Sonic & Knuckles Collection
From Sonic Retro
Sonic & Knuckles Collection is a compilation for Microsoft Windows based PCs, released in 1997. Games included are Sonic the Hedgehog 3, Sonic & Knuckles, Sonic 3 & Knuckles, and Blue Sphere (listed as "Special Stage Mode").
This game is virtually impossible to play in windowed mode on any system with a CPU faster than 350MHz (without any patches), because it lacks a speed-limiting feature in this mode. However, the timings used by full screen mode are based on the monitor's refresh rate, so the game can be played at the correct speed at a 60Hz refresh rate on any modern system. The framerate in windowed mode can be corrected by setting a value in the S3K.ini configuration file, described here.
Differences from console version
Most of the original music is emulated, with the user able to choose between MIDI and FM formats. Furthermore, some of Sonic 3's music tracks, including those of Carnival Night Zone, Ice Cap Zone, Launch Base Zone, Knuckles' theme, the Competition menu, and the credits music, were replaced with original compositions. One possible explanation for this is that the tracks featured sampled sound effects not supported by the MIDI standard, and some sound cards during this time were not capable of playing these alongside the standard MIDI instruments. Another potential explanation is that the original tracks may have been composed by Michael Jackson, and were removed due to legal reasons that arose since their original release. Aside from this musical difference, the game plays virtually identically to its original incarnations.
Other differences include the fact that the Sonic 3 & Knuckles Level Select Cheat works on Sonic 3 alone, in Angel Island Zone. This code (usually input at Mushroom Hill Zone in Sonic & Knuckles) does not enable debug mode as in the original, though it does still allow characters to play stages they couldn't access otherwise from the level select. Examples include Tails in Doomsday Zone and Knuckles in Sky Sanctuary 1. When the level select code is performed in Sonic 3, and the first special stage option is selected (which unlike in the original accesses the blue sphere mini-game), this enables the player to use Knuckles in the Sonic 3 levels, though they are incomplete and thus cannot always be beaten.
Sonic the Screen Saver
In the US and in Europe, "Sonic the Screen Saver" was included in the compilation. This disc allowed users to customize Windows with Sonic themes, wallpapers, icons, and play music from Sonic 1, 2, 3, S&K and the Japanese version of Sonic CD. In Japan, Sonic the Screen Saver was sold separately.
