Bootable? Does that mean BIOS legacy? Modern PCs can only boot UEFI binaries. (Just wondering. Of course nobody would seriosly want to use a modern PC to run that game.)

Do they not still have both modes? I haven't bought a motherboard for a couple of years, but the last few that I have have been both. (And basically I've not known or cared which I used!) Seems an unfortunate backwards compatibility loss if so.

  I don't know the details. But legacy boot mode support was supposed to be phased out between 2019 and 2021. Couldn't quickly find a good reference, here is at least some: https://www.dell.com/support/kbdoc/fi-fi/000151899/no-boot-device-found-when-you-change-the-boot-sequence-to-legacy-mode?lang=en https://www.dell.com/support/kbdoc/fi-fi/000151899/no-boot-d... Edit: UEFI class 3 is the keyword https://en.m.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface https://en.m.wikipedia.org/wiki/Unified_Extensible_Firmware_...

    Class 3 is the progressively lower class which is designed to get users to accept lesser functionality as more "modern" so therefore it must be "better" or something.

  Is there any memory tester that runs from UEFI?

    Memtest86 supports UEFI: https://www.memtest86.com/ https://www.memtest86.com/

      But the Open Source version does not v4: GPL, but legacy boot only v5-v9: Closed source, no-cost variant available, UEFI

For projects like this I like it when they go all the way and post the proven IMG file, in this case snakeos.img. How much space can it take up? Without that lots of visitors are not going to look much further at it. If the IMG was there, I would have already tested it on bare metal, if it fit on a floppy that functionality would have been confirmed bare metal too.
