用 Rust 编写的 Chip 8 模拟器

步骤

1. 导入 chip_8_cpu_emulator。

    chip_8_cpu_emulator = "0.0.1"
            (or)
    chip_8_cpu_emulator = "*"

2. 然后在项目中使用，通过添加

    use chip_8_cpu_emulator::cpu::CPU

3. 配置 cpu 并运行。

    let mut cpu = CPU {
        registers: [0; 16],
        memory: [0; 0x1000],
        pc: 0,
        sp: 0,
        stack: [0; 16],
        i_reg: 0,
    };

    /* initializing the registers */
    cpu.registers[0] = 5;
    cpu.registers[1] = 10;
    cpu.registers[2] = 10;
    cpu.registers[3] = 10;
    
    /* store the program in memory */
    cpu.memory[0] = 0x81; cpu.memory[1] = 0x18;        // left shift reg_x
    cpu.memory[2] = 0x80; cpu.memory[3] = 0x08;        // left shift reg_x
    cpu.memory[4] = 0x00; cpu.memory[5] = 0x00;        // end of the program

4. 最后用方法运行 cpu。

    cpu.run();
