iXiso is a nifty little OSX frontend for in's extract-xiso tool. Its actually pure applescript (+ a lil bash hacking).
I started to mess with Xcode, but soon found it to be cumbersome.
What it does:
This little fella will extract a given Xbox 360 xiso file to a given folder.
It was initially designed to function as a droplet:
just drop an .iso file on the app and it will ask you for a folder to extract to.
If no file is dropped on the app, it will ask you for an .iso file.
Why for god's sake?
I wanted to get xiso extraction done on my mac with as few clicks as possible.
I wrote this because i thought it might come in handy.
If you dont like it - dont use it.
