Sonic Delta 40Mb (also called Sonic Delta Next) is a ROM hack for the SEGA Genesis that modifies the original Sonic the Hedgehog. It was entered in the 2023 Sonic Hacking Contest, a community event where creators showcase their modifications. This hack is not an official release but a fan-made project that expands on the base game's code and assets.

How to Play Sonic Delta 40Mb (Sonic Delta Next) Online

Getting Started

When the game loads, you will see a title screen with a modified Sonic logo. Press Enter to start. You control Sonic through a series of levels redesigned or added by the hack's creator. The core objective is the same as the original Sonic the Hedgehog: reach the end of each stage while collecting rings, avoiding spikes and pits, and defeating enemies by jumping on them.

This hack may alter level layouts, enemy placement, and even introduce new mechanics not found in the original. Pay attention to any text or tutorial hints that appear on screen. Since it is a ROM hack, there is no official manual, so exploration and quick reflexes will help you discover how it differs from the classic game.
