My friend and I were discussing this over the weekend. Games are inherently different than movies, books, and music. They’re tied to specific hardware and operating systems that may not be available anymore.
I argue that if a game is no longer legally purchasable from the publishers or developer, it should be legally permitted to pirate it. Even EA agrees! They do not pursue copyright claims against LOTR games, as they lost the publishing license from New Line Cinemas years ago.
True but that’s how it’s always been. Most people who make emulators do it for the challenge or because they care about game preservation or both.
And they’ve done some wonderful things. One of my favourite things ever is the Nintendont launcher on the Wii. It lets you play GameCube disc images on the Wii natively. Even lets you use the normal controllers instead of having to plug in the original GameCube ones.
