RISC OS Software - All 32 bit neutral and tested on an IYONIX
Fat12/16/32 Disc formatter. Includes source code and also the PC version (and source code) that this is based on. Uses the same SCSIFS_SectorOp calls as Fat32Fs so probably Iyonix only.
Fat12/16/32 Disc fsck. Port of the Linux utility dosfstools-3.0.9. Includes source code and the original Linux tar/gz download. Uses the same SCSIFS_SectorOp calls as Fat32Fs so probably Iyonix only.
The original vintage Basic Editor - now 32bit neutral. Note that there is now an updated version of this included in the HardDisc4 image on the ROOL site. Only download this if you want the function key strip as a draw file.
Sound player originally by P.R.Banks. Modified to be 32 bit neutral. Used by Doom below (and included in it).
Doom built from the Linux Sources. Tested on Iyonix, Titanium and Pi 3.
Note: Releases after 3/10/19 have a file renamed - !Doom.Pwads.Database.d1.Sigil.SIGIL//msq.
If you drop over the top of the old one then you'll need to delete the old file (SIGIL/msq with only one slash).
