Sonic 4 in 1 is a compilation of Sonic 1, Sonic 2, Sonic 3, Sonic & Knuckles, and in addition allows you to also play Sonic 3 & Knuckles, Sonic 2 & Knuckles and the Blue Spheres minigame. The original idea for this came from Vladikcomper's Sonic 3 in 1. Since that hack only opted to include Sonic 1 to Sonic 3 due to limitations, I thought to make one better and prove all 4 games.Credits:Natsumi - Menu program, skeleton, game fixes, variable width font, custom Sonic Retro scripts & compatabilityFlamewing - gen\_scalers (horizontal software scaler program)GF ThePlayer - Main artistVAdaPEGA - Art help (Sonic 1, Sonic 2)ValleyBell - Sound driver helpVladikcomper - Music, SSRG splash screenMarc - Music, Sonic Retro splash screenMarkeyJester - Animationdjohe - TestingRedHotSonic - Testing
