Talk:Sonic the Hedgehog (Genesis)

The possible true purpose of the goggles and some other unused graphics.
In this topic on Sonic Retro, Dean Sitton answered a few questions related to early game development, among them being the original use of certain unused graphics. For example, the wrecking ball which became part of the first boss was originally used to roll into walls to shatter walls rather than Sonic's roll, and the goggles and Robotnik monitors were "warnings" rather than real gameplay mechanics. The goggle graphics would have just been automatically used underwater ala Kirby and are a red herring. He also guesses that the shrinking and "teleportation" graphics were an early death animation, and the zone icons were merely markers for that particular Special Stage. Since the monitors were empty and Sonic's roll was given an additional feature, it's easy to understand why these were removed - the Robotnik monitor was at least given use in the sequels.

The Title Labyrinth Glitch
You will be amazed at this discovery I made 3 or 4 years ago. While playing the game on an emulator, I turned on a Game Genie code that was supposed to activate Level Select without you needing to enter the code. It didn't work, so I decided to play as normal with the code still on. Later, I went back to the title screen, pressed start and POOF! Sonic dissapeared and what replaced him was some glitching and the text from the Labyrinth Zone glitch!

If someone else discovered this before me, I'm going to go CRAZY!--Fastpager200 15:08, 6 February 2013 (EST)
 * You crashed the game. Way to go. --BMF54123 15:11, 6 February 2013 (EST)
 * "and the text from the Labyrinth Zone glitch!"...? I can't think of anything that would make sense about what you're saying. Could you please elaborate? {EspyoT} 18:05, 6 February 2013 (EST)
 * He's talking about this. He just managed to crash the game and trigger an exception, nothing terribly out of the ordinary. --BMF54123 18:14, 6 February 2013 (EST)
 * Oh, I remember now. I had such a thing happen to me before on the title screen, on a real console. Probably because of how old and unstable my console is. {EspyoT} 07:55, 7 February 2013 (EST)

Unused Sprite in Sonic Eraser?
I noticed that one of the unused animations is in a sprite sheet rip for Sonic Eraser here. (Actually, Sonic's appearance in Sonic Eraser is odd in general - his eyelids are nonexistent like in the Sonic 2 Simon Wai proto and the animated series.) I don't know when and where the sprite appears since I saw a few YouTube videos didn't appear to have it. Could be something to note, and if it is used normally in Sonic Eraser.

Unused Tiles in Debug Mode
I was playing the game in Debug mode and messing around with the sprite changers and stuff. When i pass the stage as a item, i noticed the sign changed into the tiles for the goggles and "S" monitors. Also, in Marble Zone Act 2, some tiles changed into Robotnik monitor icons. It's probably due to the game loading the unused tiles. Mario Weaboo 22:40, 28 June 2013 (EDT)
 * I suppose that's how most people find these. I mean, at least 9/10 people that tried debug mode tried using it to fly past the stage towards the checkpoint, and definitely saw those. I suppose it's worthy of mentioning in the article, regardless. {EspyoT} 08:02, 29 June 2013 (EDT)

Labyrinth Game Crash
I remember seeing this in an old Youtube video, that if you spin-dash after you touch the goal sign in Labyrinth Act 3(?), you would fall down an off-screen pit and crash the game. It might be fixed in REV01, so I think it's mentionable. TheRoflGuy (talk) 15:33, 31 January 2014 (EST)
 * Spin-dash? You mean a normal spin? What happens is on act 2, if you look down (hold down) after you're past the screen, after the sign post, the game will crash. The end of Labyrinth Zone act 2 is actually filled with bugs! I'll take a look to see if any of them has been fixed for REV01. {EspyoT} 09:19, 1 February 2014 (EST)
 * Nope, I can reproduce all three glitches in REV01 as well. Nothing's been fixed. {EspyoT} 09:34, 1 February 2014 (EST)
