Super Sonic in Normal Levels (Sonic Adventure 2 Battle) — Action Replay?

No official Action Replay code exists. Super Sonic is hardcoded to Final Hazard (last boss) and 2P Battle mode (via cheat menu unlock). The game engine does not load Super Sonic's model/animations/states in standard stages.

Why AR Codes Fail

• AR modifies RAM values (lives, rings, timer). It cannot inject new code/assets or rewrite the character state machine.
• Super Sonic requires: unique physics, model, super music, invincibility flag, ring drain loop — all absent in level scripts.

Working Alternatives

• PC Mods (Steam / 2012 Port):
  • SA2 Mod Loader + Super Sonic in Stages mod (by Chad / Melpontro on GameBanana/Nexus).
  • Enables Super Sonic in any stage via separate character slot or transform key.
• GameCube / Wii (Nintendont): Same mods work via Nintendont + SD card + Action Replay / Gecko codes that patch the ISO in-memory (advanced).
• Dreamcast (Original): CodeBreaker + homebrew mods — extremely limited community.

Legitimate Unlock (2P Battle)

1. Collect all 180 Emblems.
2. 2P Battle → Select Sonic → Hold L + R → Press A → Super Sonic selectable (2P only).

For single-player stages: Play the PC version with mods. It's the only stable way.
