Wait you mean they made a Rainbow Islands for the DS?
From when I might have it archived. I think?
Personally I like the gbc game itself and if your looking to order anything in games try my most revered comic/game store "
Bullet Proof"
1-718-434-1800,
1-718-434-8512, and FAX is
1-718-434-8514
The number is for the the most active store. They are like the most friendliest store in the entire NYC area. Unlike other comic book stores or game store they are into both Games and Comics.
You can ask for anything in the imaginary
Anime
Posters
Figures
Books
Manga
Imports
Cards
They even have Atari games in stock.
If your a watcher of Anime they will have your tape no matter what just ask them and they will have it.
It's also good to keep rounds on the stores in person since I found Evangelion the N64 game selling for $20 where other places will sell it for $90.
All the people there are into games and comics like crazy.
Trust me if you want it they will have it.
