cuberite VS FarManager

You might be able to port a C/C++ implementation to Arduino or another language with a good ESP compiler, but that's going to be a lot of effort, and the biggest challenge you're going to face isn't RAM, it's disk space--Minecraft worlds can be GB in size, so you'll need to pair your microcontroller with, say, an SD card reader and then adapt a whole disk IO system

Shout out for Cuberite as an alternative Minecraft server project that desperately needs more volunteers

https://github.com/cuberite/cuberite

"Cuberite is a Minecraft-compatible multiplayer game server that is written in C++ and designed to be efficient with memory and CPU"

Cuberite has been demoed running on old ARM Android phones and hosting multiple players off it at once. Its performance absolutely annihilates the Java based 'vanilla' server

so basically Cuberite but more officially and with a rewritten client as well

Some have started doing this already, like Cuberite and McPy.

For minecraft server I guess it is worth trying this out: https://github.com/cuberite/cuberite

For the server you should look into Cuberite, same thing but for the server and written in C++.

There were a bunch of attempts in the past. Cuberite is still actively maintained but I have never tried them: https://github.com/cuberite/cuberite

Far Manager is a text mode tool that helps you manage files and archives in Windows, with color highlighting and sort groups. Provides a simple, intuitive interface for viewing files and directories; editing, copying and renaming files; color highlighting and sort groups and more. Multi-language, easily configurable and extensible via a library of plugins. Appreciated by Hel_OWeen.

That's alss why I consider FAR Manager to be the only legit Windows file manager.

FAR Manager

The only legitimate Norton Commander successor is FAR Manager.

There's only one legit NC clone nowadays, that is Far Manager. Initially written by Eugene Roshal (of WinRAR fame), it meanwhile is OSS.
