you trade for it from emerald.
GameShark is the only other way.
its impossible without gameshark or action replay.
I tried to do all cheats without the gameshark but theres nothing in the cerulean cave,sorry. I want a mew to but no way.......
First you go and get a gameshark.
i do not think its possible without those gameshark things or something like that,but you could buy a gameshark ;) but thats all i can think of. you can buy a gameshark off of ebay.....i think.
You can't. it's true. you can't sorry.
it is not possible to get mew in Pokemon Ruby unless you use a gameshark code. however it WAS possible to get in emerald prior to an event. Sadly it has passed.
you didn´t get mew qith any cheats in ruby =( you can get mew with an mew-glitch in yellow (blue,red) or you can get a mew from my Pokemon ranch for diamant perl and platin but not for ruby the way to get mew in ruby is ... on a Pokemon tour (Pokemon-day ... , ) or with an cheat ... i hope i can help you :-)
you have to trade from emerald
Gameshark codes.
you buy an gameshark then you catch him in emaerald or ruby or sapphire then you transfer him to diamond
No
