Unlocking the PSP's Dual Core Setup

Sony said one brain, fans say two — and the comments instantly went feral

TLDR: A PSP developer says Sony’s handheld had a hidden extra processor that hobbyists can now use for better fan-made games and apps. Commenters were split between retro excitement, annoyance at ad-heavy reading, and the blunt opinion that the real treasure is the linked research, not the article.

The big reveal here is deliciously sneaky: the PlayStation Portable apparently had a hidden extra brain all along. Developer m-cid has been digging into the PSP’s lesser-known helper chip, called the Media Engine, plus an even stranger sidekick tied to video and audio work, and turning all that deep research into tools other hobby coders can actually use. In plain English: old PSP homebrew projects, ports, and emulators could eventually get smoother, faster, and more ambitious because someone finally pried open hardware Sony mostly kept behind the curtain.

But the real fireworks were in the community reactions, where nostalgia, annoyance, and mild chaos all showed up at once. One commenter didn’t even make it to the discovery because, in peak internet-tragedy fashion, they said the page was "overtaken with ads" and immediately rage-quit. Another had the exact opposite energy, treating the mere appearance of Wololo like a surprise reunion episode: a full-on blast from the past for anyone who lived through the PSP hacking era. Then came the practical hot take: yes, the story is cool, but if you want the serious stuff, skip the middleman and go straight to the GitHub research. That created the thread’s tiny but juicy divide: is this a thrilling retro-tech breakthrough, or just a badly wrapped link post? Either way, the mood was clear — people love the find, but they’d also like to read it without fighting the website first.

Key Points

  • The article says the PSP includes a second processor called the Media Engine, alongside its main CPU.
  • It highlights reverse-engineering work by m-cid on the Media Engine and the lesser-documented Virtual Mobile Engine co-processor.
  • According to the article, new discoveries, including a hardware spinlock, have been turned into libraries and technical documentation for PSP homebrew developers.
  • The article says Sony’s official firmware restricted Media Engine access to the kernel, using it mainly for multimedia decoding such as MP3, AT3, JPEG, and MPEG.
  • It states that the new Media Engine libraries have already been integrated into projects including a Perfect Dark port, while VME use cases are still being explored.
