Sonic 3 A.I.R. is a fan-made widescreen remaster of Sonic 3 & Knuckles. 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.
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 Follow its current ROM guidance rather than an outdated store instruction.

Options includes a basic file manager. 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.
The port's issue list warns that switching to the software renderer can lock the game. 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.
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.
