But the freakiest thing that was in that split second frame was Sonic, his eyes were pitch black and bleeding with two glowing red dots staring RIGHT AT ME, and his smile had stretched wider up to the edge of his face. I was rather disturbed about that image when I saw it, though I figured that it was just a glitch and forgot about it. After it cut to black it stayed like that for about 10 seconds or so. And then another weird thing happened, the save file select from Sonic the Hedgehog 3 popped up, and I was like "WTF? What's this doing in the first Sonic game?", anyway, then I notice something off, the background was the dark cloudy sky of the Bad Stardust Speedway level from Sonic CD, and there were only three save files. The music was that creepy Caverns of Winter music from Earthbound, only it was extended and seemed to have been in reverse. And the image for the save file where you see a preview of the level you're on is just red static for all three files. What freaked me out more was the character select, it showed only Tails, Knuckles and to my surprise, Dr. Robotnik! Now I was sure that something was up, I mean, how can you play as Robotnik in a classic Sonic game, for crying out loud? 
That's when I realized that this wasn't a glitchy game, it was a hacked game. 
Yeah it definitely looked hacked, it was really creepy, but as a smart gamer, I wasn't scared (or at least I tried not to be), I told myself that it was just a hacked game and there's nothing wrong with that. Anyways, shaking off the creeped out feeling I picked File 1 and chose Tails and when I selected and got started. The game froze for about 5 seconds and I heard a creepy pixelated laugh that sounded an awful lot like that Kefka guy from Final Fantasy before cutting to black. The screen stayed black for about 10 seconds or more, then it showed the typical level title thing, except the simplistic shapes were different shades of red and the text showed only "HILL, ACT 1". The screen faded in and the level title vanished revealing Tails in the Green Hill Zone from Sonic 1, the music was different though, it sounded like a peaceful melody in reverse. Anyway I started playing and had Tails start running like you would in any of the classic Sonic games, what was odd was that as Tails was running along the level there was nothing but flat ground and a few trees for 5 minutes, that was when the peaceful music started to lower down into slow deep tones very slowly as I kept going. I suddenly saw something and I stopped to see what it was; it was one of the small animals lying dead on the ground bleeding (That was when the music started to slow down), Tails had a shocked and saddened look on his face that I never saw him have before, so I had him move along, and he kept that worried look on his face. As he kept moving I saw more dead animals as Tails moved past them looking more and more worried as the music lowers and he moves past more dead animals, I was shocked to see how they all died, they looked like somebody killed them in rather gruesome ways; a squirrel was hanged on a tree with what appeared to be his entrails hanging out, a bunny had all four of his limbs torn off and a duck had his eyes gouged out and his throat slit. I felt sick to my stomach when I saw this massacre and apparently so did Tails. After a few more seconds there were no more animals and the music seemed to have stopped, I still kept Tails to continue.
