This page contains information of emulation history.
Emulation, in general, gained popularity around 1995-1997, mostly due to increased CPU speed, increased usage of the Internet, and increased number of decent emulators.
==History==
*'''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">[http://www.zophar.net/forums/showpost.php?p=85512&postcount=1 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 on 1995.
*'''LandyNES''' by Alex Krasivsky, which seems became the base of iNES emulator. At least one beta version for MS-[[DOSemulators|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> Unfortunately no copy of this emulator remains on the internet; it was mainly hosted on now-defunct FTP sites and none of websites that supposedly hosted it was 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) emulator 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.
Not much is known about GB emulation before 1995.
*[http://fms.komkon.org/VGB/ Virtual GameBoy] (VGB) was first known GB 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]]GMB was released for [[DOS emulators|DOS]] in 1997. GameBoy 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 [[DOS Version emulators|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.
*[http://www.zophar.net/snes/vsmc.html VSMC] was released in 1994 and could run 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/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 MacintoshmacOS. Windows version was released later and allegedly had better compatibility than Bleem!, albeit without enhanced graphics.
===Nintendo 64===
===Game Boy Advance===
Unlike other consoles, GBA emulation and 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 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, 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]]GBA, and [[VisualBoy Advance]].
===GameCube===
===Nintendo DS===
Initial attempt to emulate Nintendo DS was made in 2004. With so many emulators like iDeaS and the leaked EnSata[[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 Nintendo DS, although it only emulated GBA hardware.
* [[Ensata]]: An NDS emulator made by Nintendo (and Intelligent Systems?) that was leaked to emulation community in an unknown year<!-- 2005? 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. The source code was then released. Many devs tried on their own to make their own follow-up (one such emulator includes NDesMumeNDeSmuME, 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 DesmumeDeSmuME.
* [[No$|NONo$GBA]]GBA: originally a GBA emulator, it received e-Reader and NDS 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 DS/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.
===Wii U===
* [[decafDecaf]] was the first released Wii U emulator. Its first commit was on May 18, 2015.<ref>[https://github.com/decaf-emu/decaf-emu/commit/b121b9290c1eca5de0a2f43b5497c2ac6613c397 decaf's initial Github commit.]</ref> However, it didn't run any games until Oct 28, 2015,<ref>[https://www.reddit.com/r/emulation/comments/3qmcnm/decafemu_runs_a_game_now/ Decafdecaf-emu runs a game now! reddit thread.]</ref> a couple weeks after Cemu had released.
* [[Cemu]] was first released Oct 13, 2015.<ref>[http://cemu.info/changelog.html Cemu changelog]</ref> It was the first Wii U emulator that could run games.

* [[yuzu]], a fork of [[Citra]], started research and early development sometime in Spring 2017,<ref name="yuzu announcement">[https://gbatemp.net/threads/yuzu-nintendo-switch-emulator.494181/ yuzu announcement and public release.]</ref> with its first commit on September 24, 2017.<ref>[https://github.com/yuzu-emu/yuzu/commit/6bafd3f4f754e093fe0f99ebf2e1136d3398981a yuzu's NSO support commit on Github]</ref> It was publicly released January 13, 2018.<ref name="yuzu announcement"></ref>
* [https://github.com/gdkchan/Ryujinx [Ryujinx]] was the first Nintendo Switch emulator to boot a commercial game, Puyo Puyo Tetris, when it released on February 4, 2018.<ref>[https://github.com/gdkchan/Ryujinx/tree/b7e1d9930db6d80fcb1f7c5c6b0aa627e42e6595 Ryujinx's initial GitHub commit.]</ref>
