [https://corgids.wordpress.com/ CorgiDS], [[mGBA#medusa|medusa]], and [[GBE+]], around the same time.

===PlayStation Portable===
*PSP Player was the first PSP emulator, starting development on July 4, 2006.<ref>[https://github.com/benvanik/pspplayer/commit/1765423c9565a7435da2df0adc5e0bc662dcb364 PSP Player's initial commit.]</ref> It was the first PSP emulator to boot and run a game on Mar 6, 2008.<ref>[https://www.youtube.com/watch?v=zqyIjPFHKsI PSP Player emulating Puzzle Bobble on YouTube]</ref>
