So I recently won this auction on ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA%3AIT&rd=1
I wanted to replace my original wario ware that i lost in a move, and the twisted with no motion pak caught my eye. I figured I'd go ahead and win the auction, and the worst case scenario would be that I'd end up paying a little too much just for the original game.
But now that I've gotten it, I'm pretty sure the other cart is legit. It seems like an official Nintendo GBA cartridge, with the full version of Wario Ware Twisted, just with no motion pak, you use the D-Pad.
I haven't made it very far because using the D-Pad is weird, so I can't 100% confirm that it's the exact same game, but it seems like it's pretty close to the same one. It's fun, and a really weird experience without the pak.
Has anyone else seen one of these?
