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)
