Have you ever wondered what game version you had, but couldn't find out. There are 6 DS versions and 2 Lite versions and I will show you how to find them.
Step 1: Place any Game Boy Advance game in the GBA slot.
Step 2: Turn on the DS
Step 3: Go to Pictochat room A
Step 4: Remove the GBA game (thins will not damage the game, or the DS)
Step 5: Both your screens will change colour, please tell me what colour they are, and I will tell you what game version you have.
