iz80

Z80 Emulator library for RUST. It passes all the tests of the ZEZALL suite. No cycle emulation accuracy, runs as fast as it can.

To run the ZEXALL test suite: cargo test --release -- --nocapture --ignored

To run Tiny Basic (from cpuville): cargo run --bin cpuville

Usage

See cpuville.rs or the CP/M 2.2 emulator iz-cpm for more usage examples.

To run ths example, execute: cargo run --bin simplest

```rust use iz80::*;

fn main() { // Prepare the device let mut machine = PlainMachine::new(); let mut cpu = Cpu::new(); cpu.set_trace(true);

// Load program inline or from a file with:
//      let code = include_bytes!("XXXX.rom");
let code = [0x3c, 0xc3, 0x00, 0x00]; // INC A, JP $0000
let size = code.len();
for i in 0..size {
    machine.poke(0x0000 + i as u16, code[i]);
}

// Run emulation
cpu.registers().set_pc(0x0000);
loop {
    cpu.execute_instruction(&mut machine);

    // Examine Machine state to update the hosting device as needed.
    if cpu.registers().a() == 0x10 {
        // Let's stop
        break;
    }
}

} ```
