I'm trying to use either of these features so I don't have to copy games over to my console. With the DVD emulation tool, any ISO I give it comes back with an "invalid character" error, and I just can't seem to get the remote file share to come up in the shell @lllsondowlll had an old thread about this, but the pics are all dead @XboxSurgeon ?
Do you have the harddrive setup to work with it? I cant remember if you need to build the ISO using the XDK provided tools (also make sure its something your console can handle, dev patched or whatever).
You need to rebuild the ISO using the SDK and for SMB just make sure its locked to the PC that's holding the games then expose a folder to your network from said PC. I have done both and can say DVDEmu is great all around but SMB while fantastic for debug is not great for casual play since games will lose performance. EDIT: Should mention you need to tell the XDK what location it needs to look at for the SMB share, Read the SDK docs cause it goes into slightly better detail :/
