Mew

put in the mew code on your game shark with pokemon pinball
make sure the gameshark swith is on NORM. do not have the switch to ON
get into catch 'em mode
as soon as you have C-A-T-C-H lit up and the pokéball has clamped down
IMMEDIATELY flip the gameshark switch from NORM. to ON
it will either say mew was caught (if you did it fast enough) or it will
say whichever pokemon you saw the picture of in catch 'em mode. Whichever one
it says you will still have mew in your pokédex (as long as youn turned on
the switch when the pokeball closed on the pokemon)
