For gba sp or ds only
This only works for gameboy advance sp or nintendo ds...
A realy good way to trane your Pokemon is right befor you go to sleep or when your not playing the game is to put the Pokemon that you want to trane is to put them in the day care then get the acro bike and then go to one of those slippery slopes that you can only go up on with the mach bike(at this point make sure you game is plugged in the charger). Now put some thing heavy on the up button for the night, but make sure the game charging the entire time or it might die.
You might be able to do this with other platforms, but you may need fresh batteries,i wouldn't know, I us a DS.
