问题：
How do emulators work? 模拟器如何工作？ When I see NES/SNES or C64 emulators, it astounds me. 当我看到NES / SNES或C64仿真器时，我感到非常惊讶。
Do you have to emulate the processor of those machines by interpreting its particular assembly instructions? 您是否需要通过解释特定的组装说明来模拟这些机器的处理器？ What else goes into it? 还有什么呢？ How are they typically designed? 它们通常是如何设计的？
Can you give any advice for someone interested in writing an emulator (particularly a game system)? 您可以为有兴趣编写模拟器（尤其是游戏系统）的人提供任何建议吗？
