I know it's not any single game, but a good go-to site for legal abandonware is
www.abandonia.com. It's a good site to find most anything worth playing (and some that sadly isn't), with the added bonus of not distributing ESA-listed games they have listed and directing you to the parent companies of games you can still buy. They also point you toward several programs that you can use to run non-XP compatible DOS games.
