Changes from the Genesis Version

view on tcrf.net

This is a sub-page of Sonic the Hedgehog 2 (2013).

To do:
this page only just barely started, there are still more differences to cover

Gameplay Differences#

  • The game now runs in widescreen. Some of the boss battles and arenas are modified to account for this, such as Aquatic Ruin Zone and Death Egg Zone (Mecha Sonic only).

Graphical Differences#

  • Smooth sprite rotation has been implemented for certain sprites that used dedicated sprite frames to convey the effect in the original version, such as the drills of Mystic Cave Zone's boss, and the cogs in Metropolis Zone.
  • Many other objects have also had their animations smoothed, such as the Rexon Badnik.
  • For the SEGA splash screen, the original scaled up Sonic's in-game sprite. The Retro Engine version uses a new, higher resolution sprite, with new detailed shading.

Genesis

2013 version

Audio Differences#

  • All samples are higher fidelity compared to the Genesis original.
  • The only non-level song to have a sped-up version is the Invincibility theme. A side effect of this is that encountering the boss while wearing Speed Shoes only plays the Boss theme at normal speed, rather than the sped up-version.
  • Hidden Palace Zone uses the Mystic Cave 2 Player music, like in the prototypes, and not the original final's Song #10 assignment. Proto Palace Zone opts for Song #10.
  • The Wing Fortress Zone boss now has sounds for charging up and firing its laser, taken straight from Sonic 3 & Knuckles.
  • Death Egg Zone also has new sounds for closing the Death Egg Robot's head, and explosion sounds when escaping, also taken from Sonic 3 & Knuckles.

Level Differences#

To do:
Mystic Cave also has brand-new Knuckles-only paths in many places.

Chemical Plant Zone#

Act 1#

  • There are two new secret monitors near the start of Act 1:
  • The two monitors that were introduced in Knuckles in Sonic 2 are present:
  • There's a whole new path exclusive to Knuckles, as well as a Knuckles-exclusive checkpoint area:

Act 2#

  • The entire second half is filled with new Knuckles-exclusive paths.

Hill Top Zone#

Act 1#

  • There is now a brand-new Knuckles-only section near the beginning:
  • There is also a new Knuckles-only section near the entrance to the first underground section:

Mystic Cave Zone#

Act 2#

  • The infamous spike pit has been de-spiked. Jumping down it now sends you to Hidden Palace Zone.
    • However, this is a complete level with a unique layout and boss, unlike the one featured in the prototypes.
    • You can still access the original level from the level select by playing the sounds 03, 03, 0B, 10, 10, 10, 04, and selecting Hidden Palace.

Wing Fortress Zone#

  • The lone diagonal conveyor belt now actually functions as a conveyor belt, unlike the original where it served no actual purpose.
