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.

The Rest of the Story:
Peach and Daisy battled on through Duchess Zaffiro's forces. Kibidango attempts to sabotage their plans by warning the elite members of the army, but the elite still failed. After defeating the duchess, Princess Shroomla is freed, but the dog reveals himself to be Prince Haru. He then breaks a chest, revealing a map which he steals, and he gets away before anyone could do anything. Shroomla thanks Peach and Daisy for their bravery and the two princesses go back to the Mushroom Kingdom. In Royal Flush Deluxe, an additional scene is that over the course of the game, Luigi had to save Mario from the clutches of Napoleon Knight and Princess Onyx. They then decide to book a trip to Dinosaur Land a week from now to relax, with Pauline joining in.

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 which is done by pressing A in midair.

Bosses
1 stomp is equal to 5 fireballs is equal to 1 thrown object is equal to 1 hammer in damage terms.
 * Swingo (Mid-Boss of World 1): A chess knight that cheats in sports. He runs back and forth, and 3 stomps are what it takes to take him down.
 * Fou Du Roi (Boss of World 1): Champion of all the board games and sees any newcomers as a threat to her status. She throws energy discs shaped like checker pieces while walking and jumping. Takes 5 stomps.
 * Ragedeer (Mid-Boss of World 2): An angry reindeer who tires of pulling sleighs and has teamed up with Duchess Zaffiro. He attacks by dashing to the direction he faces, then turns around and launches energy boomerangs shaped like antlers. Takes 3 stomps.
 * The Gift Bandit (Boss of World 2): A really naughty elf who captured Santa and his reindeer in their vacation. He fights by throwing explosive gifts, but with correct timing, those gifts can be picked up and thrown back at him. Takes 5 hits.
 * Mecha Biokinton (Mid-Boss of World 3): A robot copy of Biokinton from Super Mario Land, this mechanical cloud was built to attack Sarsaland. It attacks by shooting Bullet Bills and moving in a circle. Takes 3 stomps.
 * Tatanga (Boss of World 3): Returning from Super Mario Land, his new attack style is launching bombs as well as firing Bullet Bills. Bombs can be picked up and thrown at him 5 times to defeat him.
 * B0W53R (Mid-Boss of World 4): A robotic Bowser prototype, it acts like the real deal. Its battle is the same as in SMB1.
 * The Royal Tank (Boss of World 4): This tank belonged to Prince Haru, and now Zaffiro is piloting it. It shoots out fireballs and blue blocks. Toss 5 blue blocks back at it to defeat it.
 * Mario Hologram (Mid-Boss of World 5): This was made by Haru for him to practice taking Mario out with a technology that creates solid light creatures. This replica fights with jumping and fire. Stomp on it thrice.
 * Prince Haru Hologram (Boss of World 5): A malfunctioning projector that uses the solid light technology goes haywire and creates a copy of the Flower Kingdom prince before it explodes, making it unable to demake it. The fight is similar to the Haru battles from TLoWZ, but without any wand enhancements at the cost of 7 hits instead of 5.
 * Fake Zaffiro (Mid-Boss of World 6): Though it looks like the real Duchess Zaffiro, it's a fake. She fights by running towards you and using her whip. She takes 3 stomps.
 * The Guard (First Boss of World 6): A guard who happens to be a sentient body of armor controlled by who else but Ursus the Eagle (who's now working for Duchess Zaffiro). This thing is immune to stomps as well as fire and ice. It attacks by walking towards the player and attempting to punch them. Another attack is throwing a cannonball that can be picked up and thrown back. Takes 5 hits.
 * Duchess Zaffiro (Final Boss of World 6): The mastermind behind this, she seeks to take over any kingdom that opposes her. Her attacks are firing magic blasts and preventing stomps by using her whip. She also drops down blocks to crush the player, but they can be picked up and thrown back at her. She destroys the blocks upon contact, but when she destroys an explosive block, it damages her. Her HP is 7.

Development
After the release of TLoWZ, Nintendo staff liked how Peach was handled, so they decided to give her her own game. The team who made this is the same as the previous game. The staff also liked how Prince Haru was added to game canon, so they decided to keep him as a part of official game canon. In the middle of development, the Super Mario Land staff decided to collaborate with the TLoWZ/Royal Flush staff, thus including Daisy and Tatanga in the game as a tie-in.
