Couldn't find a topic on this theme so I thought I'd start one just to point out there's a minute error in this theme's .cfg file. the name specified for the backdrop is incorrect and thus, doesn't display. The line should be changed from:
backdrop: /.rockbox/backdrops/Burnt Sunset.bmp
to:
backdrop: /.rockbox/backdrops/burntsunset.bmp
No big deal, just something I thought some might find useful. Enjoy!
