Via Hacking the Sonic 3 ROM, fans have found artwork showing Sonic on a surf board. The story goes that it seamed the Original intro was going to be Sonic riding to the Island on a Surfboard. There he carries on with the level. The First Meeting with Knuckles thus happens at the end of the first level. It is unknown how much of this is true but it appears to be the case from a couple of beta Screenshots. A Fan hack has restored this original opening to as close as possible at this time. ScreenShot is from 'Hack' Restored intro.
Due to time and the Amount of space on a ROM Cart, It was not possible to place all of Sonic 3 on to the cartage. A Quick job was done to remove some of the levels and reintroduce them (in a different order) as 'Sonic 3 Part Two', or 'Sonic And Knuckles' as it became known. A Number of changes were done for the SnK version (including featuring Knuckles as Playable) but the Original Level order can be found via the Sonic 3 Level Selection. It shows off a Sonic 2 Style level selection, showing it is in fact the Sonic 2 Engine, and even has the place holder Art work from Sonic 2 (Including 'Deleted' levels) It appears this was never meant to be an gamer cheat but a debug tool, thus the appearance of the Special zones and Bonus games. Using this Order, it is pretty easy to see how the levels would tie in. The cannon blast at the end of Carnival Night would throw you up to the Flying Battery, you will fall from that into the IceCap zone etc.. It is a bit Unclear as to Launch base onwards but it would appear that Sonic would have a chance to finish off Robotnik After stopping his Death Egg.
An Image printed in STC shows the Snowboarding Intro for Ice Cap Act 1 BUT without the Snowboard. Sonic is just running down the hill. I would guess that this is linked to the early level setup Or maybe the removed intro. Maybe after removing the surfing intro, the team really wanted to stick something of it in, and did so with ice cap? doubt it... but possible.
A number of early 'beta' Sonic 3 images were printed in STC at different times. Most of them don't have much of interest (other then the Running down the hill) but this one is a bit more then the others. As you can see from this and the above, Sonic was still using the Sonic 2 Sprite. This isn't anything new, the thing that singles this image out is that the slope is all wrong. This is clearly near the start of the level (first RhinoBot) and on the Retail version of the game, the bottom bit of the slope isn't there (it slopes just under tails tail and goes flat). Tails also (by the way) is the Sonic 2 Sprite
It Seams Sonic was very busy in 1993. An article printed in STC issue 5 talks about the large number of Sonic related stuff on it's way. Not only is Sonic Spinball, 'CD Sonic' (later known as Sonic CD and two more games there are two new pals for Sonic. His girlfriend Amy Rose and.... Ray? An Early issue said bout Sonic's Arcade game which stars him and his new pal Ray (no word about Mighty at that time) but it appears that Ray is going to return in Sonic 3! But Tails will still be around (though probably not for that game)... In a way, the lettering of the Article gives the impression that maybe he was planned but mostly seams to be saying there are new characters (and a Tails replacement) in the game.. it turned out only to be Knuckles. They say it's only a rumour and it's unknown how far this rumour went. Maybe there were plans to have Ray in the game, but it is pretty doubtful. So we have to make do with my mock-up image.. Ray Sprite by Manic Man.
The Ladybird released puzzle book 'Where's Sonic Now' features a few things that might be removed features, since most of the time these books are made with stuff given from the company themselves. It is only about 25% trustworthy but still. The first two 'puzzle pages' are Angel Island Zone 1 and 2 (Act 1 and 2 that should be) and are fairly right to the level apart from two details. The first is more Water really and the other is a badnik that looks a lot like Sonic 2's Chopper. Now, it is possible (and maybe likely) that a Chopper was planed for that level but it was felt it didn't really go well thus was removed. This is fairly likely and has happened in the past. Sonic 2 was to feature the Snail bot (an Upgrade from the Motobug) but it was removed. It DID, however feature things like the Grounder that was an upgrade from the Burrow Bot, so it's possible that there was an idea to do a Chopper based Badnik in this game but removed it.
If you look at the Knuckles Sprite from Sonic 3 when he is an Enemy and compare it to when he is playable you notice something. As pictured, when you compare the sprites, you notice Knuckles 'rims' on his Sneakers are in fact Yellow in the original and Green in the Final one. This seams to be a quick mistake as if you notice the final one still has one spot of Yellow where it wasn't changed fully. Never really a big mystery but for anyone that wondered about that spot, here is the answer. For Some reason, Knuckles shade was also changed from Pink to Red. Though this appears to have been done pretty early on, the Enemy version of Knuckles still has this problem in the final version.
