Oh, okay, so you got the GBA repro carts.
Tomato never finished the Mother 2 GBA translation, he said the porting job on that game was so bad that he didn't see any point in it. He just translated the menus so you could work through it with a translation guide if you really wanted to.
If you were really desperate, you could install the Homebrew Launcher on your 3DS and play EarthBound that way, but the framerate might not be very good. I was thinking about buying it, since there's a 30% off coupon on MyNintendo right now, and it certainly wouldn't be the first VC game I double-dipped on ¬_¬
