Castlevania: Circle of the Moon Ported to Sega Genesis by Dedicated Fan Developer

The Sega Genesis, also known as the Mega Drive in select regions, continues to captivate retro gaming enthusiasts through impressive fan projects.

One standout example is the ambitious port of Castlevania: Circle of the Moon, originally developed by Konami and released as a Game Boy Advance launch title in 2001.

This latest fan-made effort joins an expanding suite of Castlevania classics—such as Symphony of the Night, Rondo of Blood, and Super Castlevania IV—ported by talented programmers to the storied 16-bit hardware. The driving force behind this project is the developer known online as @andorvogel4768.

Throughout the past month, they have shared detailed updates and progress videos on YouTube, showcasing the technical challenges and milestones met in adapting Circle of the Moon for the Genesis platform.

Among the notable recent developments, save game functionality has been a significant focus.

In a statement recapped through their update video, @andorvogel4768 explained spending over a week implementing SRAM features that now allow players to save and load progress.

The interface for this functionality permits the creation of up to three separate save slots via the Data Select Screen—an essential feature adapted from the title menu of the original Game Boy Advance release.

Work remains ongoing to incorporate the Save Room mechanic, a key element of the source material. Beyond technical groundwork, creative fidelity is also a priority for this port.

"I recently introduced a new enemy type, the Bat," explained the developer in an update.

They emphasized their commitment to authenticity by researching the original motion patterns and carefully recreating them for the Genesis version.

These technical and artistic decisions ensure the gameplay remains true to the spirit of Circle of the Moon, while adapting seamlessly to the capabilities of the Genesis. The ongoing progress has been highlighted by other members of the retro gaming community, notably @St1ka, who has drawn attention to the level of polish and dedication evident in the project.

The most recent demonstration video features an atmospheric soundtrack by @jorgerfm364, enhancing the nostalgic appeal. This port not only demonstrates the enduring passion of the Sega and Castlevania fanbases but also highlights the technical prowess required to bring such ambitious projects to life.

As the roster of Castlevania games available on the Sega Genesis grows, retro gaming communities and preservationists continue to celebrate the talented individuals preserving these classics for new audiences.
