Sonic and Knuckles Collection (Sega, 1997)

The PC port of Sonic 3 and Sonic and Knuckles, released by Sega in 1997. This torrent is built from the US reissue by Expert Software in 2000, but is identical to the original aside from including a PDF version of the manual on-disc. This is an actual Win32/DirectX port of the game, not a Genesis ROM running on an emulator.

To get this running on a modern computer, create a file called C:\Windows\S3K.ini with the following contents:

[Debug]
EnableFrameDrop=1
MukaiDropFrame=0
CDCheckEnable=0
