Aeon is an experimental x86 PC emulator built primarily for running DOS games. It runs entirely on the .NET runtime and simulates all of the hardware and operating system functions needed for running many 16 and 32-bit DOS applications.

If you are running Windows, have a multicore processor, and are interested in .NET development or emulation, you may find Aeon interesting or even useful. If you are just looking to play an old game and stumbled across this site, feel free to give it a try, but if you want an emulator with better performance and compatibility, check out DOSBox.


While Aeon is certainly a highly-experimental emulator, it is functional; some of the features:

  • Simple to use - just open a DOS .exe or .com program
  • Emulated video display scales to fit Aeon window
  • Supports mouse input in both capturing and non-capturing modes so point & click applications are easier to use
  • Video hardware acceleration provided by Windows Presentation Foundation (requires Direct3D-capable video card)
  • Multithreaded design allows CPU emulation, graphics rendering, and audio emulation to be performed in parallel on multi-core processors.
  • 100% managed code: runs natively on either 32 or 64-bit Windows
  • Emulated Hardware
  • 486 processor (real-mode and protected-mode)
  • Generic PC BIOS
  • Generic VGA card
  • Keyboard/mouse input
  • Intel 8259 PIC (Interrupt Controller)
  • Intel 8254 PIT (Timer)
  • SoundBlaster 2.0 OPL3 FM sythesizer
  • SoundBlaster 16 DSP
  • General MIDI output
  • Intel 8237 DMA controller
  • VESA 2 compatible SVGA card
  • MSCDEX CD-ROM interface
