The first known mod ever made for the Android port of Sonic Jump's AirPlay version is named "Sonic Jump 2" by GdGohan.
This mod has a different title screen and the music tracks all uses instruments found in Sonic games on the SEGA Mega Drive/Genesis. GdGohan used an app named MIDI Clef to change the soundfont of the .midi soundtrack.
The most interesting change about this mod is that the PuyoSega service condition is bypassed, making the game playable instead of being locked behind an error message.
Furrican discovered the Android port of the Sonic Jump's AirPlay version back in early 2022. However, he couldn't find the original .apk file at the time and instead found the GdGohan's mod.
And when Furrican managed to find the original .apk file of the game, he realized that the game didn't work, due to the PuyoSega service condition which prevents players to play the game. As the result, he transferred the source code from the GdGohan's mod to the original game to work on his first mods.
The Sonic Jump Classic mods was released on Game Jolt and itch.io.
The Classic mods were a pack of .apk files. Each .apk file contains a different language. The presented languages were the 6 lanugages from the original AirPlay version, alongside the Japanese language from the original Android port.
The version 1.1.0 was released immediately. This update allows players to press anywhere on the screen to perform the double jump, instead of pressing on the "Select icon" (only when VIRTUAL PAD: OFF).
BEGINNING:
At the same day as the mods released, a Game Jolt user named Dark GUI (formerly known as GuilhermeSonic) contacted Furrican about the Portuguese language not being the Brazilian one.
Therefore, Furrican sent the text to him and he worked on the Brazilian Portuguese translation.
While the translation was done just 2 days later, the text implementation took so much time, due to the text being stored in .dat files and other external reasons.
SEPTEMBER 7th 2022:
The Brazilian Portuguese language has been added to the mods pack.
On January 2025, Furrican wanted to celebrate Sonic Jump's 20th anniversary by releasing a major update to his Sonic Jump Classic. The update was named Sonic Jump Anniversary.
Sonic Jump Anniversary was originally going to be a simple update to bring the Language Select menu and fix the stage crash found on Android 8.0 and higher. However, a collaboration changed the course of this update, making Sonic Jump Anniversary more ambitious than it was originally planned.
Furrican already met GdGohan and asked him to work on Sonic Android mods. GdGohan agreed to help working on the Sonic Jump Anniversary project.
Furrican's plan was to release Sonic Jump Anniversary for the Sonic Amateur Game Expo (SAGE) 2025. However, GdGohan had way more ideas for this project by adding brand-new gameplay elements and other features. Because of GdGohan's ambitious ideas, Furrican decided to change plans for Sonic Jump Anniversary by releasing it for the Sonic Hacking Contest (SHC) 2025 instead. So they decided to release a game demo while they are working on the full version for later.
During the multiple months of developments, GdGohan often came up with new features for Sonic Jump Anniversary, some more interesting than others. However, some of his ideas were either too complicated or too out-of-place to be feasible, but compromises can sometimes be found. Additionally, GdGohan published videos of the Sonic Jump Anniversary mod development to his YouTube channel.
From February to July are multiple users who wanted early-access to Sonic Jump Anniversary. While the game was still under development, they still had early-access builds.
Some are beta testers like Sonic Blast, Star and ZueMods, others like Silas the sonic fan, Theusx games and Classic Sonic The Hedgehog were uploading their gameplay footages on YouTube.
Exactly 20 years after the very-first version of Sonic Jump, the Sonic Jump Anniversary Demo was released. This demo introduced the new planned features (language select and stage crash), but also Shadow the Hedgehog as a brand-new playable character. Additionally, the Anniversary demo introduces a secret character only unlockable via the cheat code.
The Anniversary Demo introduced a brand-new animated introduction for the loading screen. This introduction is based on the China Mobile version of Sonic Jump.
Being a demo, the stage select and cutscenes aren't present, and there is a 5-minute time limit. When the time runs out, you are brought back to the main menu.
Alongside the Anniversary Demo was an update to the Classic mods (v1.2.0). This update allows the Classic mods to get rid of the stage crash. However, this update was a limited edition and was only available until the full version of Sonic Jump Anniversary was released.
The Anniversary Demo received an update by adding 2 diagonal arrow buttons above the main ones when the VIRTUAL PAD is ON. Those arrow buttons are taken inspiration from Pleasant Goat Jump, a Chinese-exclusive mobile game similar to Sonic Jump. The diagonal arrow buttons was suggested by a Chinese user named 任索嘉盒Ninesogabox, who was inspired by Pleasant Goat Jump.
The diagonal arrow buttons act as a combination between moving left or right and perofrming the double jump at the same time.
However, while these diagonal arrows were removed from the full version of Sonic Jump Anniversary (due to those arrows being distracting), their commands are still present.
Somewhere on June 2025, Furrican has made maps of the first 3 zones of Sonic Jump, because nobody has done it at the time. Those maps served as a basis for another GdGohan's idea.
In that same month, GdGohan managed to make a Map Editor application for Sonic Jump Anniversary. He first converted the map.bin file into a .txt file, giving the maps logic better understanding.However, after looking at some maps, both Furrican and GdGohan found out that the Y-position of objects located in maps are in 8-bit values. This is problematic, as the objects may have higher locations than 255. Therefore, GdGohan found a compromise by making the Y-position values into 16-bit for .txt files.
The Map Editor has received updates over time, improving the object presentation and user interface. It also received new options such as music options and extra configurations.
The Map Editor was originally a separate application of the game. However, GdGohan later put the Map Editor in the game by making it accessible from the main menu.
October 4th 2025 was the public-release of the SHC 2025, alongside the full version of Sonic Jump Anniversary. This update has 2 versions: a regular version and a SHC edition. The source code of the SHC version is also available to download via the SONIC HACKING CONTEST link down-below.
Because of the long mod development, Sonic Jump Anniversary introduces a lot of features. The new features include the Map Editor, Game Events, Internet functionalities, and more (mentioned down-below)...
GdGohan first added an option to change the virtual pad style to make it resemble the one from the 360x640 version of Sonic Jump. Then, he added an option to add CRT filter effects to the screen to give the game a more nostalgic flair. The sprites and fonts options came afterwards to resemble the AirPlay version of Sonic Jump found on J2ME phones.
In the Sonic Jump Anniversary trailer, you can see the options menu being different from the full version. Also, the J2ME option for the PAD STYLE used to be named S40 (in reference to the Nokia S40, the phone used to run the 360x640 version of Sonic Jump).
While Furrican was first thinking about locking these options behind the cheat code, it was finally decided to put these options in a sub-menu named GRAPHIC STYLES.
In the SHC version, the J2ME fonts were the default fonts to showcase both Furrican and GdGohan's modding capabilities.
The Multiplayer game mode was meant to be available from the start, but due to its poor implementation, it was decided to lock it behind the cheat code.
In fact, Shadow the Hedgehog was originally planned to simply be the second player for the Multiplayer game mode. However, due to the unfortunate decision for the this game mode, another thing has to be done for Shadow as a playable character.
Thankfully, GdGohan gave an interesting feature to Shadow by making his movement physics different to Sonic's.
GdGohan also had an idea to make a Shadow story, based on the story from Sonic X Shadow Generations. This story is available from the new story select menu.
However, because the Shadow story was unfinished, due to time constraints, Furrican wanted to lock the story select menu behind the cheat code. But GdGohan wasn't pelased about the idea. Ultimately, the story select menu was available from the start in the SHC version to showcase their modding capabilities.
While Sonic Jump Anniversary didn't have a good reception among the judges, it did received 2 trophies.
The Spinball Trophy for being the most unusual game to be modded, and the Chao Garden Trophy for having the most potential replayability.
