This is a very accurate Z80 emulator that I wrote many years ago. It is fast,
|
|
small, easy to understand, and the code is profusely commented.
|
|
|
|
|
|
Building
|
|
========
|
|
|
|
You must first install Z <http://zeta.st>, a header-only library that provides
|
|
types and macros. This is the only dependency, the emulator does not use the
|
|
standard C library or its headers, nor does it need to be dynamically linked
|
|
against any library. Then add Z80.h and Z80.c to your project and configure
|
|
your build system so that the compiler predefines the CPU_Z80_STATIC and
|
|
CPU_Z80_USE_LOCAL_HEADER macros when compiling your sources.
|
|
|
|
If you preffer to compile the emulator as a library, you can use premake4:
|
|
|
|
$ cd building
|
|
$ premake4 gmake # generate Makefile
|
|
$ make help # list available targets
|
|
$ make [config=<configuration>] <target> # build the emulator
|
|
|
|
There is also an Xcode project in "development/Xcode" with several targets:
|
|
|
|
dynamic
|
|
Shared library.
|
|
|
|
dynamic-module
|
|
Shared library with a generic module ABI to be used in modular multi-machine
|
|
emulators.
|
|
|
|
static
|
|
Static library.
|
|
|
|
static-module
|
|
Static library with a generic CPU emulator ABI to be used in monolithic
|
|
multi-machine emulators.
|
|
|
|
|
|
Code configuration
|
|
==================
|
|
|
|
There are some predefined macros that control the compilation:
|
|
|
|
CPU_Z80_DEPENDENCIES_H
|
|
If defined, Z80.h will #include only this header as dependency. If you don't
|
|
want to use Z, you can provide your own header with the types and macros
|
|
used by the emulator.
|
|
|
|
CPU_Z80_BUILD_ABI
|
|
Builds the generic CPU emulator ABI.
|
|
|
|
CPU_Z80_BUILD_MODULE_ABI
|
|
Builds the generic module ABI. This macro also enables CPU_Z80_BUILD_ABI, so
|
|
the generic CPU emulator ABI will be built too. This option is intended to
|
|
be used when building a true module loadable at runtime with dlopen(),
|
|
LoadLibrary() or similar. The ABI module can be accessed via the weak symbol
|
|
__module_abi__.
|
|
|
|
CPU_Z80_HIDE_ABI
|
|
Makes the generic CPU emulator ABI private.
|
|
|
|
CPU_Z80_HIDE_API
|
|
Makes the public functions private.
|
|
|
|
CPU_Z80_STATIC
|
|
You need to define this to compile or use the emulator as a static library
|
|
or if you have added Z80.h and Z80.c to your project.
|
|
|
|
CPU_Z80_USE_ABI
|
|
Tells Z80.h to declare the prototype of the CPU emulator ABI.
|
|
|
|
CPU_Z80_USE_LOCAL_HEADER
|
|
Use this if you have imported Z80.h and Z80.c to your project. Z80.c will
|
|
#include "Z80.h" instead of <emulation/CPU/Z80.h>.
