As of 2024-2025, the Xenia emulator (specifically build) runs Sonic Generations very well , but not perfectly.

Sonic Generations is unique because it serves as a "best-of" collection. Players control both and Modern Sonic across reimagined versions of iconic levels like Green Hill Zone, Chemical Plant, and City Escape.

The gameplay in the Sonic Generations 360 ROM remains faithful to the original. Players control both Classic Sonic and Modern Sonic, each with their unique abilities and styles of gameplay. Classic Sonic's sections are reminiscent of the classic Sonic games, with an emphasis on linear level design and speed. In contrast, Modern Sonic's sections bring a more contemporary feel, with a greater focus on exploration, physics, and combat.
