Warning from Dave 06-12-2007:
If your image is too large you will not be able to enter the menus (thus making uploading another firmware difficult, but not impossible).
I will be releasing a new version (v1.1) very soon that checks the size of the image to prevent people making mistakes. It will also support all 3 of the Australian models (by auto-detecting the firmware version).
The following version (2.0) will suite users of Finnish Beyonwiz models. It will also have muliti-language support (user editable). The Beyonwiz models will also be user editable (for advanced users). These changes will allow BW Background Changer to keep up to date with new Beyonwiz models without me having to constantly update the application.
