In addition to the CPC, it also emulates the [[Acorn Electron]], [[Atari 2600]], [[Commodore Vic-20]], [[MSX|MSX 1]], [[Oric 1/Atmos]] and the [[Sinclair ZX80/81]], and seeks to offer all as complete turnkey systems: just open a media image and it'll figure out the target machine, that machine's proper configuration and any commands necessary to launch the media, then it will launch the software contained on the media. The emulator's job is to be as inconspicuous as possible, allowing the user simply to enjoy the work of classic-era authors with no prior knowledge of the emulated machine in use.
It therefore seeks to be the antithesis of the heavily-chromed ostentatious emulators: it seeks to be an invisible link in the user's use of a piece of software.
