To clarify, is the essential ROM file required to run Sonic 3 A.I.R. (Angel Island Revisited)
: Widescreen support, 60 FPS, bug fixes, and a mod manager.
Sonic & Knuckles alone gives you Mushroom Hill, Flying Battery, Sandopolis, Lava Reef, Hidden Palace, Sky Sanctuary, and Death Egg. That’s seven great zones. But you start in media res —Sonic is already chasing Eggman, and Knuckles is already being tricked. You miss the Death Egg crashing at Angel Island. You miss the opening cinematic of Sonic tumbling out of the Tornado.
: Unlike separate ROMs for Sonic 3 and Sonic & Knuckles , this .bin file contains the complete "Locked-On" experience in one package [6].
