Run Windows 95 and Doom Inside Minecraft – Complete VM‑Computers Mod Guide
This tutorial explains how a Minecraft player used the VM‑Computers mod together with VirtualBox to embed a Windows 95 virtual machine in the game, install the classic DOOM shooter, and provides step‑by‑step instructions, required files, and limitations of the approach.
Overview
The VM Computers mod links Minecraft with the open‑source virtual‑machine platform VirtualBox. It streams the VirtualBox window onto an in‑game tablet, allowing a full Windows 95 installation to run inside Minecraft. Once Windows 95 is booted, classic executables such as DOOM can be launched from the virtual machine.
Prerequisites
Minecraft Java Edition (latest release).
VM Computers mod JAR file.
VirtualBox 6.1.x (e.g., 6.1.12).
Windows 95 ISO image (or any bootable ISO compatible with the mod).
Enough RAM and CPU resources to run both Minecraft and VirtualBox simultaneously.
Installation Steps
Place the downloaded VMComputers.jar into the {minecraft_folder}/mods directory.
Install VirtualBox 6.1.x from the official installer. Verify the installation by running VBoxManage --version in a command prompt.
Create the directory {minecraft_folder}/vm_computers/isos and copy the Windows 95 ISO file into it.
Start Minecraft. The mod will detect VirtualBox and create a new “Virtual Machine” entry in the in‑game tablet UI.
Open the tablet, select New Computer , and follow the UI to purchase the required components:
PC case
Motherboard
RAM module
CPU
GPU
Monitor
Keyboard and mouse (decorative only)
Right‑click the newly created computer, choose Create Hard‑Drive , attach the Windows 95 ISO, and set a reasonable disk size (e.g., 2 GB).
Power on the virtual machine. The Windows 95 installer will appear inside the Minecraft tablet. Complete the installation as you would on a physical PC.
After Windows 95 boots, copy the DOOM executable (or mount a DOOM ISO) into the virtual machine and run it. The game will render inside the Minecraft world.
Why Windows 95?
Windows 95 has a very low memory footprint (≈64 MB RAM) and modest CPU requirements, making it feasible to emulate within the constrained resources of a Minecraft mod. Newer operating systems such as Windows XP, Ubuntu, or Windows 10 demand significantly more processing power and would run far too slowly to be playable.
Limitations and Future Outlook
The current mod only supports lightweight operating systems. Attempting to run modern OSes or graphically intensive games will result in severe lag or failure to boot. Future improvements in both hardware performance and mod optimization may enable more complex virtual machines, but at present the practical ceiling remains around Windows 95‑class environments.
