Z80Core
A Z80 core written in Java.
This core is a slightly modified core extracted from JSpeccy, ready to be used at any emulator that needs a Z80 CPU.
This code emulates the Z80 CPU full instruction set including:
- Undocumented instructions as SLL.
- Undocumented flags 3 & 5 from F register.
- Hidden register MEMPTR (known as WZ in official Zilog documentation).
- Strict execution order for every instruction.
- Precise timing for all instructions, totally decoupled from the core
An example that executes the CP/M v2.2 tests ZEXALL & ZEXDOC is included as an use case.
