It starts from that combined game rather than offering a new Sonic campaign. The broader view is part of its appeal: a familiar side-scrolling game is presented with more horizontal space, while the original ROM supplies the content. Sources: [Sonic 3 A.I.R. · project and ROM requirements](https://sonic3air.org/) ## A separate iOS and web beta Sappharad's port brings A.I.R. to iOS and WebAssembly browsers. It is explicitly a beta with less functionality than a native app. On iOS 13 or later, the documented installation uses Safari's Add to Home Screen; other devices can use the web-browser link. After the initial download, select Sonic\_Knuckles\_wSonic3.bin. The port copies it into its data folder for later launches. The main A.I.R. site explains that the formerly supported Steam purchase is no longer sold; having an old purchase and buying a new copy today are different situations. Follow its current ROM guidance rather than an outdated store instruction.

It can import a PC save, download a backup or accept mods packaged as ZIPs. Ordinary files move one at a time, so a desktop folder-copy guide does not describe this interface. The remastered soundtrack is optional and adds over 100 MB to a game whose content must fit in memory. Start without it on a constrained device. If installing additional data introduces stutter, the extra memory requirement is a relevant difference from native A.I.R.

Leave that renderer option alone even if a native troubleshooting guide suggests it. Keep the device awake during the initial download too; if sleep interrupts it, close and relaunch to retry. These are specific limitations of this web and iOS port. Sources: [Sonic 3 A.I.R. web · known issues](https://projects.sappharad.com/s3air_ios/todoList.html) ## Do I need the original game files? Supply your own compatible Sonic\_Knuckles\_wSonic3.bin. The former Steam edition is no longer sold; the official Sonic 3 A.I.R. site links information about other compatible sources. Creator-reported: [Project guide](https://sonic3air.org/) ## How do I get started? Open the web build, keep the first download awake, and select your ROM when prompted. On iOS 13 or newer, the install guide also offers Safari → Share → Add to Home Screen. Creator-reported: [Project guide](https://projects.sappharad.com/s3air_ios/20260328_beta/) ## Which devices and browsers work? The beta supports WebAssembly-capable browsers and an iOS 13+ home-screen installation path. It has web-specific stability limits. Creator-reported: [Project guide](https://projects.sappharad.com/s3air_ios/20260328_beta/) ## What is included in this version? A fan-made widescreen remaster of Sonic 3 & Knuckles. The web edition is a beta separate from native releases. Creator-reported: [Project guide](https://sonic3air.org/) ## How do saves work? The in-game Options file manager imports and exports saves and accepts ZIP mods. The selected ROM is copied into the game’s local save-data area. Creator-reported: [Project guide](https://projects.sappharad.com/s3air_ios/20260328_beta/) ## What should I know before playing? Do not switch to the software renderer: the web issues page says it can lock the game. Keep the device awake during the first download. Extra soundtrack data can cause stuttering or startup failures on low-memory devices.
