Mesen is a free and open-source multi-system emulator for Windows, Linux and macOS (Intel and Apple Silicon). It can emulate the Famicom (NES), Famicom Disk System (FDS), Super Famicom (SNES), GB/GBC, GBA, PC-Engine/TurboGrafx-16, SG-1000, Master System/Game Gear and WonderSwan/Color consoles.

The version currently under development is Mesen 2.x, first released as a preview build in 2023. The older Mesen 0.x branch could only emulate NES, and SNES/GB(C) emulation was found in a separate emulator named Mesen S. The current Mesen Libretro core for RetroArch is still based on the 0.x branch, but receiving backports from the newer branch. For the sake of disambiguation, we will refer to the 0.x branch as Mesen 1 and the 2.x branch as Mesen 2.

  • FDS (Famicom Disk System) support
  • Top loader NES variant support
  • VS. System support

Mesen 2 can also run GBA and also SNES games, which features some of the enhancements and hardware features such as Super FX and Satellaview support. Game Boy (DMG) and Game Boy Color (CGB) games can also be played on Mesen 2, but only Game Boy Color can play CGB games. For DMG games, you can choose either Game Boy or Game Boy Color, or run the game in Super Game Boy mode by loading the Super Game Boy BIOS (1 or 2) into the SNES core.

An exclusive feature not available in older versions is support for the PC-Engine, the CD-ROM², as well as the WonderSwan and WonderSwan Color.

Comparisons

Mesen-X
This fork was meant to centralise development efforts that were happening in multiple different forks of Mesen 1. No longer under active development, and now officially deprecated as of Mesen 2's release.

Trivia

Origins of the name essentially come from two things:

  • It's "NES EMulator", backwards -> Mesen.
  • It's the Japanese word used to talk about a person's gaze or point of view, (目線 - めせん - Mesen), which is the reason why the logo is an eye icon.[2]
