Hello! Greenknight9000 here and I'm here to give you all a treat I've been working on the past few months. It started as me wanting to recreate my old S2 Hidden Palace Zone stage into something more consistent with other Mugen Sonic stages, and it snowballed into me doing stages that other people haven't done!
So, what's in this pack, you ask? Here's what's in store:

• Green Hill Zone Mountains (AKA the Tokyo Toy Show version of Green Hill Zone)
  

• Rocky Mountain Zone (from the Sonic the Hedgehog Prototype Archives videos on YouTube, sprites provided by KatKuriN and ManiacShard themselves!)
  

• Marble Zone (Complete with UFOs!)
  

• Rock World Zone (from Sonic 2: The Secret Zones)
  

• Hidden Palace Zone (From Sonic 2 Beta)
  

• Hidden Palace Zone Depths (AKA Segapede's Hidden Palace Zone)

• Cyber City Zone (From Sonic 2: The Secret Zones)
  

• Hidden Palace Zone (From Sonic 3 & Knuckles)
  

More might be to come in the future, so stay tuned! I'm really proud with how these turned out! Feel free to give feedback so I can hopefully improve these further! Community Contributions are always accepted and welcome! Any extra help is always nice! Hahaha
