Happy to hear that the release is coming soon.
What are the modifications you made to MSheet? If you made only osd change, MSheet is already designed to load them at boot from the osd.bin. So no need to modify the osd contained in MSheet.app.bin.
If you made modifications in the bin directory, please tell what you change and we could perhaps find a solution to keep only one version alive.
Your suggestions are always welcome.
