Black Mamba Theme

trying to get Goodbye Black Mamba Linksheet here

http://community.wdc.com/t5/WD-TV-Live-Hub-Themes/Theme-GoodBye-Black-Mamba-LinkSheet-Updated-Dec-14th/td-p/510386

to work with newest firmware and hoping to use the usb thumb method to show the sheets as per here

http://forum.wdlxtv.com/viewtopic.php?f=63&t=7665

any ideas how to set this value with SMP

config_tool -c THEME_PATH="/path/to/root/of/theme

…do I set this in the theme or the SMP? Also if I have a front thumb drive what will be the path if the theme is /X/ for example?

is there an alternative area to store the sheets instead that will bypass the 30mb limit for themes?
thanks in advance
