From the article:
> All files required to run each game must fit within 1.44MB. Entries must be standalone games that run without a separate server or internet connection, and the size limit includes every required component, including game engines and libraries.
Booting on what? Are BIOS calls (if allowed) considered a library? The overhead of managing a framebuffer etc without an OS (which would be a required component not included on the disk) feels like it would dominate.
