Welcome to the Sonic Archive of Roms, or SonAR! It's a terrible acronym, I know, so please don't yell at me.
This is a page created for the purpose of archiving and documenting every official, scene, and community recognized Sonic the Hedgehog related cartridge backup (ROM) available.
SonAR is absolutely NOT a scavenger hunt/rodeo roundup of every rom in existence. Rather, it's a library. A record of every cartridge backup of the Sonic persuation.
Please note that disc images are not necessarily going to be hosted here, as they take up far too much bandwidth, and the ones that happen to be here will not take priority over cartridge backups.
