UMDGenCLI 1.1 - fixes a critical data-corruption bug in 1.0.

Fixes

  • Re-saving an opened ISO with a changed layout corrupted carried-over files (reported by the Blaze Union English Patch project): deleting/adding/renaming files before saving caused every file kept from the source ISO to be written with the source image's bytes at the file's new LBA instead of its original extent, producing unbootable ISOs. The source extent is now tracked per file (and persisted in the session state), so data is always read from the file's original position in the opened image.
  • Directory records of newly created folders now carry the real record-area size (were 0).
  • Relinked files' directory entries now carry the resolved target's size (were 0).
  • Directory "." / ".." record dates stay in sync with the build date.

Downloads

  • umdgen-win-x64.exe - 64-bit Windows
  • umdgen-win-x86.exe - 32-bit Windows

Self-contained single-file executables: no .NET runtime required, just download and run "umdgen ".
