An old sea map is a map you get from mystery gift and if you have a old sea map you can catch mew. You can also get different stuff from mystery gift and catch different Pokemon like deoxys, ho-oh and lugia. But I think it is impossible to get the old sea map, why? Well because I've tried the mystery gift thing with a wireless adaptor like 100 times and still didn't work, if it worked for you, you got lucky>_<so try your best and get mew!^-^
Use action replay DS for Pokemon Diamond
you need to get it by mystery gift , with it you can get mew
Post your cartridge to Nintendo and they will download it for you. You can't get the old sea map anymore so this is the only way to do it!
Answer:Mew is inaccessible in FireRed, and can only be transferred over through trade with an Emerald game that had attended a Event for the Old Sea Map.
The Old Sea Map was an event item that allowed you to access Faraway Island where Mew resides.
You would need to get the map called the Old Sea Map through a cheating device such as a Codebreaker, Gameshark or Action Replay since the Old Sea Map was never distributed outside of Japan.
