Sonic 3 and Knuckles Time Travel (Jdpense) (SHC2015) is a fan-made ROM hack of Sonic the Hedgehog 3 & Knuckles for the SEGA Genesis. It was created by Jdpense for the Sonic Hacking Contest 2015, a community competition where modders showcase their work. This is not an official Sega release, but a modification built on the original game's code, so you will need either original hardware with a flash cart or an emulator to run it.

Made by: Jdpense

How to play Sonic 3 and Knuckles Time Travel online

Getting Started

Boot the game just like any Sonic 3 & Knuckles ROM, but note this hack may have its own title screen or menu. Use Enter to start and Arrow Keys to navigate menus if needed. The core loop is classic Sonic platforming: run from left to right through zones, collect rings, defeat badniks by jumping on them, and reach the end of each act to progress.

This hack introduces a time travel mechanic that likely alters stages or allows switching between different time periods. Pay attention to new gimmicks or switches that let you shift the environment. Your objective is still to reach the goalposts, but exploration may unlock alternate paths or shortcuts. Since this is a competition hack, expect it to be shorter than the full Sonic 3 & Knuckles campaign.

If the menus are in English, controlling your character is straightforward: jump with X, run with S, and use spin dash by holding down then pressing jump. Some versions may require pressing Start to skip cutscenes. If you get stuck, experiment with the time travel button (likely mapped to Z or A, but check the controls list).

Sonic 3 and Knuckles Time Travel FAQ

Is there anything iconic or memorable about Sonic 3 and Knuckles Time Travel?

The most notable aspect is its time travel concept, which tweaks the original level layouts and adds new paths. As a Sonic Hacking Contest entry from 2015, it holds nostalgic value for fans of that era's modding scene.

Is Sonic 3 and Knuckles Time Travel exclusive to SEGA Genesis or did it appear on other systems?

This hack only exists as a ROM for the SEGA Genesis / Mega Drive, built from the base game's code. It was never ported to other consoles or released commercially in any form.

Can players save progress in Sonic 3 and Knuckles Time Travel?

Saving behavior depends on how the hack was programmed. The original Sonic 3 & Knuckles had a battery-backed save system for unlockables, but many hacks do not implement saving. If you are playing on an emulator, use save states to keep your place, as the hack may lack built-in save functionality.
