SpecIde is (yet another) ZX Spectrum (and, partially, Amstrad CPC) emulator. Currently, the ZX Spectrum emulation is quite accurate. The Amstrad CPC emulation is still a work in progress, but it is mostly enough for playing most games. Some of the supported features are:
- Emulation of ZX Spectrum 48K (Issue 2/3), 128K, +2, +2A and +3.
- Emulation of Amstrad CPC 464/664/6128. No support for Plus models yet!
- FDC765 disk drive emulation. (Scan commands are missing yet)
- Emulation of Spanish 128K, +2, +2A and +3.
- Emulation of Pentagon timings (but no BetaDisk yet! Sorry for that!)
- PSG (AY-3-8912/YM-2149) sound emulation.
- Turbosound emulation. Supports two and four PSG modes.
- Covox/Soundrive emulation.
- Loading of tapes via .tap and .tzx tape images, and .csw files.
- Loading of disks via .dsk disk images.
- Flashloading of .tap files and .tzx that use the ROM routines.
- Flashsaving to .tap files using the ROM routines.
- Full screen video mode detection.
- Double scan interlaced modes. (Gigascreen modes)
- Kempston/Sinclair/Cursor/Fuller joystick emulation from the PC joystick/gamepad.
- Fuller box audio.
- Works in GNU/Linux, Windows, and MacOS.
You can check the Releases page for Windows binaries.
Sometimes I keep here non-official releases:
- SpecIde for Windows 8/10 (32-bit)
- SpecIde for Windows 8/10 (64-bit)
- SpecIde for older Windows (XP/Vista/7) (32-bit)
- SpecIde for older Windows (XP/Vista/7) (64-bit)
For GNU/Linux and MacOS I'm not providing binaries yet, but SpecIde can be compiled quite easily.
- Install libboost. At least chrono, system, thread and unit_test_framework are required.
- Install libsfml 2.6.x. Audio, graphics, window and system components are required.
- Install cmake.
- Install zlib1g.
- Clone the repository:
git clone https://github.com/MartianGirl/SpecIde.git
- Go into the 'source' directory.
- Run:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=_prefix_ -Bbuild -S.
with prefix being the path where SpecIde will be installed. For instance, to install SpecIde into $HOME/bin, the order would be:cmake -CMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~ -Bbuild -S.
- Run:
cmake --build build && cmake --install build
- The binaries will be installed in 'prefix/bin'.
- Copy the roms from the spectrum-roms package (or from the Windows binaries) to the $HOME/.SpecIde/roms directory.
- Copy the fonts from the Windows binaries zip to the $HOME/.SpecIde/font directory.
- Run: bin/SpecIde [options] <TZXFile.tzx|TAPFile.tap|PZXFile.pzx|CSWFile.csw|DSKFile.dsk>
- Install brew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
- Install cmake:
brew install cmake
- Install boost:
brew install boost
- Install sfml:
brew install sfml
(SFML 2.6.x is required) - Install zlib:
brew install zlib

brew install pkgconfig
- Simlink FindSFML.cmake in cmake modules
ln -s $(brew --prefix sfml)/share/SFML/cmake/Modules/FindSFML.cmake $(brew --prefix cmake)/share/cmake/Modules/FindSFML.cmake
- Clone the repository:
git clone https://github.com/MartianGirl/SpecIde.git
- Go into the 'source' directory.
- Run:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=_prefix_ -Bbuild -S.
with prefix being the path where SpecIde will be installed. For instance, to install SpecIde into $HOME/bin, the order would be:cmake -CMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~ -Bbuild -S.
- Run:
cmake --build build && cmake --install build
- The binaries will be installed in 'prefix/bin'.
- Copy the roms from the spectrum-roms package (or from the Windows binaries) to the $HOME/Library/Application Support/SpecIde/roms directory.
- Copy the fonts from the Windows binaries zip to the $HOME/Library/Application Support/SpecIde/font directory.
- Run: bin/SpecIde [options] <TZXFile.tzx|TAPFile.tap|PZXFile.pzx|CSWFile.csw|DSKFile.dsk>
I've successfully compiled SpecIde with MinGW and Visual Studio 2015 & 2017. I've included a script RunCMake.bat that helps in the build process.
- Install and compile boost. Add the binaries to the PATH.
- Install and compile sfml. Add the binaries to the PATH.
- Install and compile zlib. Add the binaries to the PATH.
- Install cmake.
- (Optional) Install ninja-builds. It really helps building SpecIde.
- Edit the RunCMake.bat script. You need to change the lines:
set BOOST_ROOT=\<Path_to_Boost_root_directory\>
andset SFML_ROOT=\<Path_to_SFML_binaries\>
- Run:
RunCMake \[MS32|MS64\] RELEASE
- Build it!:
ninja clean & ninja install
ormingw32-make clean & mingw32-make install
(or use Visual Studio IDE) - Copy the roms from the spectrum-roms package (or find them online) to the %APPDATA%/SpecIde/roms directory.
- Download this font to the %APPDATA%/SpecIde/font directory.
- Run: bin/SpecIde [options] <TZXFile.tzx|TAPFile.tap|PZXFile.pzx|CSWFile.csw|DSKFile.dsk>
SpecIde is invoked from the command line. To run SpecIde, type:
SpecIde [options] [tapefiles|diskfiles]

- On GNU/Linux: $HOME/.SpecIde/SpecIde.cfg
- On MacOS: $HOME/Library/Application Support/SpecIde/SpecIde.cfg

This is an attempt at writing a ZX Spectrum emulator using SFML for video, audio and user interface. The goals I set for myself were:
- Accuracy. The emulator should work as much as possible like a real Spectrum. It should be easy to start in full screen mode, without having to select a video mode or care about difficult settings.
- Simplicity. The UI should be as simple as possible, and the emulator should operate only with the function keys as much as possible.
- Reliability. The emulator should never crash.
- Portability. The emulator should be easy to run in different platforms. I've been writing SpecIde mostly for learning and for trying to do a big project. So far, I am happy with the outcome! After I had the ZX Spectrum working, I thought I could try to emulate the Amstrad CPC series too, because many components are shared. So far, I've got the first three machines running, but there are still many details and problems to be fixed.
