Mesen 0.8.1

Description

Mesen is a NES/Famicom emulator and NSF player. It is still a work in progress - some features are currently incomplete or may change in future versions.

 

Features

 

  • Other Features: 7z/zip archive support, numerous video filters (xBRZ, Scale2x, NTSC, etc.), sound recorder, sound effects, etc.
  • Stand-alone - Put the Mesen application into any folder and run it from there
  • Automatic updates - Mesen is able to check for updates and automatically install new versions of itself.
  • Built-in Debugger
  • Net Play - Play online with friends
  • Supports: Save States, Movie/Audio Recording, Screenshots, Cheat Codes
  • Support for over 195 mappers
  • NES and Famicom (including Famicom Disk System) support. Also supports: NSF, NSFe, VS System
  • High Accuracy - A lot of effort has gone into making Mesen as accurate as possible

 

Technical Details

 

  • Core built in C++ with a C# user interface.
  • Multi-threaded - Emulation, Video Filters, Rendering, Net Play and UI all run in their own threads.
  • Runs in 32-bits or 64-bits mode depending on the operating system, with the same executable file

 

The name "Mesen" is both a Japanese word (目線 - meaning "point of view" or "a person's gaze") and a terrible pun on the term "NES Emulator": "NES Emulator" → "NES Em" → "Mesen" (backwards)
