You are doing a great work, this will requiere a lot of time ! Thanks for sharing this.

I just tried to automate the addresses translation with very few checks, so it could contain some errors.

Indeed, it's a real interesting project, I think anyone would like to customize the OS, me first
Trying to understand each part of the RPL-OS is also one of my interest and passion
I'll help you as much as I can, but my skills are limited. We'll see how far we can go, mostly depending on free times.
