Release Highlights
This release brings a handful of bug fixes based on reports from community members. Thank you!
Fix: zero-byte files in zip archives
@Ooopz found a bug with copying or moving zip archives without extracting or re-zipping them. When the zip contained a zero-byte file (common with Nintendo DSi), Igir wouldn't match it correctly. This has been fixed.
Fix: large multi-file TorrentZip archives
@cmcginty found a bug with how Igir was creating TorrentZip archives with multiple files whose uncompressed size totalled >3.99GiB. This has been fixed.
TorrentZip files written with old versions of Igir are still valid zip files that Igir can read; they just aren't valid TorrentZip files. Their raw-file checksums would not have matched those of TorrentZip files produced by other ROM managers. Igir will overwrite old, invalid TorrentZip files if you provide the --overwrite-invalid option. RVZSTD files were not affected.
Fix: don't quick-scan checksums when testing files
When testing files because of the test command or the --overwrite-invalid option, checksums for files within archives in the output directory are now always calculated from their decompressed bytes. Previously, Igir might have trusted the checksums in the archive's file headers.
Fix: disc-merging GD-ROM CHDs
There was an issue where multi-disc Dreamcast GD-ROMs would duplicate the CHD for every track file if the --merge-discs option was used. This has been fixed.
