Essentially, this is:

- A rudimentary preemptive RTOS

- Using an unmodified NES emulator (FCEUX) as the CPU

    - "Unmodified" depending on how you define terms\n

\n- With emulator save states as the thread contexts

- With support for (very basic) mutexes, interrupt masking, and condition variables

- Demonstrated using Super Mario Bros. 1-1 with sections of the map dedicated to various synchronization primitives

There are many simplifications and shortcuts taken (doesn't even have task priorities), and it doesn't map 1:1 to true multithreading (e.g., emulator save states represent the state of the entire machine including RAM, whereas thread contexts represent a much more minimal slice), but I think it's A) pretty interesting and B) a unique visceral explanation of threads.","time":1748463343,"title":"A toy RTOS inside Super Mario Bros. using emulator save states","type":"story","url":"https://prettygoodblog.com/p/what-threads-are-part-2"}],[44079331,{"by":"ljf","descendants":5,"id":44079331,"kids":[44079940,44089334,44082066,44082019],"score":50,"time":1748070768,"title":"A boy who came back: the near-death, and changed life, of my son Max","type":"story","url":"https://www.theguardian.com/lifeandstyle/2025/may/24/the-boy-who-came-back-the-near-death-and-changed-life-of-my-son-max"}]]
