Эти пять бет, названные от Бета 4 до Бета 8 (англ. Beta 4 - Beta 8) в архивах Sega QA, являются внутренними тестовыми билдами, которые простираются восемь дней во время почти полного завершения над работой проекта Sonic the Hedgehog 2. Все шесть прототипов были выпущены drx как часть колоссального дампирования прототипов 23 февраля 2008 года.

Пока среди версии до Беты 4 не были найдены в архивах, окончательный релиз прототипа от 14 сентября подтверждает, что прототип CENSOR был создан в периоде Бет с 1 по 3.

Intro / Title Screen

Beta 4 lacks "Sonic and "Tails" / Miles In" screen, and shows this version of the text in all Beta builds.

September 14, 1992 to Beta 4	Beta 5	Beta 6 to Beta 7

Beta 8 onward

• The title screen in Beta 4 is the same as in the September 14, 1992 and CENSOR builds. This title screen is known for being used in non-Japanese instruction manuals.
• Beta 5's title screen changes to the one from the final version, but it's missing the TM symbol and the "Options", uh, option.
• Beta 5's title screen changes the color of the selected option from orange to the final's yellow shade.
• Beta 6 adds the Options menu and a TM symbol to the title screen. In this build and Beta 7, the "TM" uses the blue font palette instead of the yellow one.
• Beta 8 colors the TM symbol yellow and spaces the copyright graphic differently.
• In Beta 6 to Beta 8, the Options menu is called "Option", singular. This was corrected in REV00.

Демо игры

Во всех бета-билдах, демо проигрываются в таком порядке: Chemical Plant, 2P Emerald Hill, Casino Night, Hill Top. Они до сих пор используют ту же вставку, как и в прототипе Nick Arcade с движением из старого демо Hidden Palace для Casino Night; понятно, что запись новых демо не было преимуществом.

В финальной версии есть записи новых демо, которые проигрываются в порядке зон: 2P Emerald Hill, Chemical Plant, Aquatic Ruin, Casino Night.

General Changes

Dying

• In Beta 4 and Beta 5, the camera still follows the player after they die. Beta 6 properly locks the camera.
• In Beta 5, objects will keep moving after the player dies.
• In Betas 5 and 6, if the background is scrolling when the player dies, it won't stop scrolling until the screen fades out.

Spin Dash

In Beta 4 to Beta 7, the amount of time the screen is locked after the player lets go of the Spin Dash is exactly 20 frames, regardless of how fast the player is going.

This can cause problems when the Spin Dash is revved up too much, especially when playing as Super Sonic: the player can outrun the camera and bypass most sprite-based obstacles, like the barriers in Wing Fortress Zone and Eggman's running sprite in Death Egg Zone.

To fix this, the screen-lock time was changed. The game now takes the initial inertia after the Spin Dash into account, and freezes the screen between 20 (the slowest Spin Dash speed) to 12 (the fastest Super Sonic Spin Dash speed) frames. The player is now unable to outrun the camera after a Spin Dash.

If the player is Spin Dashing on a platform that crumbles when the player steps on it (like the rectangular platforms in Aquatic Ruin and the ledges in Oil Ocean), they'll remain in the air until they stop holding Down. This wasn't fixed until REV00.

Super Sonic

The Super Sonic transformation is in various stages of completion:

• Beta 4 has no code to handle the Super Sonic transformation or ring drain, though the actual Super Sonic code is partially implemented. Use Pro Action Replay code FFF65F:0001 to enable the Super Sonic palette, FFFE19:0001 to enable the Super Sonic sprites and increased jump height, and FFB02B:0006 to enable invincibility and speed shoes.

Super Sonic doesn't produce any invincibility sparkles when he runs.

The increased speed and acceleration are not enabled - this is set by the transformation sequence in later versions - but the player can get the increased speed/acceleration if they either get a Speed Shoes monitor and let it expire, or go into the water and then jump back out.

• Beta 5 implements the transformation, but it's bugged: The game checks if RAM address FFB0 (a boolean that is set after a Special Stage is cleared) is 7, when it should be checking FFB1 (Chaos Emerald count). Use PAR code FFFFB0:0007 and get 50 rings to enable the transformation.
• From Beta 6 onward, the Super Sonic transformation is properly enabled.

• In all Beta versions, Super Sonic defaults to the standard blue palette while underwater. Corrected in REV00.
• If Super Sonic starts the underwater countdown timer and then either gets out of the water or gets an air bubble, the invincibility music will play instead of the Super Sonic track. Fixed in Beta 6.

End of Act

In Beta 4 to Beta 7, the player keeps their shield at the end of the Act. This extra graphic, plus the sprites used for the results screen, can cause some of the signpost graphics to blank out. From Beta 8 onward, the player loses their shield at the end of the Act.

In all Beta versions, Sonic can keep his Super transformation at the end of the Act. The ring total on the results screen will be whatever rings the player had when they passed the signpost.

There's one problem with this: Super Sonic's invincibility stars are overwritten with font and continue icon graphics, leading to the mess you see here. The final version fixed this by transforming Sonic back to normal at the end of the Act, but ended up introducing a much worse bug.

Beta 4	Beta 5 to Beta 8	REV 00 onward

The Act Clear screen has an additional period after the word "Act" but before the act number. The Total text is also higher up due to the lack of a Perfect Bonus. The period was removed in Beta 5, but the spacing (and the existence of the Perfect Bonus) wasn't changed until the final.

Beta 6	Beta 7	Beta 8 onward

Beta 6 and Beta 7 use Sonic's continue icon for Tails. Beta 6 calls Tails "Sonic" at the end of the Act, while a new continue icon was drawn for Beta 8.

Beta 4	Beta 5 onward

In Beta 4, the camera locks earlier than it should whenever an Animal Capsule is onscreen, causing the Capsule to be off-center.

Misc.

If the player holds any of the jump buttons as the Act starts, they'll start in the air after the title card scrolls off. Fixed in Beta 8.

The collision check for getting crushed seems to be less lenient in Beta 4. The easiest place to see this change is in the lower path at the start of Chemical Plant Act 2, on the platform above the second transport tube with the Super Ring monitor. In Beta 4, if the player walks all the way to the left, they'll be crushed. In other versions, they're able to get to the end without dying.

• Holding Up / Down to scroll the camera up or down wasn't put back in the game until Beta 5.
• Beta 4 still uses the original spike behavior from Sonic 1. From Beta 5 onward, spikes won't hurt the player if they're flashing from post-damage invulnerability.

Debug Features

Stage Select

Accessing the stage Select changed between Betas:

• In Beta 4 and Beta 5, the stage select is accessed by pressing A + Start while selecting "1 PLAYER" at the title screen. There is no code required.
• In Beta 6 and Beta 7, the player must enter Up, Down, Down, Down, Down, Up, then press A + Start while selecting "1 PLAYER".
• Beta 8 keeps the previous code and adds the final code: Enter the options menu, go to the sound test, then enter 19, 65, 09, 17. Exit the menu and press A + Start while selecting "1 PLAYER".

Саймон Вей - 21 августа 1992	14 сентября 1992 - Бета 4

Экран Выбора уровня в Бете 4 примерно тот же самый, что и в прототипе Саймон Вейя. Wood Zone и Genocide City Zone были убраны, Sky Chase Zone и Sky Fortress Zone были добавлены, и Death Egg Zone имеет только один Акт. Wing Fortress до сих пор зовётся как "Sky Fortress" после прототипа от 21 августа, и даже если Hidden Palace Zone есть в списке, то его нельзя выбрать.

Беты 5 и 6 пытаются использовать ту же установку, однако новое лого заглавного экрана перекрывает много текста.

Бета 7 представляет финальную версию Выбора уровня. Однако, в этой версии, игрок не может нажать Лево или Право, чтобы перейти на другую колонку. Эта фича была вставлена в Бете 8.

Номера звукового теста в Бете 7 заглючены в первый раз. Двигая цифрами в этой настройке исправляет это.

Debug Mode

• This is enabled by default in Beta 4 and Beta 5: Just hold A + Start before entering a stage.
• Beta 6 to Beta 8 require a code: Press C, C, Up, Down, Down, Down, Down, Up, then hold A + Start before entering a stage.
• In Beta 4 to Beta 6, debug mode does not enable edit mode, only the debug information on the HUD and the debug controls when the game is paused. Use PAR code FFFE08:0001 to activate edit mode.

Beta 4 to Beta 6 will not show the collision changer objects in debug mode, even if edit mode is activated. In Betas 7-8, the collision changer objects are always visible as long as debug mode is active. In the retail versions, those objects are only visible in edit mode.

The "red ring" objects (the pinball mode toggles in Casino Night and palette changers in Wing Fortress) are visible in Betas 7 and 8 as long as debug mode is active. These are the only versions in which the player can see these objects.

Special Stages

Each Special Stage has a different layout to the final game - bombs don't even make an appearance until Stage 4. All of the stages were changed to their final layouts in Beta 5 except for Stage 6, which stuck around until Beta 8 before finally changing in REV00.

Ring Requirements (Sonic and Tails)

	Stage 1				Stage 2				Stage 3				Stage 4				Stage 5				Stage 6				Stage 7
Beta 5	40	80	140		60	110	150		60	110	160		40	105	160		60	100	170		50	90	140		100	150	190
Beta 6 to Beta 8	40	80	140		50	100	140		60	110	160		40	100	150		55	100	160		50	90	140		100	150	190
REV 00 onward	40	80	140		50	100	140		60	110	160		40	100	150		55	110	200		80	140	220		100	190	210

The ring requirements for Sonic & Tails together were adjusted twice after Beta 5. In Beta 6, the ring requirements for Special Stages 2, 4, and 5 became more lenient. In the final version, the ring requirements for Stages 5, 6, and 7 are stricter. Stage 5 has a more difficult third round, Stage 6 is still using the old layout as mentioned previously, and the number of rings for Stage 7 went up considerably - it's notoriously difficult if there isn't a second player controlling Tails.

Ring Requirements (Sonic / Tails Alone)

	Stage 1				Stage 2				Stage 3				Stage 4				Stage 5				Stage 6				Stage 7
Beta 6 to Beta 8	30	70	130		50	100	140		50	100	150		30	95	145		45	80	145		45	85	135		90	140	180
REV 00 onward	30	70	130		50	100	140		50	110	160		40	110	150		50	90	160		80	140	210		100	150	190

The ring values for Sonic / Tails alone also changed, but the changes weren't as drastic as Sonic & Tails together, only differing between 5-15 rings. Note that these changes made Special Stage 4's ring requirements harsher when playing solo than when playing as a team. The stages have different palettes to the ones used in the final, though the palettes for Stages 1, 3, and 5 were eventually reused for Stages 2, 5, and 7 respectively. These palettes are also present in Beta 5, but the stages use their final palettes from Beta 6 onwards.

Beta 4	Beta 6 onward

In Beta 4 and Beta 5, rings sometimes disappear when the half-pipe is doing the transition animation from straight to curved. Once the tube has finished curving, the rings will reappear. This seems to have been fixed in Beta 6. The "X RINGS TO GO!" message doesn't appear until Beta 6.

In Betas 7 and 8, the message will keep flashing even after the player gets enough rings. The yellow parts of the stage flash different colors occasionally in this version including green, red, and white. This is due to the cycling palette used for the rings that mark the end of each section being loaded too early. In Beta 4, the background doesn't flash different colors when obtaining the 7th Chaos Emerald.

The color order of the Special Stages the Emeralds represent are different compared to other versions. In Beta 4, the order they're collected is represented in the table below (with color positions kept in the final in bolded text):

Beta 4 to Beta 8	Green	Yellow	Red	Pink	Purple	Cyan	Grey
REV 00 onward	Cyan	Purple	Red	Pink	Yellow	Green	Grey

Beta 4 to Beta 5	Beta 6	Beta 7 onward

Beta 4 only displays one Chaos Emerald on the screen no matter how many Emeralds the player has. In Beta 4 and Beta 5, the results screen uses the name "Tails" regardless of the console region, and the Emeralds are positioned higher. Beta 6 attempts to add the red triangles seen from the normal results screen to the Special Stage results, but something went wrong and the graphics are badly corrupted. This affects the small font and the Emerald graphics. This was fixed in Beta 7.

Beta 5	Beta 6	Beta 7 onward

Beta 4 and Beta 5 don't acknowledge that the player has collected all of the Chaos Emeralds. Beta 6 adds the "All Emeralds" message but swaps around words a few. Fixed in Beta 7. By Beta 6, the letter E in Emerald was also kerned to the letter M.

2 Player VS

Normal Stages

• 2P is always called Miles in Beta 4, regardless of region. In Beta 5, he's always called "Tails". It changes depending on the console region starting in Beta 6.
• If Tails hits a shield or invincibility monitor, the shield / invincibility stars won't be displayed. Fixed in Beta 6.
• The Eggman monitor doesn't do anything in Beta 4 and Beta 5.

Time Over

There's an oversight in Beta 4 and Beta 5: If either player gets a Time Over, the stage will reset and then immediately go to the results screen. This sets their score, time, ring, total ring, and item box numbers to what they were the last time they hit a checkpoint; or, if they never hit a checkpoint, to zero. Beta 6 fixes this by jumping to the results screen after a Time Over. Beta 6 is the first version to implement a 60-second timer after one player gets to the end of the Act.

Special Stages

Tails is always called "Miles" in Beta 4 and Beta 5. It changes appropriately from Beta 6 onward.

In Beta 4, after the first round of a Special Stage, the "MOST RINGS WINS!" message was originally written as "WIN TWICE WIN ALL!" This message was revised in Beta 5.

Бета 4 - Бета 5
Бета 6 и позже

Палитры для Special Stage в 2P VS также различимы от тех, что есть в финальной версии.

Ending / Credits

Ending

Beta 4 has no ending at all. After the Death Egg cutscene plays, the game resets to the Sega logo.

In Beta 5, a rough version of the final cutscene has been implemented: Sonic falls briefly before Tails catches him. Tails flies straight from the right - there's no attempt to make it seem like he's moving the plane up to catch Sonic. After 64 frames, Tails flies off to the right, off the screen. After about three seconds, the cutscene ends and the game resets to the Sega logo. There is no special ending for Super Sonic.

In Beta 6, the cutscene is close to what it would be in the final version, but the part where Sonic jumps off the plane is glitched. The large Tornado and large Sonic sprite both spawn in the bottom-right corner. There's no special ending for Super Sonic, and finishing the game with Tails plays Sonic's ending.

Beta 7 spawns Sonic at the right place, but forgets to delete the tiny Sonic & Tails sprite at the bottom-right corner. This was fixed in Beta 8. Beta 7 is also the first version to implement a special ending for Super Sonic; it's identical to the one in the final version. Tails is still missing his ending cutscene.

Something in Beta 8 glitched the Super Sonic ending up: Sonic starts out Super, but after a second he transforms back into regular Sonic, running on air.

The game loads the large Super Sonic sprite at the start of the ending, but tries to give it the normal Sonic tilemap once he transforms back, resulting in this glitched mess.

Бета 8 является первой версии с концовкой для Тейлза. Почти сделано, за исключением той частички, где нет спрайтов хвостов для Тейлза.

Credits

In Beta 6, there's an odd segmented line in the middle of the screen. This was removed in Beta 7.

• They colored the 2 in "SONIC 2" yellow in Beta 7.
• Section names are white in Beta 6, the same as the rest of the text. From Beta 7 onward, they're yellow.
• Peter Morawiec is mistakenly rendered as "Morawiec Petr" in Beta 6.
• Beta 8 adds France Tantiado, Rick Macaraeg, and Locky P to the Special Thanks. It also splits up the Special Thanks list into two screens.
• In Beta 6, credits go out of sync with track - music ends before the Special Thanks screen. In Beta 7, the credits fade out just before the track ends. Beta 8 properly syncs the music to the credits.

A Sonic 2 logo was added at the end of the credits in the final version. The credits had to be sped up a bit to fit this screen.

Changed Graphics

Invincibility

Simon Wai to Beta 7	Beta 8 onward

From the Simon Wai prototype up to Beta 7, the main part of the invincibility effect is two sets of large sparkles that go into one of three different positions every nine frames. Beta 8 uses a more complicated effect: A circle of rapidly moving invincibility sparkles that cycle every 48 frames.

Simon Wai to Beta 7	Beta 8 onward

The sub-effect of the invincibility effect, in earlier versions, is a collection of small invincibility sparkles that trail the player and change direction depending on what direction the player is heading... in theory. This was working fine in the Simon Wai prototype, but after that something in the code glitched.

The trail moves in the correct direction if the player is grounded. If the player is jumping, the trail will move southwest, and if they're falling the trail will move northeast, regardless of the direction the player is facing. The final version fixes this by completing changing the sub-effect. The player will now leave behind two large rotating invincibility sparkles. The complete rotation cycle lasts 120 frames.

Stego

Nick Arcade to Simon Wai
August 21, 1992 to Beta 4

Stego's sprite is the same as in the August 21, 1992, September 14, 1992, and CENSOR builds. It was deleted in Beta 5.
