Sonic Delta Next

Sonic Delta Next is a Genesis ROM hack that merges all the iconic Genesis Sonic games into one long adventure. You can start from Green Hill Zone and make your way through dozens of stages from Sonic 1, Sonic 2, Sonic 3, and Knuckles. We recently added this classic mashup to our website because we know people love playing retro Sonic platformers with expanded features. This version doesn’t just recycle stages. It includes cut content, secret levels, and upgraded visuals—all wrapped into a single experience. You can even play as Sonic, Tails, Knuckles, or team them up for co-op runs.

Sonic Delta Next Game Features

• Includes around 37 stages pulled from Sonic 1, 2, 3, and Knuckles
• Play as Sonic, Tails, Knuckles, or Sonic & Tails together

• Unlock and explore beta content and hidden zones, like Sand Shower
