R9 in the guide. However, I had no problems getting myself a brand-new one at CGE for $10 (or so) and last time I searched on Ebay (months ago) I found someone selling them brand new for a similar price, and they had 59 left in stock.
The catch is, these were all cart-only. Is this a similar situation to U.S. Last Blade, where carts were produced but a very very small amount of boxes & manuals were produced?
