you cant
There is no way. Missigno (Its Missigno) is a glitch, and can only be accessed in any game with a cheating device. Also, DON'T GET IT, because it will mess up your game in some way. If a roaming Pokemon appears on the map and there weren't any before, avoid it. Also, if a roaming Pokemon is already on your map before, good luck. If you encounter Missigno, RUN.
Hey!!!!!!!! One way you can get a missigno in Peral/Diamond is Astion Replay DS. You can get it at Gamespot. Or if you already caught one in another Pokemon game, you can get it again at the Pal Park, IF YOU HAD IT IN ANOTHER GAME!!!!!!!!!!!!!!!!!!! I hope my advice helped you!
I believe it is only a glitch or a hack that should not exist.
Misingno is is a glitch Pokemon in Pokemon red, blue and yellow. It's possible to find it by the old man glitch and the mew glitch.
You do not find or capture pokemon. Imported glitches cannot be used. Sorry.
