the styles will still be Panasonic copyright even though EMID has closed. I would not imagine they would mind but can't say for sure, but you would have to disclose sources etc to remain legal. The original customs are all on the cd that came with my 'Getting The Most From Your KN7000' book, and naturally I have all the updates archived. However just the 2 main sd backup files are nearly 50MB, so without actually working it out 150MB may not be enough for everything.
