At the time, Sharp was following a ''Clean Computer'' philosophy: this means that, in order to leave the user in control of the RAM, the computer shipped only with an IPL and BIOS. When necessary, operating systems must be loaded using external storage devices, such as cassettes and, in all but the first model, floppy disks.

===Comparisons===

;eX1

;[[MAME]]

: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.

;WinX1

:An independent emulator, born in 1999 and defunct in 2000. Differently from most other emulators, it is entirely in Japanese. Despite apparently not being a fork of anything, the author did refer to the source codes of X1EMU, X1R/X millennium and MAME. Rumours around the existence of versions 0.09 and 0.10 do float, as WinX1 ~ikafumi~ is said to be based off WinX1 0.10, yet those seem to be vaporware.

;X1 Emulator for X68000

: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. In the readme, the original coder mentions an earlier payware he used as a reference simply named “X1 Emulator”, which was barely usable and doesn’t seem to be archived online. X1 Emulator for X68000 is only able to run at a maximum of 31 kHZ, and is 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 It is hideously outdated and pretty much useless nowadays for anyone who doesn’t own a Sharp X68000, yet it is an important footnote on Sharp X1 emulation history.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.
