It's actually the 2nd calc OS in terms of how far it progressed so far. It stalled for a while so GlassOS became first but now that KOS resumed I guess they might eventually be even depending of how fast they progress. Hopefully there is good compatibility between both for ASM programs. (and backward compatibility with some TI-OS games)

woo, this is awesome that it is in development again!

I can do german

EDIT: Where are the dialogs for that?

EDIT2: found it out >.>

EDIT3: here is my german translation

EDIT4: I promise, no more edits

You should make an account on GitHub and make a "fork" of KnightOS. It took me a while to figure it out since i've never used git/github before, so here's what i did:
1. You need "git" installed.
2. Make an account on github.com, and click "fork" on the KnightOS github page.
3. Choose a directory for the project to go into (it will create a directory called KnightOS there)
4. From the terminal/command prompt: "git clone [address of your cloned project]". For me, this was "git clone https://github.com/chickendude/KnightOS/"
5. Go into the lang folder and create a folder with your language name (nl_be, de, es, etc.) and copy your translated files. Make sure they are encoded in ANSI (Windows-1252) (not UTF-8 or some other format). I think files written in Notepad are ANSI by default.
6. From the terminal "git commit"
7. Again, from the terminal "git push". You will need to type in your username followed by your password, and it will upload your changes to your fork.
8. Now all you have to do is log on to github, go to your KnightOS fork, and make a pull request (there's a button above the project that says "Make a pull request") and you're done.

It took me a while to figure it out, but once you get everything figured out altogether it takes less than a minute from the initial download of the project to the final push. In the future, when updating your files, just go into your KnightOS git project directory and run "get pull" to make sure there haven't been any changes since you last updated. There are also some GUIs, but i couldn't figure out how to get any of them to "push" the changes to the internet

Again, make sure that the files are ANSI formatted!

I'd be more than happy to help anyone who's having trouble

I got to the git commit, then suddenly this window appears and I don't know how to save or confirm or do whatever I'm supposed to do

that's vim, a text editor. you need to type in a commit message on one of the lines that isn't commented out by a #, press [shift]+[:], and then type wq (write and quit).

EDIT: oh, and to type things in, you'll need to move the cursor to the spot where you want to start, hit a letter key once to enter insert mode, type what you want, and hit esc (there's probably a better way to do this, but i don't use vi/m)
