That's magnificent. I'm having trouble packing my test skin up for use though - newbie error I'll betcha. I tar the files, then gzip the tarball, but it fails to find the version (1119) - there's a \.\ folder difference between my tgz's and yours. Any tips? (XP / 7zip here)
Cath - The skins have a little text file indicating which firmware versions they are compatible with; the Penguins skin has indicators for 0828 and 1119 but not 1229, which is the firmware you're using. cM can add that to his release, or you can unpack it, add it and repack it, or I'd do it except that I'm having the aforementioned packing problem.
(Or you could go back to the 1119 firmware)
