Nintengo review
A free, cross-platform NES emulator with browser support, saves, and two-player netplay.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nintengo is an open-source Nintendo Entertainment System emulator written in Go. It is aimed at users who want to run NES ROM files across Windows, macOS, Linux, or a browser. The emulator supports standard .nes files as well as .nes files inside ZIP archives, making it suited to users who keep ROM collections in either format. Its free, open-source model also fits users who prefer software without commercial plan tiers.
Its strongest practical feature set centers on game progress and multiplayer. Save states are stored as .nst files, while battery-backed saves use .sav files, giving users two distinct ways to preserve progress. Two-player netplay adds online play for supported sessions, and NTSC and PAL region emulation provides options for games associated with either format. Configurable speed controls are also included. The documented WebAssembly build extends the emulator beyond desktop systems, while the Windows, macOS, and Linux builds cover the main desktop platforms.
Nintengo also includes recording and debugging tools, with options for screenshots, GIF, JPEG, and WAV output, plus CPU and PPU behavior debugging. That breadth makes it more than a basic ROM loader, but its focus remains specifically on NES emulation. Users looking for a narrowly focused, free emulator with cross-platform access, save support, and two-player netplay should consider it. Those seeking emulation across multiple console generations or a wider multiplayer scope should choose a product built around broader system coverage instead.
