It's driving me a bit crazy that it's this hard to find one in the wild.
I have the 'original' on Wii VC and have Nekketsu Downtown Monogatari for my Duo but neither of those are very easy to play while i'm standing in line for 15 minutes at Costco.
None of the dozen local shops have ever had it come in. I'm going to the Vancouver Retro Game Expo in June but no one had it for sale there or at the non-Retro Expo last year so my hopes aren't high. However there's an awesome British shop & cafe across the street so at the very least I can get a few more pounds of good black pudding.
