Yeah you just need to copy your tune settings to the new OS file. Then rewrite your PCM with the new OS.

I read the docs, and can't find out how to do that.

I would think it's just like loading a custom OS, try looking at that tutorial and see if it helps at all.

I did read that before, but as there is no "tun" file, there is no option for that.
