A third video of the Sonic 1 prototype has been uploaded and shows an interesting sign at the beginning of the first zone that hasn’t been included in the first two videos. Well, according to Sonicparadise.net which translated the tweets from Yuji Naka, this third video actually has several inconsistencies which lead him to believe that this is just a mod of the original game. The original prototype seems to be lost. The modder actually apologizes in another video for creating all the confusion and the mod is available for download. Hit the jump for the apology!
