ILLusions0fGrander released a new version of RarTo360 - a simple app to extract iso contents to 360 via FTP -- if using RAR, it will extract the ISO from the archive then transfer ISO contents on the fly to the 360 (minus the $SystemUpdate folder)

What's new/fixed:
* using newer exiso.exe that skips $SystemUpdate folder altogether
