libz80 - Z80 emulation library 

===============================

*© Gabriel Gambetta ([email protected]) 2000 - 2014*

*Version 2.1.1*

Building and Installing

-----------------------

The Makefile creates `libz80.so`, which together with `z80.h` make up the binary

package. `make install` installs these files in `/usr/lib` and `/usr/include`

respectively.

Emulation code itself is generated by the `codegen` directory. `mktables.spec`

includes a specification of the opcodes, using regular expressions to express

similar opcodes in a compact way. Binary representation of the opcodes is listed

in `opcodes.lst`. This makes tweaking the 'processor' relatively easy, as it

isn't done manually.

Pre-generated files are included - these are `opcodes_decl.h`, `opcodes_table.h`

and `opcodes_impl.c` in the `codegen` directory.

The `tests` directory includes a simple test framework and a few tests to ensure

the current behavior of the processor.
