MCD Demo
* MCD Demo * Here's something different to start 2026 with. A tiny demo, which was written specifically with the intention of running from a memory card via the FreePSXBoot exploit. FreePSXBoot comes with a tool for building bootable memory card images, but you can't simply boot any regular file and expect it to work as long as it's around 120KB. There are a lot of constraints to contend with, which you can read about on the exploit's GitHub page. Effectively, rather than adapting one of my smaller code examples, I have turned this into a sizecoding experiment of sorts. The demo is a self-reliant C program with a couple of asm lines for the environment setup. While the compiled file is "only" 4.7KB, it could easily be around 2KB with a custom header. This approach was used by Frog of ROi in their tiny PlayStation demos written in asm. The regular header weighs the demo down considerably. This is something to explore in the future demos, though. In the meantime, I recommend Frog's CC2024 invitation, Way and Waves. So that's it! As usual, the package contains a standalone executable and a CD image. If you want to run this from a memory card, you will have to build your own MCD image. The exploit needs to know which console model and which memory card slot you'll be using. There is no "one MCD image to rule them all" approach, unfortunately.
