Proto:Sonic Adventure (Dreamcast)/AutoDemo/Stage Differences/Emerald Coast

This is a sub-page of Proto:Sonic Adventure (Dreamcast)/AutoDemo/Stage Differences.

Emerald Coast has a sizeable amount of changes from the final game and is very incomplete - the lighting is very dull compared to the final, many decorative objects including rails and chairs are missing, and the level lacks death planes. There is no music in the first two Acts, nor do any Act transitions exist.

Act 1

• Sonic starts in midair directly above his normal starting point. When he lands, the camera angle is different:

Proto	Final

• There are no item boxes behind the starting point.
• Two Rhinotanks near the bridge instead of one.
• Only four springs crossing under the bridge at the beginning instead of five. Some are also floating without supports.
• No rope barriers on the platforms after the springs. No swinging spike ball in the middle of the area after the springs, either. There's also only one spring used to get Sonic back up to the bridge before the loop; in the final, there's two.
• The first loop only has one dash pad. It also has a very different camera angle than the one in the final:

Proto	Final

• There are extra Rhinotanks before the jump ramp.
• No item box around the back of the island with the jump ramp.
• There is a Kiki instead of a checkpoint after the jump ramp.
• There are extra dash panels present in the small area Sonic runs through after the jump ramp.
• The checkpoint before the whale chase is placed right after the second loop, rather than just before the chase itself.
• The whale and its chase section is completely missing.
• No Kiki in a tree next to the second spike wall.
• Three "?"-ring boxes are missing behind the large island near the lighthouse.
• There is an extra spring added while climbing the large island.
• There are fewer floating islands around the 1-Up box near the end of the Act than in the final.
• You don't get picked up by wind if you fall down one of the holes around the lighthouse.
• There are Kikis on the rails near the lighthouse.
• There is no Kiki above the Act transition point.

Act 2

Act 2 is missing most of the objects throughout the level. Notably, the latter parts of the stage are almost completely empty.

• There is an extra set of rings after the first checkpoint that doesn't appear in the final.
• The last two checkpoints are missing.
• The ring layout on the wall near the start is very different. Only small single lines lower down. There is no Speed Shoes box on this wall, either.
• No objects in the higher tunnel accessed from the wall.
• Springs at the upper path do not work correctly consistently and have a different spring path.
• No 1-Up box or dash panel after the springs in the upper path - only rings.
• Rings entering the water in the lower path are in midair.
• The Sweeps are at the bottom of the pool rather than on the surface. There are also 3 of them, with the final reducing this to 2. There are also no air bubbles or platforms in the water:

Proto	Final

• No circle of rings after the pool.
• No ring box in the spike wall area.
• There is a 10-ring box after the spike walls that has been replaced by a Kiki in the final.
• Very few rings before the big loop.
• No dash panel after the big loop.
• Jump ramp does not work correctly, you hit the invisible wall at the edge of the land.
• The area with the large steps in the final lacks the objects, so it's a smooth hill. This can still be seen in the final from a distance, though.
• There is a Kiki on a small tree in the step area that is not there in the final.
• The camera in the tunnels going up to the checkpoint area snaps to locations instead of gradually travelling to them.
• No dash panels in the large hill after the checkpoint.
• The jump panels are the only object present in the area they're found in. The boxes, Kikis, and hint orbs are missing.

Proto	Final

• There is no spring after the jump panel area to get into the area with the third panel in the final.
• The alternative route to the jump panels (spring) does not work. The spring sends you to your death.
• Jump panel order is different. The final's second panel is not there, meaning there's only 4 panels.
• The last panel is slightly to the right of the platform you're going to, rather than directly above it. There are also no spike walls present.
• The automated path for the last loop is absent.
• The end island is completely empty.

Act 3

• Big spawns on the island in the secret cave area, rather than his usual starting point on the beach.
• There is a light effect over the island that is not in the final.
• There are no fish, the only thing available to catch is Froggy.
• The exit to the cave has been blocked off.
• The game will crash if Big goes up the slope where Sonic's first spring is/his 1-Up box is in the final.
• A 1-Up box from Sonic's version of this level is still present.
• Objects from the Sonic version of this stage (the objects before the loop) still exist and seem to be from later along than Sonic's acts - the rope rails exist, there is a lot more decor, the missing springs are present, etc.
• Froggy is very weak and it's impossible to break Big's lure even if his reel gauge reaches its limit.
