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

Why is it only Sonic & Tails' campaign that features the beta Flying Battery?
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.
