Igir v5.6.0 is released. A zero-setup ROM collection manager that sorts, filters, extracts or archives, patches, and reports on collections of any size on any OS.

Igir Changelog:
Feature: CSO, ZSO, and DAX extraction without maxcso
Up until this release, Igir had been relying on the maxcso tool from unknownbrackets for extracting CSO, ZSO, and DAX files. This required extracting these compressed files to temporary files when deep scanning, increasing the time required and wear & tear on the hard drive. And depending on how the version of maxcso was compiled, it may require installing other libraries to work, making installation & usage complicated.
Igir can now read and extract CSO, ZSO, and DAX files natively, without the need for maxcso or temporary files. Users should see substantial speedups when scanning or extracting these files. This update has the added benefit that Igir can now show meaningful progress bars when processing these files.
