You receive the master ball in leafgreen after you stop team rocket in silph co. In saffron city as a reward from the president of silph
No!
not unless you trade one no.
You can only get one masterball.the owner of silph co gives it to you.
sorry,but they fixed tht patch you cant do it anymore
You mean Masterballs? There's only one you know.
the way to catch all legendary Pokemon in the Pokemon universe is lokk at the number they are in the pokedex then thro away that many masterballs you have to have the cheat where you get 999 masterballs to do it
The only way to get more masterballs without cheating is to have other leafgreen versions or firered or ruby or sapphire or emerald or Pokemon colosseum or Pokemon xd gale of darkness trade the masterball that those games get to leafgreen other than that you have to win the lottery in ruby and sapphire and emerald at lilycove city to get another masterball then trade it to leafgreen.
i don't think that there is a way... like i got some on mine but its still kinda a cheat. i got two gameboys, firered, leafgreen, a connector cable, and an action replay. i used the action reply to get 100 masterballs onto my leafgreen account. i gave a masterball to 6 Pokemon on my leafgreen account. i traded them to my firered account on firered i took the masterballs from the Pokemon on leafgreen i gave the Pokemon more masterballs then i traded again i just repeated this over and over until i got 100 masterballs on firered the reason i didnt want to just put the action replay directly with firered was because that account was really powerful and the action replay sometimes messes it up. my leafgreen however, was really weak so it was worth the "risk".
By using a cheat code. TOTALLY against the cheat codes. The name of the code is I believe a game shark.
This wont work, but you could try having to Pokemon hold Masterballs and mate them. Hope it works!
Personally, i do not know about emerald, BUT, I did with mu LeafGreen, and got like 99 masterballs from my brother's friend's replay.
You can buy masterballs at the pokemark with this gameshark code. Just copy and paste CF1BCCE4 F26C57D9 8BB602F7 8CEB681A
