DO NOT CATEGORIZE THESE PAGES; THEY ARE BEING WORKED ON IN AN ATTEMPT TO REPLACE THE SONIC 2 BETA PAGE AS IT STANDS. BE PATIENT.

Cheat Codes

Level Select

Level select is enabled by default; just hit A+Start at the title screen.

Debug Mode

On the title screen, press C C Up Down Down Down Down Up. The Cs can be placed anywhere before the final Up. Then go into Level Select, select a level, and hold A until the level shows up.

Once in the game, the buttons now behave differently:

A Cycle through objects forward (when debug is on)
B Toggle debug mode on/off
C Place selected object (when debug is on)
Hold A + C Cycle through objects backwards (when debug is on)

Sonic, while turned into an object, can fly through walls and is not subjected to enemy attacks.

The HUD shows different information when in debug.
  1. Object's x-coordinate (hex)
  2. Object's y-coordinate (hex)
  3. Time in seconds (hex)
  4. Timer that bounces back and forth between 0000 and 0080 every three seconds (hex)
  5. Number of sprites on screen (dec)
  6. Rings counter (dec)

The origin, (x,y) = (0000,0000), is located at the upper-left hand corner of a level.

Night Mode

In level select, select a level and hold C until the level shows up. Objects on the Plane A High and Plane B High layers are highlighted, while those in the Plane A Low and Plane B Low layers are shadowed. What's the point?

how this mode is useful to Sonic Team for debugging.
