The Legend of Zelda: Oracle of Ages and Seasons GBA Edition are the Game Boy Color games in custom Game Boy Advance clear red and blue cartridges.
Now playable in the DS, DS Lite and Game Boy Micro in addition to the Gameboy Advance and GBA SP (and won’t stick out of GBA systems like the GBC carts do, bonus!).
Includes the GBA exclusive item shop. Supports password-linking between the two games which unlocks additional content.
