I had asked this question earlier, but then thought I'd found the answer so I deleted my post. Turns out I still need some help. Here's the post I posted in the Sense SDK thread. I figured maybe some of the big ballers here might have an answer...
" I'd like to skin all the HTC green in SenseSDK to a blue. I saw Dwizzy's post
here and the .cab and EXT he made using eboelzner's files. These are supposed to be for skinning right? I've tried that .cab but things look the same. I then switched out all the green PNGs for blue ones thinking that maybe I just couldn't tell difference in the green ones, but still nothing changed. I've not tried his EXT yet.
I also have 3 or 4 apps in my ROM that use SenseSDK. Is it possible to skin SenseSDK in apps that have already been cooked into a ROM or does this need to be done by the author of each app?"
