Donkey Kong 64 is a 1999 platform game for the Nintendo 64, developed by Rare and published by Nintendo, in which the Kongs use projectile weapons to hit switches and enemies. The aim alert is one of its short in-game feedback sounds, signalling that a shot is lined up during aiming. As clips from the game circulated in retro gaming videos and meme edits, the brief tone became a handy shorthand for locking on to anything, from a rival in a game to an everyday object. Its Nintendo 64 sound and short length keep it recognisable and easy to reuse.
