Independent developer Serenity, operating under the name Serenity Theater, has demonstrated a functional VTuber software rig running on original PlayStation 2 hardware. The project, titled “Serenity VTuber Rig V1,” utilizes the console's native processing power to render a 3D avatar, bypassing the need for modern PC-based emulation.

Quick Facts

  • Platform: PlayStation 2
  • Core Hardware: PS2 Emotion Engine
  • Development Status: Early prototype/Build V1
  • Tracking Method: Network-based data from a PC-side Python script

How the PS2 VTuber Rig Functions

In a demonstration shared on X, Serenity showcased a wireframe model that updates in real-time based on yaw, pitch, and roll data. The developer emphasized that the console is doing the heavy lifting, stating there are no tricks or emulation involved in the rendering process. The software leverages the PS2SDK, an open-source library collection designed for homebrew development on the platform.

While the PS2 handles the rendering of the avatar, the system is not yet fully self-contained. Positional tracking is currently handled by a Python script running on a PC, which transmits the necessary movement data to the console via a network connection every frame. The resulting output can then be captured for streaming using standard software like OBS.

Future Development and Potential

Serenity has indicated that this project is currently in its early stages. When asked about the possibility of rendering these avatars within actual PS2 games, the developer noted the current focus is simply on the display of the model, though they did not rule out future functionality.

Future goals for the software include:

  • Full-body tracking: Plans are in place to integrate DIY hardware to support more complex movement.
  • Native face tracking: The developer is exploring the use of the PS2 EyeToy camera, though they expressed reservations regarding the camera's original build quality.
  • Portability: Because the software is built on a hardware abstraction layer, there is potential for it to be ported to other consoles from the same era.

The developer has expressed a commitment to making the software more user-friendly as development progresses. While no official release date or public download has been announced, the project has already drawn attention for its unconventional use of 26-year-old hardware to replicate modern streaming technology.
