Harder Project

From Sonic Retro

Harder Project is a hacking team led by Eduardo Knuckles. Their currect project is the Sonic Harder Levels Project with the goal of having harder levels in every Mega Drive Sonic game. For now, however, Sonic and the Mystic Gems, Sonic In Eggland and Mobius Evolution, three hacks of Sonic 1, are the current works being developed by the project.


The Harder Project's Team is responsible to make harder but pleasantly playable Sonic hacks of the original titles for the Sega Mega Drive. The project involves all hackable Sonic games in a way to reprogram it to make completely new games. At first, the project was created only to edit level layouts in Sonic 1, but the ideas and the knowledge of Eduardo Knuckles increased significantly to make the hack more than just a simple layout edit. When he met HPZMan, he told him about possible ideas for the future - like changes in music, art and etc. Then Eduardo Knuckles decided to take the ideas of HPZMan afloat, to turn this simple hack into this great and beautiful project that is Sonic 1: The Harder Levels. As time went on, new people were showing us their knowledge, that's when we decided to turn this simple hack into a team effort. The Sonic Harder Levels Project.
