Another bad retro diskette! At first glance, this one seemed pretty much gone. None of my disk imaging tools were able to read it. Windows Explorer just crashed.

Only a low level KryoFlux dump managed to uncover the physical cause behind this: A corrupt root directory beyond any chance of repair. Luckily, both the file allocation tables as well as most of the data clusters were still in good shape. I used a hex editor to manually recover all the files from the valid tracks. It worked!

I guess these games are nothing special, but it still made me happy to pull usable data and working files from such a destroyed file system!

Collection of old DOS games on a 1.44MB floppy disk.
KryoFlux and DiskImageTool looking at this damaged floppy disk.
Manually decoding this disk's file allocation tables.
Great success! It works!

@torepang You forgot some more #cursedness:

- compiled against #MSVC and #Microsoft #Libraries, so it requires #VisualStudio on #Windows to be built and requires all apps to be linked against these libraries.

- no user accounts, everything runs on root with no password.

- SMF (Solaris) as Init & Config System.

- Keyboard is hardcoded German Neo-2 Layout.

- uses #LILO / #LOADLIN on a #FAT12 Filesystem for boot, requiring a #MSDOS Boot Floppy!

- Only supports #NTFS as filesysten.

- All manpages are in Simplified Chinese.

- System clock is local time, not Unix Time.

- Only supports #ISA & #PCI, not #PCIe or #USB!

- curl points to wget, wget points to curl.

- emacs points to neovim, nvim points to emacs.

- forced UTF-32 encoding fir everything.

- Filenames, Directories & Path must only contain Emojis and . (or / for paths).

- Files are not overwritten but instead a new copy is made and the latest version is symlinked to the original filename - like in Files-11 for VAX/VMS.

Need some more ideas for a #cursed #Linux?

For anyone woundering "why do you use the latest @linux #Kernel release?"

Well, I want OS/1337 to be basically 'rolling release' in that I can't be bothered #backporting stuff and I just want to pull the #releases straight from said projects.

github.com/OS-1337/OS1337/blob

* Okay, I've not listed #syslinux & #mkdosfs and #dd which I used in making the #Floppy image but those basically don't really change much at all. We all know how #FAT12 works...

The Last Psion | Alex

For now I'm only focusing on making something that generates FEFS24 images (24-bit pointers). That covers 99.99% of #Psion Flash and ROM SSDs.

I've only ever seen a handful of very early (1989) Type I Flash SSDs using FEFS32, and they were made by Psion themselves for the #MC200 and #MC400.

Once I've nailed FEFS24, FEFS32 will be much easier.

RAM SSDs use #FAT12, so that's a whole different ballgame. So far I've just used mtools to generate working FAT12 volumes.
