Hi Dustin,
I think that it is not worth a try. I've played it years ago on my ds, but only borrowed it from a friend for a few days.
It includes Bd1 in C64 style and a new game with smooth scrolling and different gameplay. The new game has not much to do with the original gameplay, and it was absolutely not interesting and challenging to me.
For old console and handheld games, you can check the site gamespot.com. There, you can find a few infos and screenshots. You can also buy the game at amazon uk, but I don't know if the seller delivers to germany, and in my opinion, it's too expensive (15 pounds).
Demanding 40 Euro (From Austria) on ebay is nuts, even if it's new!!!
You can watch the gameplay on youtube.

Or is there a full longplay of this game? Does anyone know anything about it? I'd love to play it!
