Dendy vs My NES

Dendy is a free NES/Famicom emulator written in Go, with desktop versions for Windows, macOS, and Linux and a WebAssembly version for modern browsers. The desktop program has no graphical interface and runs from the command line with a .nes ROM file. Player one can use a keyboard or a detected gamepad, and a mouse can emulate the Zapper light gun. Options include save-state control, rewind, screenshots, CRT effects, and Game Genie codes. Network multiplayer uses rollback networking and peer-to-peer connections. A public relay can help players behind NATs find peers and connect, though it will not work if both players are behind symmetric NATs. Users can also build and run their own relay. The browser version does not currently support netplay. The maker cautions that Dendy may not match established emulators in accuracy or compatibility, so some games may not run. Sound emulation is still in progress and may produce pops and crackles. The project is MIT-licensed.

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.
