Hi,

Please find http://magiclantern.wikia.com/wiki/GUI_Resources
which explains where are compressed bitmaps*, why zlib is used in the firmware, and how to decoded them.
We've got also tables on Dialog structures and strings in all languages

Attached are 'quick and dirty' scripts that can help continuing this task.

That's a step towards understanding Canon GUI and Dialogs, but there's still work to do...

just found how zlib is used at FF2D8720 to uncompress bitmap (method
#5 and #7)
not tested yet, but I think we can now use firmware zlib to decompress
our own data....
