Classic chiptune ending themes

Listening to good NES and Game Boy credits songs/ending themes gives me a feeling like no other. You know, they start off slow, maybe even a bit sad/retrospective, then the drums come in, and it turns into a nice upbeat tune that gives you that wonderful feel-good feeling. And the well-done ones just sound classic, even if you've never played the game. If you have, the feeling is even stronger, as you think about the experience you had playing the game (often strengthened by nostalgia).

Well, that's how it is for me anyway. What about you guys? Also, what are your favorite chiptune ending themes?

Here are some that I really like (not that varied, I know):
