I've been doing a crazy amount of research, and thanks to how scattered information is, I decided to ask for a "definitive" answer: What is the best way of loading games onto an Xbox?
While I know there are varying definitions of "best" I'm mostly referring to compatibility (no random breakage) and file size (as small as possible.)
I initially assumed that CCI was the best, but due to Repackinator refusing to compress my redump ISOs (unless it was via context menu, but then I had no default.xbe), I looked into the other two methods (XISO and extracted files in a folder)
I personally find it easiest for me to just extract everything with XDVDMulleter and drop it onto my HDD, with the few test games I've used work seemingly perfect, I can't help but wonder if any issues can come from this method?
