And more importantly(if it works), can you insert the DW5 SLUS into the DW5:XL ISO so it thinks you have DW5 disc in when you try to play Original with enhancements?(As all data is actually from the XL disc, nothing is really being loaded from DW5 original). Just a theory for those with the JP versions.

Oh, and if worse comes to worse, DW5:XL via HDLoader then try using a real DW5 disc. Could this work?
