Sonic the Hedgehog Mobile

Sonic 1 on a mobile phone...before the iPhone port. Depending on the service provider, the game was either provided as one full game or in two parts, as Sonic the Hedgehog Part 1 and Sonic the Hedgehog Part 2.

Unused Graphics


This UFO was seen in early screenshots and footage of the Genesis original's Marble Zone, but why is this here...?





Leftover graphics from the removed Special Stage remain in the data.

Cheat Menu


At the title screen, press 2, 3, 0, 6, 9, 1 (the US/Europe release date of the original game) to unlock the cheat menu.

INVINCIBILITY: Makes you invincible.

UNLOCK LEVELS: (Part 1 only) Allows you to play all of the levels from Part 1 and Part 2. This option doesn't exist in the Japanese release, as it wasn't released as two separate games in Japan.

AMPHIBIOUS: (Part 2 and Japanese release only) Makes it impossible to drown.

EMERALDS: Allows you to set the amount of Chaos Emeralds you have.

FPS: Shows the current number of frames-per-second in the upper-left corner of the screen.

COORDS: Shows Sonic's coordinates in the upper-right corner of the screen.

CAMERA: Lets Sonic move in all directions without falling. Use # to toggle it mid-level.

Revisional Differences
There was a second release of the game for Verizon phones that strangely removed all of the sound effects.
