Finding a safe and legitimate way to experience depends on whether you are looking for the original 1992 retro classic or modern ways to play the game on current hardware.
If you see links for a "new" Darkwing Duck game download, be careful. A AAA modern Darkwing Duck game has not been released. However, there is a fantastic fan-made game called Darkwing Duck: Just Us Justice Ducks (Demo). While free, these are not "normal" commercial links and require patching.
