Odd object placement and background differences!!

Some enemies have even been turned into spikes!

Sonic 3 was split for a couple reasons

1. To get it out quickly (hence, Sonic 3 is rather buggy)
2. To get us to pay more money for it

 

I said Act 2 of Lava Reef. And I said it was gone in Sonic and Tails' game play too in Sonic Jam which is sad, since if it hadn't been gone, it would have been the perfect S&K game version. It should have been! It's Sonic Jam I'm talking about here

 

I know, I was being sarcastic :P

 

I think that the EggRobo isn't used for any programming reasons, like a change in palette or something like that. I think it has to do with the storyline. Remember that Robotnik was trying to get Knuckles to trust him. So why would Robotnik attack someone who was supposed to be his ally? Instead, Robotnik sends something else out to keep Knuckles from getting suspicious, and that 'something' is the EggRobo.

P.S.--Sometimes I wonder why things like 'EggRobo' that say 'Egg' in them aren't changed to something more Robotnik-oriented in America. Then I realize that 'RoboRobo' just doesn't roll off the tongue as easily.

 

Sort of what I said earlier. The best theory so far on this is that Dr. Robotnick has gone AWOL after having his arse kicked in Doomsday Zone, so MechaSonic decides to stir up trouble by getting Eggrobo to get the Master Emerald back for him, so he can exact his revenge atop Sky Sanctuary.

... or they overlooked that sprite (and if they overlooked it, then they probably over looked the VDP programming for Robotnick fleeing in that zone too.)

@ L0st: Out of intrest, playing as Knuckles in FBZ 2, does Eggrobo or Robonick turn up piloting the boss in Sonic Jam?

 

Actually, if you see the very end of the credits of Sonic's good ending in Sonic & Knuckles (alone) I think you will see Robotnik get a mask, possibly from the badnick that looks like him, stuck on his head. It IS robotnik, just in mask. (I THINK, I could be wrong you know)

 

I always thought that Knuckles' story took place before Sonic's, thus the temporary lack of water in LBZ and the fact that Angel Island is still in the air.
Then again, that could also be interpreted as Angel Island being back in the air.
Is there any possible way to figure out for sure which story takes place first, like a guide or book or something?

 

A bit of a sign of things to come...

I know, but if they could make differences in the AIZ1 BG, why not in the LRZ1 BG? (I suppose it would be harder to edit this one tile rather than remove the islands because of how it fits the tiles, though. It's too bad.)
Is the Death Egg there in the HPZ BG as Sonic in Sonic Jam? I knew that one was changed in the original as Knuckles.

Most likely. It's a different sprite from all of the other sprites used for the S3 bosses. I think that's why it's different. The Robotnik art for this boss is part of auxiliary data for the boss (not Robotnik and the main "egg-o-matic" ship, a separate file) which was not replaced by a separate compressed art file or different mappings for Knuckles, like the main Robotnik data. They forgot to take this special case into account, or load the Eggrobo head over the special one.

But the ghosts in Sandopolis are there at the start...

...and the demolished building is not.

No, I think this is supposed to be an Eggrobo. Anyway, it's meant to lead into Knuckles storyline (people will probably play as Sonic first, and it's the default choice). I just wish they could have kept the Knuckles S&K intro with the AIZ tiles in Sonic 3.
Say, does anybody know if the game set Knuckles as the default selection at the intro after getting Sonic's good ending? (As in, you played through as Sonic, so here's a new challenge!)

 

Correct me if I'm wrong, but didn't most of Knuckles' LBZ take place sorta underground, where Sonic could never access. As far as I can remember you never even go near the demolished building when you play as Knuckles, so how would you know if the building was still standing or not during Knuckles' story?

The lack of water in LBZ could also account for the fact that the island is already in the air during Knuckles' story. I could be, and most probably am, wrong though.

 

They didn't make any differences in the backgrounds of either AIZ, LBZ, or LRZ. All they did was move the bg offset to not show the Death Egg. The answer is simple: No more room left in the ROM to save 2x backgrounds.

And I'm talking about the Death Egg "sprite" that is shown at the end of LRZ2. It's not part of the background since it is breaking the BG raster line (something you can't do with one background alone).

 

I think the building is the same, barring the fact that Knuckles can't access it. As for most of Knuckles' LBZ taking place underground, Act 1 is very similar to Sonic's. Only Act 2 is largely underground. The building in question is in Act 1.

 

I know, hence we have parts of the level where the Death Egg is not visible, as well as this (move left, through debug, past the Knuckles demo).

 

That's the one I'm talking about. For some reason that object got deleted in Sonic Jam. It can have been because of a wrong RAM address convertion? Anyway, I'm interested in looking into the code for that object and the Master Emerald object.
