Neko - Minecraft Hacked Client

Context

Neko was a free Minecraft Hacked Client in v1.8 exclusively french with 100+ cheats (a lot of unique ones), started in 2016 and finished in 2022. That was my first ever coding project, started in my CFC (Swiss apprenticeship).

It had the following features:

• A lot of unique cheats
• The first public cheat client with an unlimited entity reach
• An IRC chat to talk with other users using a webserver
• An RPG system with levels, stats, titles that give you bonuses and highlighted servers where you can get more XP

There were more than 1000 users using the client, and I was very proud of it.

Now, the code of the project is available on GitHub.

Motivation

I played a lot of Minecraft with multiple cheats. However, on one of the servers I played (Epicube), the anti-cheat developer (Likaos) managed to detect the current cheat I was using. So I decided to make my own to be able to change the code and avoid the detection directly.

I also really wanted to create a game, so in the precipitation, I included some game concepts in the client like the RPG system.

Game-like features

To earn xp, bonus blocks (meteors) were appearing around the player, which needed to go on it to receive something:

• XP to level up
• Souls (money) to play title gacha
• Titles that give you bonuses

Players need to earn level or gather a title to unlock some cheats.

Titles had unlimited levels, and the higher the level, the more bonus you get. Each one has a rarity and a color that you can equip, it was shown next to the player name in the IRC chat.

Some servers were highlighted, that was servers I liked to cheat on, and where you could get more XP. Technically, it was like launching a raid on a server indirectly.

Development

I used a minecraft MCP (Mod Coder Pack) with Optifine mod to improve the FPS and the rendering of the game to make the base of the client. I followed a tutorial at first to understand how to make a hacked client, that I understood correctly way later.
