User:Porcino/Proto: Ecco 2

The Ecco II Alpha (E2A) is the oldest, most obscure Ecco prototype ever uncovered. It contained almost no levels that made it into the final game. However, it has a slew of unique levels that make for unusual gameplay. The only problem is, however, that Ecco is invincible to almost everything in the game.

Startup

This Ecco prototype shows the universe prologue and the vortex cutscenes right away, it doesn't display a Sega logo or any titlescreen or copyright information.

[I believe the ROM has been tampered with to not show them. - More on this later]

The prologue text is mostly the same as in the final version, except that "THOUGHT" is misspelled as "THOUGT". The vortex queen falling through the clouds is cut from the final version. (Data still remains there). The "meteor" cutscene uses different graphics, here it shows a background with landmasses, while the final version shows a plain ocean.

Attract mode

If the start button isn't pressed the game continues right away to 3 demos and cycles through them indefinitely.

All these demos were removed, same for the levels they take place, except the third one which is an almost finalized "tube of medusa".

Password Screen

The password screen exists in this build, but it doesn't seem to have any purpose.

The only password that seems to do *something* is "EASY...." which just plays a sound effect.

After pressing start, the game jumps directly to the:

Demo Recorder

Buttons Up/Down changes the item selection, A/B increments/decrements the item value.

First option, the Fieldnumber selects the stage, goes from -4 to 127. It would appear that negative numbers would make Ecco start in a 3D stage, but that's not the case, it just puts him on stage 0. Setting this value outside of the level range (>18) gives various results:

-4..-1: loads level 0
--regular levels--
19: Plays the victory celebration
20..77: Puts Ecco on the vortex meteor scene with purple colors
78: loads level 0
79: loads level 1
...
96: loads level 18
97..127 same as 20..77

The second option is a mode selection: 0-NORM plays the level normally, 1-DEMO locks controls but doesn't seem to do anything else, 2-REC would record the pad inputs into 0x1E0000, if it was a RAM area (possibly to be used with a development RAM cartridge), 3-PBACK doesn't seem to do anything. There are also 4 other options here: DEMO0 DEMO1 DEMO2 and DEMO3 which are the demo scripts that run in the attract mode in addition to the homebay victory celebration.

Record time is exactly what it says on the tin, after the elapsed time, the level ends and the game gets back into this screen.

Initial X/Y Pos, are the coordinates you wish to start on, -1 meaning the default level starting position. The units are in terms of blocks (128x128 pixels).

Differences

Well, let's see... EVERYTHING? Yep

The game is titled as Ecco Two or Ecco 2 in several parts of the ROM address.

Has a very different cutscene, which is not used in the final version.

Ecco is immortal but can die from lack of air only. There are a few interactive objects, most do not work. Contains many incomplete maps with characteristics similar to the final version.

Several errors of the color palette are present.

Some different enemies.

The only music in this game is that of The Lagoon stage of the game Ecco the Dolphin.

Debug Menu

To enter the Debug menu, place Ecco facing the front and press Start. Soon after the game is paused, then press the C button 8 times.

Graphics Differences

The sprite is exactly the same as its predecessor game called Ecco the Dolphin. The color palette is different in both versions.

Level Differences

3D Stages

3D Stages had different mechanics and purposes in this proto, they appear to be related to time travel, unlike the final version which they are meant for long distance travel.

The first things that are noticed is that there are 2 meters on the top left: Top one is a time remaining meter: it decreases over time and going through a ring replenishes one segment. Second meter is the regular health meter. It can be replenished by sonaring against the "eagles", which are just placeholder graphics. This is also true for the final version.

To pass the 3D stages, Ecco must cover a given distance without dieing or depleting the "time meter". Missing a ring has no detrimental effect (other than not replenishing the time), unlike the final version where missing a few makes Ecco restart the level.

There's a debug function when a 3D stage is paused that allows to configure the difficulty (makes rings float around, instead of being stationary) and change the time decrement amount. Also shows the distance from start, which is what determines the length of the level. (Can't be changed) It appears that all 3D stages end at distance = 1000, but it needs confirmation.

Buttons Up/Down changes the difficulty parameter, Left/Right changes the time decrement. This function corrupts the water tiles when called, and the text will be garbled after jumping out of the water.

Near this debugging function there are 2 others:

One that would imply the 3D stages were meant to be bonus stages(?) at some point (the function itself doesn't clear the screen, I did it manually for clarity)

Final score shows the same value as the distance from start

Enemies show the number of enemies killed in the stage, including ones struck by the hunter song

Powerups are the amount of eagles sonared (life meters gained)

Timeups are the number of rings passed.

The other function just shows "Stage: 0" (could be reading something that doesn't exist anymore)

There is no -6 MIXED in this build

-5 "3D Lines"

A level with pseudo 3D, with some obstacles. The color palette was not implemented and several glitches occur. You can take damage when touching the obstacles. Similar to level -5 in the final version.

Prototype	Final

-4 "3D Lines"

Similar to level -5, with changes in the background. In the final version the level -4 is same as the -5.

-3 "3D Shark"

Uses a strange sprite, in the final version it was changed to sharks.

Prototype	Final

-2 "3D Medusa"

This level has medusas. Similar to Level -2 of the final version.

-1 "3D Bubble"

Stages

0 "Sea of Green"

No equivalent exists on the release build. The only interesting thing about this stage is that this is where Ecco drops off his globes collected from stage 6, building the asterite.

1 "Globe Holder"

Similar to Globe Holder. Main differences are that the level art is mostly different and the fact that the globe is undestructible. It can be broken loose and damaged, but it's chains never burn off and it never chases Ecco.

For some reason, the Globe sometimes floats across the screen when the level is paused.

2 "Cutscene"

No equivalent on the final version. It's just a very long stretch of shallow water used for the first demo in attract mode. Sonaring here is disabled.

3 "Two Tides"

Is named as Third Stage and the password is: SGRQQFBB: Became Two Tides in the final version. Mostly complete. This stage came from Ecco 1 CD, where it was called Ship Grave Sea.

Comparison between the prototype and the final map. The areas in blue were removed in the final version and Red were added.

4 "Unknown"

Fouth Stage - IFKUQFBN - This evolved into Home Bay, even though it bears little resemblance. This is where Ecco starts the game.

You can find a dolphin that you'll have to follow to leave the level, into a 3D stage.

5 "Unknown"

Fifth Stage - IFKUQFBN -

To do:
More information about that level.

The level 5 contains a cutscene, which would occur when the Vortex Queen is defeated, problem is: she is undefeatable. This level is very similar to the former, if not an earlier form of it. Sonaring here is disabled, pressing A calls Ecco's friends to do some stunts. I managed to create a sonar map of it using my level viewer.

There's a beta Trellia on it which will initiate a time traveling sequence into... nowhere. Just puts Ecco back at the initial position.

Use debug coordinates X=3 and Y=12 and swim to the right, to get into the chamber. There's no way to reach it under normal means as the current is too strong to push through.

Add video

6 "Unknown"

Is named as Sixth Stage and the password is: AXTQRFBR: This level is very reminiscent of level The Eye, including some orbs and 7 closed entries with crystals.

7 "Skyway"

Is named as Seventh Stage and the password is: EBPFRFBW: Resembles Skyway or Skylands somewhat. This is one of the levels that plays music (the other is level 9), of course leftover from Ecco 1. The goal of this level is to reach the water tube as that's where the level exit is, which leads to stage 11. There is a magic arm on the right side. It works the similarly as on the final: You charge-sonar it and a part of it's tail it's released (the final has bubbles instead). If Ecco collects it, he gets 8(?) charges of the hunter song to use on the 3D stages.

8 "Unknown"

Is named as Eight Stage and the password is UZHJRFBG:

9 "Unknown"

"Untitled Level" and the password is: APHUPFBL: It is the highest level, not used, intended to be a maze. Contains 4 crystals where you can interact.

10 "Asterite's Cave"

Is named as H and the password is QNAYPFBW: Very simple form of what would be the Asterite's cave from the final version. There's nothing to do here, the asterite doesn't interact with Ecco in anyway and there's no way out of here.

11 "Tube of Medusa"

This stage is an almost finalized Tube of Medusa (on hard), main difference is that the level exit is upwards and not to the right. If Ecco falls to the bottom of the level, he will drop to level 7 from the sky.

Prototype	Final

12 "Vortex Arrived Intro"

This is the backdrop used for the vortex meteor falling into the ocean, on the final version it's a "level" called Vortex Arrived. There's nothing to do here and Ecco isn't supposed to be here anyway.

13 "Moray Abyss"

Is named as Fourth Stage and the password is IFKUQFBN: Very crude stage of what would be the Moray Abyss boss on the final. The mechanics are the same, except the side eels are much longer and will cause sprite overload and slowdown. When you defeat the shell eel, 2 globes pop out of it (like the final) and they will say this:

   Sing to the 
  shelled ones 
  and they will 
heal your wounds

Clearly just a leftover of Ecco 1. An opening will be revealed on the right side and a teleport ring will take you out.

14 "Time Machine"

Is named as H and the password is CIYMQFBQ: Prototype of Time Machine (TMACHINE). This is just a chopped area leftover from the Ecco 1 time machine stage with crazy colors. If the left dish is sonared the blocks will crush Ecco.

15 "Black Clouds"

Is named as H and the password is GMTBQFBI: This is a vortex future stage, but it plays underwater unlike the final levels which take place in the sky. This level is also a boss fight with a cyborg dolphin.

16 "Dark Sea"

Is named as O.MESSAGE O.MESSAGE O.MESSAGE and the password is: WKMFQFBT: Very crude version of Dark Sea maybe, there are a few drones than can shoot venom bubbles at Ecco or even grab him, but that's it. The level exit is on the right side to a 3D stage.

17 "Queen Vortex"

Early version of the Vortex Queen boss fight. Uses different graphics for nourishing, and she's unbeatable.

18 "Trellia's Bay"

Is named as ECCO, IF WE BREATHE AIR WHY DO WE LIVE BENEATH THE WAVES ? and the password is KGNJTFBL: It is very incomplete Trellia's Bay stage. This level has almost no object definitions and as such there's nothing in here besides the FG/BG art. There's only a bit of collision on the right side (they were probably starting to define objects at this time). Of course there are no enemies, no fish, no level exit and the water tubes are just decorative.
