Additional notes:

I'm very inexperienced with using xmemcompress for applicable use-cases, massive thank you to Razor12911 for providing the config (attached below), to process the "*.xnb" containers, other community tools that are able to parse other XNA titles using "*.xnb" containers, weren't able to with those compressed using LZX. Attached is said config. In comparison with other published results, there's a minimum of 640MiB in potential gains left on the table, alas I can't for the life of me figure out where though. As this is the first LZX-compressed XNA title I've approached, it's entirely possible I'm just missing something obvious.
