ZX Spectrum emulator for OSX (currently 48K only), written in Swift 4
Requires Xcode 9 to build
Please see issues to check known problems. Please raise more if yours isn't there.
Collaborators welcomed.
Performance:
Pretty good when running a release build (quite a bit slower on a debug build).
Sound tends to be a bit scratchy, don't know why yet.
Kempston joystick is emulated on cursor keys and tilde (key between shift and Z) to fire
Lots of things still to do:
Joypad support
Hi-res border
Check all timings
Contended memory
Add zip support
Add Z80 file support
Add TZX/SZX file support
128K mode
AY sounds
Lots more unit tests
All included games have distribution permitted, see: http://worldofspectrum.org/archive.html
