How do you play the game Diablo 2 without using the Cd?

To play Diablo 2 without using the CD, you can use a digital version of the game, such as the one available on platforms like Blizzard's Battle.net, which allows for direct downloads and eliminates the need for physical media. Alternatively, if you have a legitimate copy of the game, you can create a no-CD patch, which modifies the game's executable file to bypass the CD check. However, be cautious with unofficial patches, as they may violate the game's terms of service or lead to compatibility issues. Always ensure that you have a legitimate copy of the game to avoid legal issues.
