For the emulators' developers, it's a fun coding challenge and a way to learn more about the system they're emulating as well as sharpen their coding skills. Well, I assume it must be somewhat fun for them because why else would they go through all that hard work of coding emulators without getting paid for it? 
As for the emulators' end-users, some of them use the emulators for the nostalgia certainly, others are just curious, and some others just want to play games they've never owned either because they're poor, cheapskates, or can't get those games or systems where they live. I believe most use them for the lulz though. There's just something satisfying about successfully running a game on another system it was never designed to run on especially if it can run better through enhancements in the emulator.
