Like i said: gameshark and/or gamegenie. I did have both.
Copy and pasted from gamewinners under Game Genie Codes section:
"Find Mew in red version:
151-91A-7FC
151-93A-F7E
151-9BA-5DB
Mew will be in the field west of Cerulean City."
You enter that in the device... then it will manipulate the game code.
u didnt get that from gamewinners.. you freakin memorized that shit.. ADMIT IT!! haha... muhahaha... and "mew?" dont lie.. you are obsessed with pokemon and never will stop.... MUAHAHAHAHHAHAA
