In short: Have you ever wanted to play Minecraft inside Minecraft? It sounds crazy, but with Project Chungus 2, this idea became a reality as players created a way to play the popular sandbox game inside themselves using redstone.
Last year, Sammyuri, the redstone builder of Minecraft, created a virtual computer inside Minecraft. Use of force redstone is one of the most advanced elements in Minecraft – they were able to build a fully working computer called “Chungus 2”, equipped with a 1 Hz 8-bit processor and 256 bytes of RAM. Despite the specs, it could play games like Tetris, Snake, and Connect Four, albeit at 32×32 resolution.
Sammyuri called on fellow redstone builders Uwerta and StackDoubleFlow, as well as a few volunteers, to update Chungus 2 to complete the difficult task of playing Minecraft inside Minecraft.
It took the team over seven months to complete the VM spec update, adding another 256 bytes of RAM, a GPU they called “AMOGUS”, and 6 kilobytes of graphics memory. All this to display Minecraft on a virtual screen with a resolution of 96×96… and all this inside Minecraft.
The Minecraft world running on a virtual computer consists of an 8x8x8 piece of land made up of 16 unique blocks. Surprisingly, the development team was able to get almost all of the core features of Minecraft… (yes, Minecraft) to work.
Mining works as intended, crafting works in 2×2 and 3×3 forms, and chests can hold up to 10 item stacks. Unfortunately, you cannot mine diamonds in the world as the game is limited to iron tools. There are even little things like rotting leaves, fall damage, and gravity sand in the game.
As expected, there were some caveats to get this VM to run Minecraft. Sammyuri notes that the game runs at an approximate frame rate of “a frame every few days” without any tweaks or server changes. To make the game recognizable to viewers, the team needed to add a separate server called MChprs. (High performance Redstone Minecraft server). MChpRS speeds up the game by over 10,000 times its normal speed, allowing the virtual machine to run Minecraft at a frame rate of around 0.1 fps. And on top of that, the video is also sped up “about 2,000,000 times.”
The sheer intelligence of these redstone developers leaves no doubt that this is a “when”, not “if” situation that they manage to improve Chungus 2. Sammyuri has already confirmed that the team plans to make an effort to launch Doom on Chungus. 2 at some point in the future (of course).
