Sonic 1 on Bird Hill Island Demo By Blue Gamer Hello everyone and welcome to the newest demo of Sonic 1 on Bird Hill Island! Before we start with the changes compared to the last demo, most people haven't played this hack before so these are the changes from Base Sonic 1: new level design new color palettes for EACH ACT new characters 1 new zone new features like the spindash and super-peelout new remixed/demixed music new special stages new You might be wondering, "Why did you wait so long to release a new demo?" Well, it's because I wanted to improve this as much as I can and to maybe make this more popular among the Sonic community (credit to RHS for inspiring me to do this) I think it's right to start out with the new levels, this demo adds: Bird Maze Zone Bird Bridge Zone Bird Forest Zone act 1 Bird Ruins Zone Secondly, I think it's time to highlight the character that got the most changes, Tails! While Sonic got the super peelout and Knuckles has his jump height more accurate, Tails FINALLY has his Tails and can now fly! Another thing that I have added or changed is the music, I have changed all or most of the music tracks to sound a bit different compared to the original music tracks. Another thing that has been cleaned up is the levels, now some levels have dynamic color palettes for different acts, and also Mysterious Marble Zone has it's grass color changed to Bird Hill Zone for consistency. I have also altered some level layouts to feel a little better than they used to be back in the 3rd demo. There is also 2 new special stages, the 4th one is similar to the first 3, and the 5th one which is more of a platforming challenge and was inspired by Sonic ERaZor. I have also added the options menu so you can more easily choose your character and I also added an option if you want the super transformation to be Super Sonic or Power Sonic. Some menus have been changed, like the "original game by text" now has a better font, and the Blue Gamer Presents Screen and the title screen has got a full graphic overhaul. Hope you enjoy this demo!

Mean Bean Tsuu returns for SHC2025! This demo of Mean Bean Tsuu gives a sneak preview to some of the new character roster with a three-stage demo and features a BRAND NEW randomised opponent system where each playthrough will see you battling your opponents in a different order or even different opponents entirely! With more new board designs, character artwork, and brand new cutscenes, we hope you enjoy what's to come with this Mean Bean hack. Mean Bean Tsuu is a hack which aims to be a sequel to the original game, featuring new mechanics from Puyo Puyo Tsuu, as well as a story more in line with that of Japanese Classic Sonic canon. It still follows Mean Bean's original mechanics, though research is being done to get those Tsuu mechanics in! The new features in this year's demo include: Restored Lesson Mode Stages 5 Stage Boards - 2 returning from last year New Arrangement of the Main Menu music by Aburtos 8 New Characters (including a returning Coconuts) Random Opponent System for Scenario Mode (2 stages featuring more friendly characters, and a final stage against one of Robotnik's goons) New backdrop for cutscenes New Title Screen and Game Over Screen

What is Sonic at its core? A game about jumping and running. So why not create a Sonic hack where you do nothing but jumping and running... for 8 hours straight? The concept and inspiration were obviously taken from the infamous Desert Bus minigame from Penn & Teller's Smoke and Mirrors. Also, a special shout-out to the annual charity event Desert Bus For Hope, which gave me the motivation to even create this hack. (There's also a mode that compresses the experience down to 8 minutes. Still ridiculous, but it's a nice meditation exercise.)

Debut Sonic in Giovanni's Level Pack 2 is a ROM hack of last year's Giovanni's Level Pack 2. This ROM hack was originally made by MDTravis, to be later picked up and polished by giovanni.gen, original creator of Giovanni's Level Pack 2. In this ROM Hack, you will play as MDTravis' implementation of Sonic, as seen in Sonic Debut, the latest available version of which, at the time of writing, can be found here. The original version of the ROM hack was unveiled during a Sonic Hacking Contest live stream, as a prank directed to giovanni.gen. This release is the polished version of the ROM hack shown during said live stream, featuring many QoL changes to better account for Debut Sonic, such as a proper HP display, and a fully rewritten instruction manual. The catch, however, is that almost no changes have been made to the level design to account for Debut Sonic's altered moveset. Debut Sonic in GLP2 has been playtested, and is 100%able. However, it is not softlock-proof, and some routes from the original game are flat out inaccessible. To beat Debut Sonic in GLP2, you will have to contend with a slightly lowered jump height, lowered just enough to make damage boosting mandatory for basic progression in places. In addition, none of the additional moves from the original ROM hack have made the cut: no Drop Dash, no Super Peel-Out, and, most critically, no Spin Dash. Debut Sonic's moveset includes an Air Roll, which you will need to use, as you will not automatically roll after jumping like Sonic would. In addition, as opposed to losing rings when damaged, you will instead be bound by a HP system. Starting at 5 hit points, losing them all will result in your death, no matter your ring count. This ROM hack is best experienced after having played both the original Giovanni's Level Pack 2, and Sonic Debut, with much focus on the former. Changes from last year: The player controller was completely changed, in terms of graphics and moveset; The shield monitor was fittingly replaced with a HP boost monitor; Certain sound effects originating from Sonic Debut have been added; A HP meter has been added to the HUD; MDTravis' Splash screen has been imported into the hack; A minor, optional change to the level design in Marble Zone was made; The instructions manual was majorly rewritten.

Created in just 12 days for Halloween 2024, this short ROM hack is all about how much of an eerie atmosphere can be achieved in Sonic 1 by removal alone.

Every action carries an immediate, permanent consequence. Collecting a ring, defeating an enemy, finishing a level—each choice causes something in the game to vanish forever. The more Sonic interacts with his surroundings, the emptier the world becomes, leaving him to wander through a silent, desolate landscape. There are no jumpscares, no hyper-realistic blood, and definitely no Sonic.exe—just a quiet, decaying world. Will you keep moving forward, even as everything around you fades into meaninglessness? Or will you look for an escape?

P.S.: Inspired by Spindαsh in Sonic 2 SMS and Half-Life 2: Alone Mod. Also, I would've loved to call this hack Sonic Eraser, but unfortunately that name is already taken. At least it served as a nice palette cleanser after working on Sonic ERaZor 7 for ten months, heh.

Sonic the Hedgehog: Isle of Magnetic Artifacts is a sonic hack made By Neo Team Kyukyoku

is a hack which aims to overhaul Sonic 1 using a Japanese-inspired aesthetic. The main feature of this demo is Blossom Gardens Zone, the resting area of the isolated, star-god worshipping Kuratranos tribe. BGZ is a fast-paced experience littered with swift-acting enemies, height-granting gimmicks, driving music, and advanced graphical effects. This new zone can be traversed with three playable characters: Sonic the Hedgehog, Miles "Tails" Prower, and Knuckles the Echidna. Sonic, in particular, features a set of unique sprites, the dropdash ability, and a new companion: Abbey the Flicky. Abbey can pick up nearby rings and circle potential targets for Sonic, including hidden monitors.

Sonic 1 Flash Flood is a ROM hack of Sonic the Hedghog that features new palette, audio, zone layout and special stage modifications, in addition to new gameplay mechanics. Flood waters rise and recede at random all over the island, significantly changing how the island is navigated. Can you make it through?

Features:

• Level Design - In addition to the rain effect and water palettes, level layouts are tweaked to account for water physics.
  • Marble Zone has altered lava physics, and Acts 2 and 3 have new shortcuts.
  • Being entirely underground, Labyrinth Zone has been affected a bit...differently by the change in weather.

• Goggles Monitors - These take the place of air bubbles, and are thus unlimited. Use as many as you need!

• Badnik Behavior - The rain and flooding is even affecting Eggman's robots and hazards, causing them to malfunction! Some are even enhanced by the chaotic weather. Strangely, most fire-related hazards (such as flamethrowers and fireballs) remain unaffected, defying all logic.

• Special Stages - New special stage gameplay style, with art and music changes. Get Yellow Rings!

• Water Physics - Some general quality of life improvements to the water physics, and bug fixes are included here (with a few exceptions, for gameplay reasons).

• Level Select - Available upon pressing start, no code required. Feel free to check out any zone or special stage at your leisure.

Known Bugs:

• Minor graphical bug in the special stage background, and on the results screen.
• In the Special Stages, blocks at the edge of the screen being loaded in flicker, due to the amount of objects.
• Level art mapping glitches crop up on rare occasion.
• Labyrinth and Scrap Brain's palette cycles are bit buggy at the moment.
• There are a couple of lingering walk-jump bugs here and there

Planned Features

• Improved object optimization
• Importing Sonic 2-3's child sprite system
• Underwater sound/music mode
• Even more environmental effects.
• More significant changes to bosses, Final Boss, etc.

Sonic ReOne is a hack created by DeltaWooloo which takes Sonic back to where he originally started 29 years ago in South Island. This hack features new palettes that cycle through every act just from bright morning to dark evenings. Iconic features from classic Sonic games arrived in this hack (see the features below) Eggman pumped up his bosses to make it harder when you annoy him by hitting him. The level design is a mix between linear and platforming which is something you see in Sonic games, but be careful that you don't go too fast. Eggman placed badniks and springs to prevent you from going to the end. The music is catchy and fun to listen to and suits the mood of the zones.

This hack features art and music edits, new level gimmicks, and boss edits. Since 2015 I released a new build each year for Halloween. This however will be the last yearly build. While there are still changes and improvements that can be made, I am ready to move on with other projects.

Since the last time this was entered into the contest I have made more changes to the art, updated some of the music, added new level gimmicks, adjusted a couple of the bosses, and fixed several bugs.
