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.
