Complete Guide to Emulators for Older Operating Systems

Last update: May 31th 2026
  • Browser-based emulation options that require no installation for experimenting with retro software.
  • Advanced virtualization tools for running full versions of Windows and DOS on modern hardware.
  • Software specialized in running classic games and graphic adventures through compatibility layers.

Older operating systems

If you look back, just a few decades ago computing was a completely different world. We lived in an era where having 1 MB RAM It was everyone's dream, and managing files with floppy disks was the absolute norm. It's crazy to think that back then, not even the movies dared to imagine that we'd have artificial intelligence running on a home computer.

For those of us who remember those years with nostalgia, trying to replicate that experience today can be a real headache due to the incompatibility of modern hardware. However, thanks to the Retrocomputing and emulationIt is possible to recover those memories and interact again with the environments that defined personal computing.

PCjs: An interactive library in your browser

Retro PC emulator

If you don't want the hassle of installing programs, PCjs is a fantastic option. It's not a conventional emulator, but a interactive library based on JavaScript It allows you to explore the history of computing directly from the web. It's ideal for those seeking instant gratification without setting up complex virtual machines.

This project pays homage to milestones such as the IBM PC 5150 from 1981, the computer that set the industry standard thanks to its open architectureIn PCjs you can tinker with systems like MS-DOS, Windows 1.0, 3.0, 3.1 and even the legendary Windows 95, as well as less common environments like OS/2 or CP/M-86.

In addition to operating systems, you can run legendary applications like Lotus 1-2-3 or WordPerfect, and play classics like Wolfenstein 3D or The Oregon Trail. The tool faithfully emulates the hardware, including CGA, EGA, and VGA video adapters, although you should know that There is no data persistenceTherefore, anything you save will be deleted when you close the tab.

Virtualization with VirtualBox for Windows 98

Virtualization of legacy Windows

When you need a more robust and persistent environment, virtualization is the way to go. Windows 11, for example, only supports 32-bit applications thanks to WoW64, leaving out 16-bit software. To address this, VirtualBox is the free tool most recommended for setting up a Windows 98 virtual machine.

The process involves downloading the system's ISO (often available on the Internet Archive) and configuring a machine with modest resources, since 256 MB of RAM These are more than enough for the system to fly. A critical point is driver management; to avoid the basic 640x480 resolution, it's necessary to install third-party drivers that allow you to achieve higher resolutions. high color density and higher resolutions.

To move files between your current PC and the virtual machine, since Guest Additions are not usually compatible with such old versions, the best alternative is share folders over the network Locally configuring the Microsoft network client within the Windows 98 control panel.

The DOSBox ecosystem and specialized emulators

If your goal is purely to play command-line games, setting up an entire operating system is overkill. In this sense, DOSBox is the undisputed kingIt is a lightweight software that emulates the MS-DOS environment and is so effective that platforms like Steam or GOG use it for their retro games.

With DOSBox you can configure the processor (from a 286 to a 486) and choose the sound card, such as the Sound Blaster. You just need to use the command mount to link a folder on your real hard drive to the emulator's virtual drive and start playing in no time, similar to how some are used Linux tricks and commands in the modern terminal.

On the other hand, there are more concrete alternatives. SCUMMVM is the jewel For fans of LucasFilm Games' graphic adventures, this is ideal, as it focuses on running the game rather than emulating the entire operating system, drastically reducing crashes. For those seeking something more geared towards older productivity applications, VDOS Plus It is a stable fork designed to run outdated spreadsheets and databases.

Quick explorations: EmuOS and Virtual x86

For those who prefer total immediacy, there are projects like EmuOS on EmupediaIt's basically a visual simulator that lets you jump between Windows 95, 98, and Me with a click. It's not a real installation, but a recreated experience that even includes programs like Winamp and games like Diablo. live the retro experience without complications.

Almost along the same lines we find Virtual x86This emulator, written in JavaScript, is capable of virtualizing x86 architectures from within the browser. It comes with pre-installed systems such as KolibriOS or Linux 2.6, but also allows you to load your own hard drive or floppy disk images, offering a surprising stability despite being in the experimental phase.

If you're looking for an extreme solution, there are operating systems specifically designed for emulation that boot directly when you turn on your PC, bypassing Windows. While they require more technical knowledge, they allow you to turn any computer into a multi-game console total.

The ability to rescue old software through emulation and virtualization allows us not only to play games, but also to understand the technical evolution of our era. Whether through lightweight cloud solutions or complex virtual machine configurations, today we have the possibility of keeping alive the legacy of the first personal computers without giving up the power of current technology.
