Sonic 3 A. I. R. Switch - Gamebrew

A fan-made widescreen remaster of Sonic 3 & Knuckles, made by Eukaryot and ported to the Switch by Ultracoolplayer. It includes a remastered soundtrack, mod support, and many other QoL changes.

In order to run this, you need a modded Switch, and also the Steam version of Sonic 3 & Knuckles on your PC or Mac.

Extract the contents of the ZIP to the root of your SD card.

Copy Sonic_Knuckles_wSonic3.bin to /switch/sonic3air_switch/ on your Switch's SD card. After installing the Steam version, you should be able to find it in one of the following directories:

• Windows: C:\Program Files (x86)\Steam\steamapps\common\Sega Classics\uncompressed ROMs\Sonic_Knuckles_wSonic3.bin
• macOS: ~/Library/Application Support/Steam/steamapps/common/Sega Classics/uncompressed ROMs/Sonic_Knuckles_wSonic3.bin
• Linux: ~/.steam/steam/steamapps/common/Sega Classics/uncompressed ROMs/Sonic_Knuckles_wSonic3.bin

If you want to reduce size you can delete the doc folder.

Notes: It is recommended to give the game full RAM access. This means you shouldn't launch hbmenu from the album applet when running this. With the latest Atmosphere build and its default config, you can hold R while starting any game to open hbmenu with full RAM access. If you have any issues make sure the game has full RAM access before reporting them; launching as an applet will not be supported.
