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. In 2000, it was rereleased as "Royal Flush Deluxe", which is packaged with SMB2 Deluxe in a separate cartridge.

Instruction Manual Intro:
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!"

Animated Royal Flush Deluxe Intro:
It begins with a recap of SMB2, which transitions to Peach relaxing. Paratoad then shows up and hands her a letter, which transitions to mysterious events happening everywhere, starting with the Mysterious Kingdom. With Mario and Luigi missing, she decides to get to the bottom of this with Daisy as her partner. She is followed by a mysterious dog named Kibidango on her quest to solve the problem.

Gameplay
The gameplay is similar to TLoWZ, except this time, Peach and Daisy are the only playable characters. Peach has her glide ability while Daisy has a double jump.
