Want to play Ruby or Sapphire on your TV but have no Gameboy Player? Well POKéMON Box's adventure mode is just what you need!
Just follow the on-screen instructions and soon you'll be saving on batteries heh. There are some differences from the Gameboy Player however.
Sadly POKéMON Fire Red and Leaf Green cannot be used in conjunction with the Adventure mode. It's still a worthy feature, but there is a reason Ruby & Sapphire is in the title.
You can't change the screen size to full-screen nor can you change the background images. Also you must keep your GBA and game linked to the Gamecube the whole time you play even though you can turn the GBA's power off.
One last thing is the ability to take an in-game snapshot of the screen or battle you're currently on. Only one snapshot can be saved at a time however and will be sent to the Special My Wallpaper section in Box mode. You can then use that picture as a wallpaper background for your storage boxes!
