XISO GUI - A graphical interface for extract-xiso on macOS for Xbox ISOs
So... roughly two years ago I made an Xbox emulation tutorial. The bulk of the tutorial involved dealing with Extract XISO. It's not a difficult utility use but it required a lot of steps for a non-developer like running CMAKE to build the binary, which requires homebrew to install. Writing a GUI wrapper has been on my "to-dos" ever since made the tutorial.

What in the hell is Extract XISO?
The Xbox ISO format is a proprietary disc image format used by the original Xbox console. It is based on the ISO 9660 file system but includes additional metadata and encryption specific to the Xbox. Emulators, like XEMU, on the other hand, expect standard ISOs. Extract XISO is a tool that helps to extract the contents of Xbox ISOs and convert them into standard ISO that can be used by these emulators.
Extract ISO works like the CLI utility, with a simple input and output. You can grab the release here. Right now it's not packaged completely, but it should work.
