Fuse - the Free Unix Spectrum Emulator

What is it?

Fuse (the Free Unix Spectrum Emulator) was originally, and somewhat unsurprisingly, a ZX Spectrum emulator for Unix. However, it has now also been ported to Mac OS X, which may or may not count as a Unix variant depending on your advocacy position. It has also been ported to Windows, the Wii, AmigaOS and MorphOS, which are definitely not Unix variants.

What features does it have?

Accurate 16K, 48K (including the NTSC variant), 128K, +2, +2A and +3 emulation.
Working +3e, SE, TC2048, TC2068, TS2068, Pentagon 128, Pentagon "512" (Pentagon 128 modified for extra memory), Pentagon 1024 and Scorpion ZS 256 emulation.
Runs at true Speccy speed on any computer you're likely to try it on.
Support for loading from .tzx files, including accelerated loading.
Sound (on Windows and Mac OS X, and on systems supporting ALSA, the Open Sound System, SDL or OpenBSD/Solaris's /dev/audio).
Kempston joystick emulation.
Emulation of the various printers you could attach to the Spectrum.
Support for the RZX input recording file format, including 'competition mode'.
Emulation of the DivIDE, Interface I, +D, Beta 128, Opus Discovery, Kempston mouse, Fuller audio box, Spectrum +3e, ZXATASP and ZXCF interfaces.
Emulation of the Spectranet interface.

What is it lacking?

Quite a lot! However, it's a lot better than it used to be...

Downloads

Unix

Packages are available for some Unix distributions; in general, any problems which are specific to the packages should be sent to the package maintainer.

Official packages of 1.0.0 for Debian, maintained by Alberto Garcia, are available. The packages should also work on Ubuntu.
Fedora has packages of 1.0.0 available.
FreeBSD has a port of 1.0.0.1 available as emulators/fuse.
Nokia's Maemo platform has a port of 1.0.0 available by Alberto Garcia.
NetBSD users can get version 1.0.0.1 from pkgsrc (the NetBSD Packages Collection) as emulators/fuse and emulators/fuse-utils.
The Polish Linux Distribution has packages of Fuse 1.0.0 and the utilities.

Packages of older versions of Fuse are also available for some other distributions:

Gentoo users have an ebuild of 0.10.0.2 available.
Mandriva packages of 0.10.0.2 are available from the Penguin Liberation Front.
OpenBSD users have version 0.10.0.2 available from ports as ports/emulators/fuse, and ports/emulators/fuse-utils/, with thanks to Alexander Yurchenko.
SuSE users have version 0.10.0.2 as the Fuse package.

Mac OS X

A native port to OS X by Fredrick Meunier is available on its own SourceForge project here, as well as a Spotlight importer for Mac OS X 10.4 Tiger users. Alternatively, the original version of Fuse will compile on OS X 10.3 (Panther) or later.

Windows

A port to Windows of 1.0.0.1 by Sergio Baldovi is available here, and the utilities are available here.

AmigaOS 4

Chris Young has ported Fuse 0.10.0 to AmigaOS 4, with binaries available from Aminet as misc/emu/fuse.lha.

MorphOS

Q-Master has ported Fuse 0.10.0.1 to MorphOS, with binaries available from AmiRUS.

PSP

Akop Karapetyan has ported Fuse to the PSP. Binaries and source, based on Fuse 0.10.0.1, are available from the Fuse PSP page.

Wii

A Wii port, based on work by Björn Giesler, is available from WiiBrew. This is based on what is essentially 0.10.0.2.

Gizmondo

A port of 0.9.0 to the Gizmondo tablet is available. The source is available via csie.org.

GP2X

Ben O'Steen has made a GP2X port, based on Fuse 0.6. Binaries and source are available from his homepage.

XBox

Crabfists's has made an Xbox port, based on Fuse 0.6. Binaries and source are available from the FuseX project at SourceForge.

PocketPC

Anders Holmberg's ported Fuse 0.4 to the PocketPC as PocketClive.

Smartphone

Keith Orbell's then ported PocketClive to the Smartphone as FuseSP.

Source

Installing Fuse

First, check the requirements below and ensure all the libraries you want/need are installed.
Secondly, install libspectrum.
Get the source code (PGP signature).
The utilities which were previously packaged with Fuse are now available in their own package (PGP signature). Note that you'll still need libspectrum installed to run these.
The source code releases above are signed with the Fuse Release Key, ID D0767AB9, which has fingerprint 064E 0BA9 688F 2699 3267 B1E5 1043 EEEB D076 7AB9. This is different from the key used to sign the 0.6.0(.1) releases as I forgot the passphrase for that key :-(.

Requirements

Required:

X, SDL, svgalib or framebuffer support. If you have GTK+ installed, you'll get a (much) nicer user interface under X.
libspectrum: the Spectrum emulator file format and information library.

Optional:

libgcrypt: the ability to digitally sign RZX files (note that Fuse requires version 1.1.42 or later).
libpng: the ability to save screenshots.
libxml2: the ability to load and save Fuse's current configuration.
libjsw: allow joystick input to be used (not required for joystick emulation).
zlib: support for compressed RZX files.
libbzip2: support for certain compressed files.
libaudiofile: support for loading from .wav files.
Versions previous to 0.10.0 used John Elliott's lib765 and libdsk for the +3 support. 0.10.0 and newer include this support natively, so these libraries are no longer necessary (or used).

What's new?

1.1.0

Emulation of the Spectranet, SpeccyBoot, SpecDrum and DISCiPLE interfaces
Support for reading PZX and POK files
Support for recording FMF movies
GTK+ 3 compatability

Development

If you're just want news of new versions and the like, the (low volume) fuse-emulator-announce list is available. If you're interested in the development of Fuse, this is coordinated via the fuse-emulator-devel list and the project page on SourceForge.

The latest version of Fuse is always available by checking out the 'trunk/fuse' directory from the Subversion repository on SourceForge. Note that this isn't guaranteed to compile, let alone work properly. Also, don't expect any support for this version! (You'll also need libspectrum from Subversion; this is in the 'trunk/libspectrum' directory). Similarly, the utilities are available in the 'trunk/fuse-utils' directory.

One thing which isn't in the SourceForge tracking system (and is now very outdated):

David Gardner has produced a patch to give XVideo support for the Xlib UI, allowing arbitrary sized windows.

Are there any related projects?

libspectrum is the library used by Fuse to handle various file formats.
Mike Wynne's ZX81 emulator, EightyOne is also using Fuse's Z80 core.
Matthew Westcott's JSSpeccy uses a Z80 core based on translating Fuse's core to Javascript.
Alexander Shabarshin's SPRINT, an emulator of the Peters Plus super-Speccy, the Sprinter. SPRINT is using Fuse's Z80 core for its CPU emulation.
z80ex, a Z80 emulation library based on Fuse's Z80 core, used by zemu and PocketSpeccy.
