Somski released a new version of Xbox 360 ISO Extract (exiso) - an exiso based extractor with FTP support which can extract multiple isos.

What's new/fixed:
* I've updated exiso to support XGD3 images, just change the exiso executable and you should be fine.

ToDo:
* A new version of the extractor with a better status bar might follow.
