z80emu is a Rust library which provides building blocks for emulators based on Zilog's Z80 CPU.

z80emu was developed as an attempt to create a minimalistic emulation library. It provides the necessary tools for the retro emulators to be built upon, avoiding any assumptions about the side effects of those emulators.

Please see the documentation for a full introduction.

The repository also contains an example implementation of a complete emulator program.

Another example built on top of z80emu is the SPECTRUSTY library that focuses on "ZX Spectrum" emulators.

z80emu requires Rustc version 1.36 or greater due to the usage of some macro features and API that was introduced or stabilized in this version.

Starting from version 0.6.0, the z80emu library is released under the terms of the GNU Lesser General Public License (LGPL) version 3 or later.

Non-essential programs in this repository, i.e.: tests, examples, and benchmarks, are covered under different terms.
