Fuse (the Free Unix Spectrum Emulator) is a ZX Spectrum emulator.
It supports several models (including the 128), with faithful emulation of the display and sound.
The emulator can load Z80, SNA and SZX snapshots, as well as TAP and TZX virtual-tape files.
Saving to SZX, Z80 and SNA snapshots and TZX and TAP tape files is supported. The SLT extension to the Z80 format is partly supported (enough for multi-load games); however, loading of the old DAT-file variant is not. DSK disk images are supported when emulating a +3, TRD and SCL disk images are supported when emulating a Pentagon or Scorpion and DCK cartridge images are supported when emulating a Timex 2068 variant. Interface II ROM cartridges are also supported.
Fuse supports various front-ends. The usual one is GTK+-based, but there are also SDL, Xlib, SVGAlib and framebuffer ones available.
Fuse has the ability to apply essentially arbitrary filters between building its image of the Spectrum’s screen, and displaying it on the emulating machine’s monitor. These filters can be used to do various forms of smoothing, emulation of TV scanlines and various other possibilities.
