v5.7.1

Release Highlights

Feature/fix: correct extensions for raw-copied files

Extension correction for raw-copied files (when neither the extract nor zip commands are provided, or when the zip command is provided and the zip archive is already correct) never worked correctly and caused problems with --merge-discs, so it was removed in v5.5.1. The feature has been added back, with extra tests to make sure --merge-discs keeps working correctly.

Feature: identification of many new file signatures

Extension correction relies on Igir's ability to identify file types by their contents, and support for 21 new types has been added:

• .ace (WinAce)
• .arj (MS-DOS and early Windows)
• .cab (Microsoft Cabarc)
• .cfa (Nintendo 3DS)
• .ciso (Nintendo GameCube, Nintendo Wii)
• .cxi (Nintendo 3DS)
• .dms (Commodore Amiga "disk masher system")
• .fig (Nintendo SNES Super Fighter)
• .iso (ISO-9660, UDF), including detection for some console-specific images (Panasonic 3DO, Philips CD-i, Sega CD, Sega Dreamcast, Sega Saturn, Sony PSP, Sony PlayStation 3, Xbox XISO)
• .jso (Sony PSP)
• .lz4 (legacy header; the modern header was already detected)
• .ngc (SNK Neo Geo Pocket Color)
• .ngp (SNK Neo Geo Pocket)
• .pkg (Sony PlayStation 3 / Vita, Sony PlayStation 4, Sony PlayStation 5)
• .rar (<v1.50 header; the modern header was already detected)
• .sms (Sega Master System)
• .tgc (Nintendo GameCube)
• .unf (Nintendo NES "universal NES image format")
• .vci (Sony PlayStation Vita)
• .vpk (Sony PlayStation Vita)
• .wbfs (Nintendo Wii)

Igir, and other open-source projects like it, are a labor of love. They wouldn't be nearly as meaningful without the community supporting them. Constructive feedback and general positivity will always be welcome. Be kind to others, and be kind to yourselves.
