With the greatest respect to Eileen & Bud, they are incorrect.
The Superior Pack Styles are loaded via the YEM, hence they WILL be in the Expansion Area (unless to copy them elsewhere and delete them from the Expansion Area).
I suspect that the 35 styles referred to by Lloyd are those in the 'SX900Style_for_Genos' download, not the 50 in the 'GenosV2.0 SuperiorPack'!
The SX900 styles are supplied in a zip archive and once extracted, can be accessed either from a USB drive, or copied to Genos' User drive.
I suppose they could be imported as content into a pack created in YEM, and then if included in an installation file made from YEM would be installed in the Expansion folder on Genos, but I suspect that you would need to like doing things the hard way to use that method!
