The '''[[wikipedia:X1(computer)|X1]]''' <small>(<span lang="ja">エックスワン</span> ''Ekkusu Wan'')</small> is a Japan-only line of home computers created by [[wikipedia:Sharp_Corporation|Sharp]]’s television division. The first model, simply named Sharp X1, was released in November 1982. These computers doubled as TV sets and included many functionalities that made use of this combination, such as the ability to superimpose text to the TV image and, in later models, even to digitally record live television, albeit in a compressed 8-colour video format. Despite being powerful for its time, the [[NEC PC-8800 series]] outsold it. The last additions to the X1 line, the X1 Twin, also included a built-in [[PC Engine (TurboGrafx-16) emulators|NEC PC Engine]].

:A very recent emulator that progressed very fast. It was the first emulator to support the X1 Twin, and is currently the best one at it. It is the only emulator to receive frequent updates up to this day, and also the only one (besides MAME) to have documentation in English. The X1 Twin core used to have an official Windows CE port, which was discontinued in early 2010. Despite referencing X millennium T-tune code, it does not seem to be a fork. The PC Engine section of its X1 Twin core is based off [[Ootake]].

:Inherited X1 support from [[MESS]]. Its X1 Turbo Z and X1 Twin cores are listed as not working as of November 2019. Despite this, the X1 Turbo core is quite decent.

:One of the numerous forks of X millennium 0.26 t-tune step 1.43, Xmilx’s main selling points are Direct3D support, better window scaling capabilities and added compatibility with [[Kega Fusion]] RPI screen filters. UnfortunatelyAs of version 3, it shares the same timing issues as T-tuneseem to be resolved, making it at the very least a decent emulator.

:Born in the late 1990s as X1R, a real-time mode fork of X1EMU, X millennium was the first Sharp X1 emulator for Windows, and unarguably the most influential to date. It was updated until version 0.26d’s release in 2005, when development halted for no apparent reason. Suddenly, in December 2015, a little over ten years of silence, version 0.60a was released, bringing emulation enhancements ported over from [[NEC PC-9800 series|Neko Project II ]] among other small compatibility improvements. The gap between the last two releases was so wide, however, that version 0.60a all but flew under the radar, impacting the existing forks by little to nothing. In early 2019, the developer’s domain name expired and was not renewed, making a new release highly unlikely − at least before 2025, that is.

:The mother of all Sharp X1 emulators. First released in January 1999 and last updated in July 1999, X1EMU is designed to be compatible both with [[Intel CPUs|IBM -PCs ]] and [[NEC PC-9800 series|PC-98s ]] running MS-DOS. The emulator runs in DOS protected mode, as such, it needs a copy of DOS4GW.EXE to sit in the same folder as it. Unlike most of its offspring, it is entirely in Japanese. In late-1990s machines, it might not exhibit this issue, yet in modern computers, its emulation is ridiculously fast, as there seems to be no programmed limitation on the clock speed.

:Probably the first truly functional Sharp X1 emulator to ever be coded, and the first to be open-source. It was first released through a BBS in '''1993''', when the Sharp X68000 was still on shelves all around Japan. ApparentlyIn the readme, it is only capable of emulating the original X1coder mentions an earlier payware he used as a reference simply named “X1 Emulator”, which means high-res mode applications won’t workwas barely usable and doesn’t seem to be archived online. It X1 Emulator for X68000 is only able to run at a maximum of 31 kHZ, and is also incompatible with the D88 image format, accepting only 2D files. It is hideously outdated and pretty much useless nowadays for anyone who doesn’t own a Sharp X68000, yet it is an important footnote on Sharp X1 emulation history. After its initial release, it was picked up by another developer and received small updates until 1999 (!). Curiously, it has some functions that other emulators wouldn’t pick up on until over one decade later, such as having four emulated floppy drives, the option to change clock speed and not requiring ROM dumps to work. Its configurations are stored in the CONFIG.X1 file; for usage help, use the -? switch on the command line.
