The Philips CD-i port of Lemmings is pretty similar to the original release. However there are a few changes, most notably the brand new 2 minute long intro movie that completely changes the scene. Also, the UI is slightly tweaked and the soundtrack/SFX are of higher quality, with the soundtrack even getting slightly rerecorded with additional instruments. Unfortunately, the frame rate is incredibly, incredibly slow and choppy as well, making this a pretty undesirable port.
