this works with most games, but some like blue, or firered,and i believe diamond have a
different technique(use the same move).to not get hurt(u might get hurt once, maybe twice)
all u really ahve to do is alterante throo moves, use a different one everytime.
hope it helps,enjoy!

ok first you have to ceach a abra at carulian city and go to the edge of the grassy area
in carulian next to the brige right befor you battle the guy ther teliport with abra to
the carulian pokemon center and go battle a guy with a slowpoke and teliport one more time
to the pokemon center and go to the brige and vwala you are battleing mew.

OK,put the item you want to duplicate in the 6th slot, fly to viridian and talk to the guy
who shows you how to catch a weedle. Fly to fuchsia and have a pokemon that knows surf.go
down and go to the right side of the seafoam islands. just go up and down the coast in the
water. a pokemon called Misingno.will show and either run away or attack it (if you cant
run) and now look at ur 6th item slot and ta-da! you can keep doing this if you want more
of it.

YOU MUST NOT HAVE BATTLED THE YOUNGSTER WITH A SLOPOKE LV17 AND THe GUY NEAR THE PLACE
WHERE ABRA IS. Have an abra, catch it with a drowzee (hypnosis). go to the guy near abra's
nest Do it like you would do it with gambler only use teleport instead of fly, make sure
the last pokécenter was in cerulean, go and battle youngster and head back to cerulean ,
the start menu will pop up and hit b (instead of the heading back to cerulean use teleport
and head up to nugget bridge and the start menu will appear. You can catch it with 1
pokéball U can find  missingno. and magmar/pinsir (easier to find rare pokemon)

after getting the 1st starter pokemon and handing over the oak's parcel, talk to the last
pokeball 100 times and talk to oak 100 times. Oak wil then give u the last starter
pokemon.

You can use fishing rods on statues in the gyms and wherever. You generally catch the same
kind of stuff as you would in the water outside, but it's fun or whatever.

catch a purple snorlax          then do the "hop over the gaurd" trik   and u shuld find a
lvl 999 mew
