Ok, so I've extracted my own firmware and made an extra copy. I then edited the firmware with a static start menu which didn't look really good when it was on the player. I decided to look for a pre-made mod and from all on the forums, I liked Tadad's theme most:

However, the file does not have any extension and cannot be opened by the editor 2.0. Does anybody have the bmp for it in 24bit? I've read the comments and several other people have had the same problem with no solution. Tadad hasn't been active apparently for about a year =\
