If it has subfolders like WeatherPanel does, you'll need to get creative with your initflashfiles.txt. Check out my WeatherPanel oem and you'll see what I mean:
ftp://ppcgeeks:ezupload@up.ppcgeeks....atherPanel.rar
Basically, you'll have to copy files into subdirectories of the windows folder. This can get tedious and will take up valuable space. It's not impossible though, so give it a shot

Actually, check out Sogarth's PocketWeather OEM. That should help you devise a game plan.
