OK so first you will need to win the Master Rank of the Pokemon Contest to one Pokemon then talk to the painter and it will be in the museum.
If you win a Master Rank contest, a picture of your winning Pokemon will appear there. Cool contest - red frame, beauty contest - blue frame, and so on.
You can only get a master ball in the team magma base near lilycove city in ruby or emerald.
you have to defeat the elite 4 and i think you have to win a master contest. not sure though. just beat the elite 4 and if the word still doesnt show up then beat a master contest. then it should definitely pop up
In Pokemon Ruby/Sapphire/Emerald you go to the PokeMart building in Lilycove city to try the lottery once a day. It depends on your Pokemon ID number. You get better chances of winning by trading Pokemon with various people. First Prize is a Master Ball.
