The Last Episode (Ending) of Doraemon

Have you heard about the story that is said to be the last episode of the Doraemon series? It is unofficial, yet it is very famous and widely distributed using forwarded emails since the 90's. Although the widely-known English version of the story is quite shorter than the original version which is written in Japanese, it still contains the main part of the story.

Several years later, I found this on Winny. This is the slightly different version of the ending, but the interesting part is the fact that this is presented in form of manga (comic). Again it is unofficial, it is created by 田嶋・T・安恵.
