## What it is
DeSmuME is an open-source Nintendo DS emulator written in C++, distributed under the GPL-2.0 license. It offers Windows, macOS (Cocoa), and Linux frontends with features like a JIT recompiler, high-resolution 3D rendering, save states, and cheat support, and is popular in the tool-assisted speedrun community.

## Use cases
- play Nintendo DS games on a PC
- run NDS ROMs on Windows, Mac, or Linux
- upscale DS 3D graphics beyond native resolution
- create tool-assisted speedruns of DS games
- use save states and cheats while playing DS games

## When to choose
- you want a mature, actively maintained Nintendo DS emulator on desktop platforms
- you need high-resolution 3D rendering or JIT speedups
- you do tool-assisted speedrunning or need frame-accurate emulation

## When to avoid

- you want to emulate 3DS or 2DS games
- you need a mobile or web-based DS emulator
