A 6502 emulator written in Rust.
A 6502 emulator written in Rust.
Created for understanding the 6502 architecture and assembly. You can see the progress here, when all the instructions are implemented more examples will show up. My goal is implement all the instructions and create a hybrid platform that can work with too many different platforms. 6502 assembly is easy and fun to learn, planed hybrid platform can help other developers to learn how cpu works.
This repo has a virtual console that can be used to test the emulator. You can find it here.
```rust //Create memory space let mut mem = mem::MEM::new();
//Create CPU let mut cpu = cpu::CPU::new(&|_| { //Optional debugger see cpu::debugger });
//Reset the CPU, with start point at 0x600 cpu.reset(600, &mut mem);
/* LDA #$01; Load accumulator with 01 */ mem[600] = 0xA9; mem[601] = 0x01;
let (cycles, endingpc) = cpu.executecontinuous(&mut mem); //Print A, X, and Y registers println!("\nA: {:02x} X: {:02x} Y: {:02x}", cpu.A, cpu.X, cpu.Y);
//Print status flags println!( "| NV-BDIZC |\n| {}{}{}{}{}{}{}{} |", cpu.statusflags.N, cpu.statusflags.V, cpu.statusflags.U, cpu.statusflags.B, cpu.statusflags.D, cpu.statusflags.I, cpu.statusflags.Z, cpu.statusflags.C );
//Print program counter and stack pointer println!("PC: {} SP: {:02x}", cpu.PC, cpu.SP); //Print processor status println!("PS: {:02x}", cpu.statusflags.getps());
//Dump the memory for inspection, hex viewer is helpfull File::create("mem.dump").unwrap().write_all(&mem.data).unwrap(); ```
