The '''[[wikipedia:Game & Watch|Game & Watch]]''' is a series of self-contained handheld LCD games by Nintendo where the first one was released on April 28, 1980, and which are often seen as the precursor to the [[Game Boy/Game Boy Color emulators|Game Boy/Color]], although new Game & Watch games were still released as late as 1991. 

Despite their simplicity, Game & Watch handhelds were completely unemulated for a very long time due to a lack of information about their hardware and difficulties with dumping ROMs and accurately recreating graphics. After an [http://forums.bannister.org//ubbthreads.php?ubb=showflat&Number=97003#Post97003 extensive reverse-engineering effort by several MAME developers], MAME became the first emulator to support many retro handheld electronic games, including Game & Watch systems.

;[[MAME]]:
It was officially the 1st Game & Watch emulator, with support for almost all games. It started to comprehensively cover the Game & Watch games from around just before mid-2017 (e.g. [https://wiki.mamedev.org/index.php/MAME_0.185 0.185] in May 2017) and emulated its first game in [https://wiki.mamedev.org/index.php/MAME_0.186 0.186]. <br> Since July 9, 2020, MAME supports at least one version of each Game & Watch model.

;'''DSP''':It was officially the 2nd Game & Watch emulator. Just before mid-June 2017, it also started to emulate a few notable Game & Watch "Thanks to MAME for the ROMs and the info." (as stated in the [https://github.com/leniad/dsp-emulator readme]). 

===Emulation issues===
Although Game & Watch emulation has recently become possible, it took quite a while to achieve due to the [http://www.romhacking.net/forum/index.php?topic=17884.msg259362#msg259362 lack of information] about the microcontrollers driving them and the high difficulty of dumping the ROM from a system. (To dump a game's ROM, the microcontroller often must be decapped, which is not only very costly and complicated but highly destructive to the system.) The lack of information on the Game & Watch's hardware leads to the false belief that it does not contain a CPU or ROM and therefore could not be emulated. Even though this was disproven after reverse engineering efforts of several MAME developers which led to support for all of the games. Emulation of the games had been progressing slowly due to the high amount of time and patience it takes to dump their ROMs and recreate their graphics.

===Graphics===
Even when a Game & Watch game's ROM had been dumped, one of the biggest challenges with accurately emulating it was with how the Game & Watch displayed graphics. Rather than by sending output to an LCD display like most cartridge-based handhelds do, Game & Watch games (as well as most other handheld electronic games from the same time) displayed graphics by lighting up pre-drawn LCD segments, like a calculator. To recreate this as accurately as possible, MAME uses .SVG files traced from high-quality scans of the LCD screen, allowing graphics in supported Game & Watch games to be displayed crisply at any resolution without the loss of any detail. While this is the most accurate way to recreate the LCD graphics outside of obtaining the original art from Nintendo, it is a difficult and time-consuming process as not only does the LCD need to be scanned at a high resolution with all segments lit up to capture all of the graphics but the scans must be traced very carefully to faithfully recreate the original artwork.

=Games=
The main way of playing these games outside buying any of the units second hand is MAME, its accuracy automatically makes it the recommended way of playing these games but if you really don't want to use it, there are other ways in the simulators list.

!Description 
|-
|Nintendo 
| Nintendo officially released virtual reproductions in the games and compiled them in the ''Game & Watch Gallery'' (and, later, ''Game & Watch Collection'') series of games. These games had both "classic" and "modern" variations of these games. While these collections have a loss of "authenticity" (especially in the collections that are running on earlier hardware), these collections are Game Boy, Game Boy Color, Game Boy Advance, and Nintendo DS games for which emulators are widespread. (A few games are from the DSiWare series, though every game in the DSiWare series appears in another collection.) However, some of the games in the collection (notably ''Zelda'') may need to be unlocked before play.

<div style="flex: 1 0 240px;">
* The silver version of Fire has slightly different gameplay than the widescreen version.
* The three Panorama titles listed above are completely different games than the standard versions despite the same names.
* The tabletop version of Mario's Cement Factory is similar to the widescreen and panorama versions but has different artwork and slightly different gameplay.
* From an emulation point of view, the 2009 re-release of Ball is a completely new game with a different CPU and a different program compared to the original Ball release.
