Craft4k

A highly accurate recreation of Notch's "Minecraft 4k" content created by NodeMixaholic. (Renamed so Microsoft doesn't come after me.)

Notes

This project has no relation to "Minecraft", "Mojang", "Microsoft", or "Notch". Just a simple dev trying to do stupid stuffs.
I have no proof, however this was painstakingly decompiled (from highly obfuscated code), recreated (from highly outdated code), and remastered (so it's slightly less wonky) by NodeMixaholic.
I have deep respect for Notch's work - even if I don't agree with everything he may or may not have/will said/say.
This project does not have a focus on being 4kb in size. I know, boo-hoo.
Shoutouts to ChatGPT for being smart enough to aide me through this task.
I grabbed the original .jar file from here, I think.
This is mostly rewritten.
- The majority of the functions are rewritten from some semi-deobfuscated code.
- However, this code was also obfuscated in a way - such as variables having different names. This is normal for so-called "deobfuscated code".
- And, thanks to ChatGPT getting a bit confused due to context length (since I did this logged out), and me asking for a version that can run in Java 25, it did mostly a rewrite using my semi-deobfuscated code as a reference.
- TLDR: Everything for this project has had to be rewritten and modernized due to it's design - from the rendering (painting/repainting), to the launching of the game, the movement, etc.

Grab a copy of the source code and OpenJDK 25.
Use the command javac Craft4k.java Launcher.java compile.
Use jar cfm Craft4k.jar manifest.txt *.class if you want to jar for distribution!
use java -jar Craft4k.jar to run if made for distribution, java Launcher if not (note: no ".class"!)

There sure is! Just go here to download a pre-compiled, (hopefully) semi-stable jar, and go directly to step 4!
