Sonic 2 Prototypes: Lost Data
"Hey guys, let's make a bunch of steampunk artwork and jam it in the ROM on the offchance that we may use it later!"
"What good will that do?"
"Gives us something to do, and something for the guys who buy this at a vastly overinflated price in fifteen years' time to chew on!"
"Awesome. Who's in charge of putting the cryptic source code and symbol table in there?"
"That's Mike. He's kinda under the weather at the moment, don't talk to him."

Because the code is commented, we can be confident the game was indeed written in assembly language. However not an awful lot other than that can be gathered, because it is such a small section of assembly.
 Beta-M Compressed ARZ 128x128 block mappings
CODE
This data, found inside Beta-M, is uncompiled mappings for the 16x16 blocks for Aquatic Ruin Zone's layout. The data itself is very close to the actual ARZ mappings inside the rom, so it was probably only from a slightly earlier build.
The Kanji text along the top translates into "Before compression $8000 After compression $2c00 Compression ratio 34.4% Cell number 1024".

Shown here with the Chemical Plant palette (image courtesy of Mistergambit), we can see some Metropolis Zone-esque machinery, and what looks like an alternative water surface. Perhaps this was some Chemical Plant concept background art?
This appears to have been overritten with OOZ graphics in the Beta.

Left over map
Uncompressed but in unusual format

$1C324
|
Not in this build
|
This is most likely a left over from another game tested on the same cartridge, as shown to be possible with the Chiki Chiki boys data found in the Sonic 2 Beta-M below.

Hill Top Zone fireball
Nemesis Compressed
|
$A4368
|
$739C6
|
In Sonic 2 Final, this sprite is used for the Hill Top Zone boss. The Beta-M version of the sprite has an extra frame, showing this art was worked on between builds, and in Beta-M it's placeable in debug mode and functions just like in Sonic 2 final.

Hidden Palace Zone early backdrop tile
Uncompressed
|
$27098
|
$2B06A
|
This tile has been linked with the following HPZ mockup:
This tile is normally shown with the white palette, but when given the correct Hidden Palace Zone palette line, it matches up the tile in this concept art picture perfectly. It's also worth noting that in the rom it is arranged unusually; 2 blocks of 16 tiles arranged 4x4, going along from left to right and top to bottom.

Burning Log
Nemesis Compressed
|
$A44A0
|
$7436C
|
To call this a burning log may seem a little strange, since a comparison with the log bridges in Emerald Hill Zone would suggest that this is far too small, however every Palette line in the Sonic 2 Beta, when applied to this sprite, have a dark center.

Pirhana

$A835A
|
$7B4EA
|
This sprite is unused in both prototypes, and we have no screenshots or concept art which suggest what it could be used for.

Bubbler's Mother (Blinky in Nemesis' guide)
Nemesis Compressed
|
$A8F36
|
$7C0C6
|
Concept art sketches suggest that this enemy was originally intended for Chemical Plant Zone (section coming soon!)

Crocobot, Crocodile, Alligator
Nemesis Compressed
|
$A6F8A
|
$7A11A
|
Although completely inaccessable in the Sonic 2 beta, the crocobot is infact placeable in Hidden Palace Zone in the Beta-E prototype, however the sprites do not load correctly. This does show however that the Crocobot was intended for Hidden Palace, and the fact the greens are reversed could perhaps shed some light on changes that were made to Hidden Palace during it's development.

Bouncer, Crawl, Sandcrab
Nemesis Compressed
|
$A9580
|
$7C710
|
What may seem to be a Beta version of the Casino night zone bouncer, to me it seems more likely to be the "Banper" referred to in the concept art sketches. Firstly beacuse Casino night wasn't even in the game at this point, and secondly the first two frames of animation show that it was probably planned to emerge from the gound.

Trycerobot, Rhinobot
Nemesis Compressed
|
$A7B88
|
$7AD18
|
Featured in the famous Hidden Palace mockup shown above, the Trycerobot remains somewhat of an enigma. With the Hidden Palace Zone palette applied it is all green, which appears to be incorrect given the mockup.

OOZ Seahorse
Nemesis Compressed
|
$A8852
Obj51
|
$7B9E2
|
The seahorses shoot oil balls at Sonic when approached, and the object code can be found by disassembling either rom. They are even placable (though garbled) in the Beta-E prototype in Hidden Palace.

OOZ Octopus
Nemesis Compressed
|
$A7868
Obj4A
|
$7A9F8
|
Although this uses the same sprites as in the final (and is pink like in the final despite the image), this Octopus behaves differently due to different object code within the ROM. When it sees Sonic, it fires a glowing bullet and then flies horizontally away.

Lamppost, Checkpoint
Nemesis Compressed
|
$A6A96
|
$79278
|
Although placeable in several zones with debug in both prototype roms, it isn't part of the level layout in either of them.

Ball
Nemesis Compressed
|
$A8CA0
|
$7BE30
|
This ball seems to match up with the concept art (section coming soon!)
|

Drill, Rotating screw
Uncompressed
|
Not in this build
|
$2A86A
|
Located near the Hidden Palace Alpha background, this drill appears nowhere in the game, and isn't in any concept shots. It appears to take the place of some random unused art in the Beta-E build:

Lost CPZ Boss, Splattered Robotnik
Nemesis Compressed
|
$AA24A
|
$7D3DA
|
This interesting version of the CPZ boss seems to suggest they were originally planning to have this as the defeated robotnik animation. Note that the CPZ boss does not appear in either prototype, however the fact it is in the Beta-E prototype suggests that this boss had been on the drawing board for some time, even if no code had been made for it.
