So my cousin traded an Eevee over to me in my game Pokemon Ruby. I wanted an Umbreon, so I searched up my brain how to evolve it. You should evolve it with high friendship during night time. But how do you exactly determine day and night at Pokemon Ruby on my cartridge, since the entire game looks like its day.
It always looks like it's day, even if it's really night and the clock is running correctly. The battery is dry only if the game tells you it's dry every time you load it. To make sure it's nighttime, check the clock in your house or Birch's house in Littleroot Town. Please don't replace a working battery. You might accidentally damage your game. source: I played Emerald.
