Play Sonic Delta Reloaded Online

Summary

Sonic Delta Reloaded – sometimes called Sonic Delta Next or simply Sonic Delta – is a fan‑crafted ROM hack that stitches together Sonic the Hedgehog 1, 2, 3 and Knuckles into one seamless adventure. Esrael Neto built the project to showcase what the original Genesis titles could have been, pulling in deleted stages and prototype content from Sonic 2, along with beta‑era graphics and music that never made it to retail.

The hack also resurrects badniks that were cut from the final releases and throws in a handful of brand‑new boss battles, giving longtime fans fresh challenges while preserving the classic feel of the series.
