Leveling by night.
This works with both Pokemon Sapphire and Pokemon Ruby.
It will NOT work for emerald due to the match call system allowing people to call you.(Unless found another way.)
It's pretty easy too.Read the steps below . . .
Step1:Take one,or two Pokemon you want to level.
Step2:Put them in daycare center.
Step3:Get the "Acro Bike" and go to top of desert and stand infront of slope.
Step4:Here is a tricky part.If you have a GameBoyAdvanced SP or a NintendoDS
It wont be so hard.Place a nickle on the up arrown and close the DS or SP (Close the flip screen,NOT the game!).Leave it over night and the next morning check.You might wanna put in charger too!
