Sonic & Knuckles DX

By Legobouwer9 & SyntaxTsundere
   

Sonic & Knuckles DX is a technical-focused ROM Hack developed by Legobouwer9 and SyntaxTsundere that attempts to answer the question of how much data can be fit into one fully lock-on compatible ROM, and how much the Sonic & Knuckles ROM alone could've changed and enhanced the combined Sonic 3 & Knuckles experience.

This hack mostly focuses on Lock-On Changes, so it is highly recommended to attach a Sonic 3 ROM to this.There are multiple tools online that will let you do this.

Features:

  • Alternating Zone Order
  • Proto Order when locked on and playing as Sonic & Tails, Final Order otherwise
  • Layout Fixes and Adjustments to the SK Zones and Carnival Night
  • Restored 1103-era music for Carnival Night, IceCap and Launch Base
  • Restored Big Arms fight in Launch Base
  • Animal Changes (Picky is no longer unused!)
  • UPMEM chip compatibility
  • An alternate build with a redesigned Flying Battery Zone made by SyntaxTsundere
  • Reduced LRZ2 Boss Hitcount
  • Significant code cleanup

Tools Used:

  • Notepad++ for ASM editing
  • Shell decompressors and recompressors for compressing files
  • SonLVL for level layout and object layout changes

This ROM hack is very good in incorporating the prototype music into the Sonic 3 and Knuckles package. It's also very cool in how the ROM is distributed as a S&K ROM and can be locked onto the final Sonic 3 ROM.

The only thing I can suggest is to please add the "Unused Music" track into the Sound Test. If you do this, this would be the most perfect and complete Sonic 3 and Knuckles package with the full prototype music soundtrack. I hope the "Unused Music" track gets added into a future release.
