This is the SIBO Image Extractor, designed to extract files from Psion Solid State Disk images. In future it might also build images for copying/burning to SSDs.
THIS IS ALPHA-QUALITY SOFTWARE! It's worked for me, but it might not work for you.
For Linux, BSD, macOS and other POSIX-compliant systems.
make
For Windows you will need MinGW and either gcc or clang. Pre-made binaries can be found in releases.
siboimg _image file_
At the moment the switches don't work so all it does it extract the files to a directory. The directory will be named after the image's embedded name.
Thanks to Clive DW Feather for his description of the SIBO Flash filesystem. Thanks to Karl for helping me out.
