My NES vs Nintengo

My NES is a portable, open-source NES and Famicom emulator for Windows, written in C#. It emulates NES processing, supports NTSC, PALB and DENDY formats, and implements about 97% of known documented mappers. The project says it passes most known hardware behavior tests, although some games may fail because of an unimplemented mapper or emulation bug. A built-in launcher organizes games, shows information from NesCart DB, and records ratings and play time. Users can save and load states, take snapshots, record game audio and use Game Genie. Four-player joypads work through a keyboard, joystick or Xbox 360 controller. Video can be upscaled beyond Full HD. The emulator is multithreaded, and the project reports 60 fps on older Windows machines. My NES is.NET freeware under GNU GPL version 3, listed at free. It usually runs after extracting a portable package and stores settings and user files in Documents. Requirements include.NET Framework 4, DirectX and Microsoft C++ Runtime.

Nintengo is a free NES emulator written in Go. It runs .nes files directly or inside ZIP archives and supports NTSC and PAL regions. Desktop build instructions cover Mac OS X, Linux, and Windows; a WebAssembly build can run in a browser using a local web server, with Go 1.11 or higher required for WebAssembly support. Battery-backed saves use .sav files, while save states use .nst files. Two-player netplay is available through listen and connect options. The emulator can capture JPEG screenshots, record GIF video, and record WAV audio. Its controls include keyboard input, pause and stepping, reset, save and load state, and fast-forward options. Debugging features include CPU instruction decoding, CPU and memory profiling, and an HTTP service address. Listed mapper support includes NROM, MMC1, UNROM, CNROM, MMC3, ANROM, and MMC2. Audio is a work in progress, with all channels working in some capacity. The project is published under the GPL-2.0 license.
