The dancemammal editor is here now:-

For theming you will need.
1 The correct firmware for you player.
2 The firmware editor.
3 a .lst file.
4 a set of .bmps to replace the existing ones
The process is not automatic and it's time consuming, the firmware editor doesn't back up your firmware, so you need to get your firmware from somewhere else.
The most hardest and most important thing is finding the right backup firmware for your player, other wise there is a very high risk of bricking your player!
