Sonic the Hedgehog CD/Bugs

Back to: Sonic the Hedgehog CD.

Running animation

Sonic's running animation is positioned two pixels too high, meaning he does not appear to make contact with the ground. While the design of the first three stages makes this difficult to see, it becomes obvious from Quartz Quadrant onwards.

Not fixed in any version.

Title card drawing priorities

In some levels, rings are drawn on top of title cards.

Not fixed in any version.

"I'm outta here" collisions

In the controller is left untouched for 3 minutes, Sonic will attempt to jump off the screen and the player will lose a life. However, Sonic will continue to interact with some objects as he falls (for example, speed tunnels), sometimes leading to the game continuing as normal.

Not fixed in any version.

Quartz Quadrant boss

While the boss of Quartz Quadrant explodes, the capsule graphics and palette are loaded in. This causes the boss to change colour for a couple of seconds.

Not fixed in any version.

Time travel issues

By design, level layouts are adjusted as Sonic travels between different timezones. There are occasions, however, where time travel can lead to Sonic getting stuck.
