Royal Flush: Princess Sidestory

 is a game released on the Atari-Nintendo Video Advanced System, released in 1989. Just consider this to be a mix between OTL’s SMB3 ROM hacks such as Present Panic - A Princess Adventure, Peach & Daisy in The Ultimate Quest, and of course, Royal Flush - Princess Sidestory.

Story
The following text is taken directly from the instruction manual. Salutations! My name's Princess Toadstool, and when I'm not around helping the Mario brothers as usual, I just happen to do some stuff around the castle of the Mushroom Kingdom. As far as I'm concerned, nothing strange has happened today.

"Princess Toadstool! We need to talk!" "What do you mean?" "There must've been a strange occurrence going around the Mushroom World, and it's caused by the Mysterious Kingdom, ruled by the mysterious Duchess Zaffiro!" "Don't worry, my fellow servant! Looks like I'm gonna have to get to the bottom of this!" "Good luck, Princess Toadstool!"
