+
+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
+
+For updates and examples on how to use this engine, check my homepage at
+http://www.komkon.org/~dekogel/
