The Game Boy Advance (GBA) deletes the save file when starting a Nintendo DS game because the DS uses a different save file system and structure. When the DS is initialized, it may need to clear any existing data to ensure compatibility with its own save format. This process helps prevent potential corruption or conflicts between the save files of GBA and DS games. Additionally, the DS's architecture requires exclusive access to its own game memory, which can lead to the deletion of previous game saves.
