Sonic 3 A.I.R.

Sonic 3 AIR for iOS and Web (Public Beta 2021.09.28)

This is a beta release. The port is not finished yet. You will encounter problems. Here are just a few notes before you start:

Once the game has been installed to your home screen, there is a one time data download of around 8MB when you launch the game for the first time. If your device goes to sleep during this, the download will fail and you will need to kill the app and relaunch it for the download to try again. When a new version of the game comes out, you will need to download the entire thing again just like you would with the PC versions.

There is a basic file manager accessible when you select "Exit" from the main menu in game. This will allow you to upload or files from the save data folder. Currently you need to upload files one at a time, but mods inside .zip files are supported to make uploading mods easier. The primary use for the file manager right now is if you want to backup your save data or upload your save data from the PC version.

The remastered soundtrack is not included by default in the iOS / Web release. Due to limitations of running the game as a web application, all content must fit into memory. Not including the remsstered soundtrack saves over 100MB against the size of the game, making it run more stable on many devices. There is now an "Extra Downloads" button above the file manager, which can be used to download the remastered soundtrack. You can also manually upload audioremaster.bin from the 2021.09.28 PC release into the file manager manually if you have issues downloading it from the server. If the game is unstable after doing this, you can delete autoremaster.bin via the file manager to improve game performance.

A To Do list for the iOS port with more details on known issues and changes that are planned for later can be found here.

iOS Requirements

The iOS version requires a device running iOS 13 or later. Following these steps on an older device will not install as intended. You may be able to play in Safari using the web browser link instead.

How to Install

Tap the Share button

in the Safari toolbar.

Select "Add to Home Screen" from the options that appear.

Once the initial data download is complete, you will be prompted to select your Sonic_Knuckles_wSonic3.bin game file. This will be copied into your save data folder so you will not need to select it again later.
