createnpk.py for 6.x packages

Hi,

I noticed that createnpk.py was made only to create 2.9.x packages and it lacks support for 6.x.
Digging into it a little more, I modified the header's hexadecimal values (with a hex editor, comparing the apropriated values with an actual 6.43.4 package) in order to "fake" a 6.43.4 package, however I noticed that the package made with createnpk.py has an old header format and the 6.x has a larger header and it has even a small footer.
Whenever I try to install the package with RouterOS it looks for a package called system-6.43.4 which is already installed however the new package name is just plain "system" and it has a version argument containing its version number.
The specific error is something like "Cannot install dude-6.43.4. Requires system-6.43.4 which is not installed"

That said, do you think would it be possible to write a new tool to encapsulate the 6.42+ squashfs package with npk?

I'm asking this because the oposite is true, we can unpack the npks with unnpk.

Thank you

Regression - original npk format

Unpacking of original npk files (e.g. http://mirror.mikrotik-bg.net/Dude/4.0beta3/dude-4.0beta3.npk) doesn't work anymore. Reverting the last update (support for the new format) solves the issue.

With 6.12 unpack works correctly.
Some changes? (like backup)
thanks

Not able to unpack 6.40

It works on 6.20, but not 6.40. Hope it would be fix soon.

btw, hank you very much for your great work here. With your work we can pry into the mikrotik package and see what they are doing.

Best wishes.
