I found out recently that a lot/some of homebrew projects have a EFS version release (
using this I believe?), which is the whole game/application in one .nds file.
Would it be impossible for you to do such a compilation and release for those who's only got the emulator?
I understand that it would make loading custom levels impossible but then you could perhaps just compile a few levels into the package for instance the tutorial (obviously) and The Machine. Just to show how well it's actually running atm.
