This package contains a portable Z80 emulator. It includes two engines: One
|
||
|
|
written in pure C, which can be used on just about every 32+ bit system, and
|
||
|
|
one optimised for GCC/x86 (DJGPP, Linux, FreeBSD). It can be used to emulate
|
||
|
|
systems with multiple Z80s and systems with several different CPUs
|
||
|
|
You can use in your own applications, as long as proper credit is given,
|
||
|
|
no profit is made and I am notified. If you want to use this code for
|
||
|
|
commercial purposes, e.g. using it in commercial projects, selling it, etc.,
|
||
|
|
please contact me
|
||
|
|
|
||
|
|
To use the code, check the system dependent part of Z80.h, write your own
|
||
|
|
memory and I/O functions, which are declared in Z80IO.h, write your own
|
||
|
|
Interrupt(), Z80_Patch(), Z80_Reti() and Z80_Retn() functions, initialise
|
||
|
|
the Z80_IPeriod and Z80_IRQ variables, call Z80_Reset() to reset all registers
|
||
|
|
to their initial values or call Z80_SetRegs() to set all of them to pre-loaded
|
||
|
|
ones, and finally call Z80() or repeatedly call Z80_Execute(), the latter
|
||
|
|
option should be used in multi-processor emulations
