We already know that it doesn't require to re-install OSX to enable us to run this program on any installation, and does not require to have the exact disk partition like the aTV.
However it does require you to patch Backrow.framework to change the partition "frontrow 2.0" uses as the location for the "/Media" folder.
Since there isn't (not that I could find) any guide on what to patch on the Backrow.framework, to make "frontrow 2.0" launch...I'm writing one.
I'm assuming that you already have Backrow.framework, iPhotoAccess.framework, and the patch Finder.app all installed the way you like it.
If not look else where for the guide, like here:
Guide your way to:
If it's not there go back to step 1.
Copy BackRow to your desktop, and make another backup of BackRow.
If you mess up atleast you only have to copy one file back.
Open BackRow with your prefered HEX editor.
Navigate your way to E03E0 in the editor. There should by two entry in ASCII it that should say "0s4", in HEX "30 73 34".
Change this to what ever the disk id your want to use.
Save the changes, and copy the BackRow you just modified back into:
Fix permission of the file, and your set.
Feel free to ask me for help. However if the question's answer is in the forum don't expect and answer back.
Enjoy! (Once IR emulation is done... for me... can't control the darn thing still).
