Sonic the Hedgehog 2 (iOS, 2013)
|Sonic the Hedgehog 2|
The 2013 mobile remake of Sonic the Hedgehog 2 is the third game in the Taxman/Stealth collection of remastered Sonic games. Like the 2013 Sonic 1 before it, the Sonic 2 remake replaces the rudimentary emulated version originally on the App Store and adds Knuckles, auto-match multiplayer, 60FPS, and widescreen support as well as running on the fan-made Retro Engine.
The remake is most notable for including a completed version of the famed Hidden Palace Zone, accessible in normal gameplay...although it uses the 2-player Mystic Cave tune (like the Simon Wai prototype of the Genesis original) rather than the otherwise-unused Song #10 that plays upon loading the Zone in the final, because they felt it was a better fit.
Figure out how to access the dev mode shown in the Egg Gauntlet/Proto Palace video.
The level select can be accessed the same way as in the 2013 Sonic 1 – start a "No Save" game and choose a character. On the SEGA logo screen, tap the letters S-E-G-A in that order once the entire word appears. If done correctly, you will hear the ring chime twice. Then hold two fingers on the bottom of the screen and wait. After the title screen appears, you'll be taken to the level select.
Game Config Menu
Play sound 00 three times in the Sound Test to bring up a "Game Config" menu. It replaces the more rudimentary menu from the 2013 Sonic 1.
- Player: Similar to the player select in the Genesis game's options menu, this allows you to play with Knuckles with Tails following, ala the default Sonic and Tails option.
- Items: Lets you choose between Sonic 2 items, hidden Sonic 2 items (all monitors display a "?" graphic), Sonic 3 items, and hidden Sonic 3 items.
- Flight: Toggles Tails' signature ability.
- Air Cap: Toggles the air speed cap.
Play sounds 01, 09, 09, 02, 01, 01, 02, 04 (the US/European release date of the original Genesis game) in the Sound Test. During gameplay, tap the upper-left corner of the screen to access the debug mode. To change the item you are placing, press the + or - on the top of the screen.
Tapping the lives counter in Debug Mode will take you back to the Level Select.
Eighth Special Stage
Similar to how the 2013 Sonic 1 added a hidden seventh Special Stage, this port adds an eighth Special Stage. By selecting sounds 00 through 07 in the Sound Test, you can change which Special Stage you go to. Playing sound 00 and selecting Special Stage takes you to Special Stage #1, 01 takes you to #2, and so on, with 07 taking you to #8.
The eighth Special Stage is purple, a color previously used exclusively in multiplayer Special Stages, and features a corkscrew loop.
As of Version 3.0.9, a code to access the original Hidden Palace Zone from the Nick Arcade and Simon Wai prototypes, complete with the "unused" Track #10, has been inserted. After entering the debug mode cheat (shown above), play the sounds 03, 03, 03, 0B, 10, 10, 10, 04, and choose "Hidden Palace" on the stage select.
As with the stage's original incarnation, it's incomplete and stops at a certain point. Rather than the "Master Emerald" acting as a breakable object, it instead warps the player back to the stage select. Another notable change that's been made is the fully-functioning water slide.
A scrapped zone called Egg Gauntlet was a first attempt at a boss attack zone, featuring some original artwork such as mechanical palm trees. It also uses graphics from the famous "Sonic Crackers" prototype of Knuckles' Chaotix. For whatever reason, SEGA did not approve of the level, and it was scrapped.
Data and artwork of Egg Gauntlet did remain and the zone was fully playable, albeit inaccessible by normal means. It features all bosses in the game except for Hidden Palace. There are no checkpoints, but there are rings between bosses.
As of Version 3.0.9, this zone was completely removed from the game, artwork and all.
Figure out how to access the dev mode shown in the video.
Most of these are, unsurprisingly, leftovers from the original Genesis game.
|"S" Monitor||Makes the player Super when broken. Breaking this monitor is the only way to become Super Tails in this game.|
|Three Shields Monitor||Toggles the Items option when broken. Changes to the monitors will take effect when you restart the Act or advance to the next Act.|
|Emerald Monitor||Breaking it will give you all the Chaos Emeralds, allowing you to turn Super with 50 rings. Breaking it again will take away the Chaos Emeralds.|
|Spring Monitor||The only monitor that isn't used in Debug Mode. This monitor also exists in the Nick Arcade and Simon Wai prototypes.|
|Leftover continue screen animation for Tails from the 2013 Sonic 1 port. Tails uses a different animation for the continue screen in this game.|
|Leftover Tails life icons from the 2011 Sonic CD port, present among Tails' sprites.|
|Leftover timer marks from the 2011 Sonic CD port, found within the HUD sprites.|
|No idea, honestly. Probably something related to the Retro SDK's level editor from which the game was built.|
