IsoBuster 5.4.1 Released!

June 05, 2024

I'm very happy to announce the release of IsoBuster 5.4.1.

See the list below for all the goodies:

Changes / New:

  • *.PFR Image file support
  • *.IMZ Image file support (Multiple images supported, but limit currently set to 20)
  • *.ZL and *.ZZ Image file support (zlib compressed image files (similar to the *.GZ functionality)) (*)
  • *.ZIP Image file support (For single-file image files that are compressed in a zip file) (*)
  • *.QCOW2 Image file support (current snapshot, no encryption)
  • PartClone Image file support
  • NTFSClone Image file support (versions 10.0 and higher)
  • Support for Kurzweil K2000 synthesizer FAT 16 diskettes
  • Support for DOS 1.0 style FAT12 floppies without a BPB (Bios Parameter Block)
  • Support for Roland (Synthesizer) Audio CDs, Zip disks and images
  • Support for ReFS version 3.10
  • Ability to load a generic image file from and offset and with a range. Syntax: \\#\(1024,51200)i:\images\file.iso (for instance via imlst)

*.gz, *.zip, *.zl, *.zz etc. compressed file formats don't support random access, so IsoBuster has to index the files internally while loading them. For huge files his can take a minute or two.

  • Fix printing from the edit window in 64 bit mode
  • Fix for larger ReFS 3.x volumes where the root could not be found
  • Fixed making corrupt ~4GB *.gzndx files for huge *.gz files in 32 bit mode
  • Opening a split *.gz.00? file via the *.gzndx file now works properly (before it would not find the *.001 file)
  • Version 5.4.1 fixes some regression in 5.4, in particular when opening generic image files
