Z80# is a Z80 emulator written in C# and targeting .NET 5. It was written with the primary purpose of supporting CPC#, an Amstrad CPC464 emulator.
Currently supported:
- Cycle accurate implementation of all documented instructions
- Non-maskable interrupts
- Interrupt mode 1
- The undocumented 0xdd and 0xfd prefixed instructions
Not yet available:
- BUSRQ
- Interrupt modes 0 and 2
- Remaining undocumented instructions/behaviours
Note: The emulator doesn't pass all ZEXDOC tests and won't pass ZEXALL as the undocumented flags haven't been implemented yet. In practice I haven't seen unexpected behaviour when running software on CPC# but eventually I want both ZEXALL and ZEXDOC to pass in full.
