This page covers one or more bugs in Sonic Adventure.

Cutscene bugs

Sonic reunites with Tails in Red Mountain

In Tails' story, when he reunites with Sonic he jumps onto the plane; but in Sonic's story, he just warps onto it.

This is because Sonic never leaves his Victory Pose, and even if he does he'll fail the jump unless an object is removed as Sonic's path is using an earlier version of the stage.

Not fixed in any version.

Egg Viper Introduction

When Sonic meets Eggman in the Egg Viper introduction he's supposed to do a pose, but it's called too early, causing it to overwrite the rolling animation, which then gets overwritten by the "action" animation.

Not fixed in any version.

Past Camera Bugs

When characters are in past cut scenes they're meant to have a special camera, but due to a bug related to transitions the camera only shows behind the player, but through hacking it's possible to see the intended cameras, the bug effects the following scenes.

  • EV008E (Knuckles 2A)
  • EV008E (Knuckles 2B)
  • EV0096 (Knuckles 3A)
  • EV0096 (Knuckles 3B)
  • EV00DB (Big A)
  • EV00DB (Big B)
  • EV00F6 (Super Sonic A)
  • EV00F6 (Super Sonic B)

Fixed in Sonic Adventure DX PC (2004).

Level bugs

Hedgehog Hammer crash


When selecting Hedgehog Hammer (ID 0) as someone other than Amy Rose, the game will crash as Sonic's object layout is incompatible. Why this also happens as other characters is this. If a character doesn't have a specific object layout for them, it defaults to Sonic's. As Sonic's object layout is using the Test Level's it's incompatible in the final game thus causing a crash. The stage doesn't crash for Amy as her object layout is compatible.

Fixed in Sonic Adventure DX: Directors Cut (Removed incompatible objects).

Emerald Coast loop-de-loop


After the player finishes the cave part of Emerald Coast, when they head to the loop-de-loop, if they stay on the right side of the screen they will fall through the floor.

Not fixed in any version.

Hub World bugs

Purple Hint Boxes


In the Egg Carrier's main hall the hint boxes are purple, to understand why, we must learn about the lighting engine. Sonic Adventure has a palette based lighting engine called Lantern, it works by using Diffuse and Specular palettes, to learn more about LANTERN, go here.

Fixed in Sonic Adventure DX: Directors Cut.

Standing on the burger man statue


In the original Japanese version it was possible to stand on the burger man statue. That's really it.

Fixed in Sonic Adventure (1999).

Chao Garden Bugs

Evening and Night Lighting


Even though the Mystic Ruins Chao Garden can take place at evening and night the lighting doesn't change, even though there's files for it.

Fixed in Sonic Adventure DX: Directors Cut.

Chaos don't spawn


Sometimes in the Egg Carrier Chao Garden your Chao won't spawn.

Fixed in Sonic Adventure DX: Directors Cut.

Boss bugs

"The Man 3" poster


The billboard in the Egg Walker is using the wrong poster as the mapping is using an older version.

Fixed in Sonic Adventure DX: Directors Cut.
