Yeah, I ought to go through the easy setting again, but there's more cash to be had in harder settings. And...something about hidden treasure on the hard setting?

I have heard that Rescue Rangers was an excellent game! I've only ever seen screen shots of the game though. I only had two friends and one cousin with an NES growing up, and for some reason they usually just had the Mario games. (For some crazy, crazy reason.) Maybe if nothing else, Nintendo will release it on the 3DS or Wii U Virtual Console.
