Sonic the Hedgehog 2 for the Sega Master System was released in 1992, developed by Aspect as a separate 8-bit version of the hit sequel rather than a port of the Genesis game. Players collected Chaos Emeralds hidden in special stages to unlock the best ending. The short found emerald jingle, credited to Masafumi Ogata, became a familiar reward cue for a generation of players. Clips of the sound now circulate on soundboards and in edits, reused whenever creators want an unmistakable retro signal for finding something valuable.
