It looks like from your baseband version that this is an International version running an Exynos processor. Someone will correct me if I'm wrong. I have no experience with the International version but I found this info to confirm it.

Hopefully, someone with much more experience than I can help. Sorry you've had to deal with this, but for some reason, you are missing those files that control the S Pen. I have no idea why since the S Pen is the core of the Note series. If I find any more info, I'll post it here for you.
I fear you may have a fake, or at the least, someone has messed with the software and decided to unload it on eBay. All is not lost if you can flash a legitimate ROM, if you are up for that challenge.
As a side note, I also noticed the color is off on your pictures. It may be just me but the colored band at the top of the screen looks more green to me than mine. Just an observation.
