Anomaly #0003, designated as "Sonic 4ever", is a now-lost ROM hack of Sonic the Hedgehog 4: Episode I. This fan modification reportedly improved visuals, gameplay, and general quality over the base game. However, its anomalous properties are not technical, but rather informational.

Every attempt to collect consistent data about the ROM yields conflicting information. One informant described the game as featuring Sonic, Tails, Knuckles, and Amy as playable characters. Another claimed Amy was replaced by a completely original character. A third described Shadow as playable and mentioned a fully-developed "city stage."

The same contradictory nature applies to the story, with multiple, mutually exclusive narratives being recalled by different sources. Documenting every variation would be prohibitively time-consuming.

The B.G.I. has classified this anomaly as both Indescribable in risk and status due to the impossibility of verifying any factual version of the game’s existence or content. Any new leads or sightings should be reported immediately.
