The Adventures of Quik & Silva is a platform video game originally released in 1991 for the Amiga and Atari ST. The game was developed by members of Factor 5 pseudonymously as New Bits On The RAM (presumably a play on New Kids on the Block), and was first published as a covermounted disk on Amiga Fun magazine. The game was later available in 1992 as public domain software, with the Amiga version reviewed in issue 18 of Amiga Power. This game is assumed to be the first appearance, albeit unlicensed, of Sonic the Hedgehog for a home games format. Additionally, the various enemies in the game are based on characters from other titles, such as Bubble Bobble, Nebulus, R-Type, and The Great Giana Sisters.
