From Sonic Retro
These are cheat codes which can be accessed by inputting button sequences or by various other methods.
Cheat Codes, All Versions
- Unlock Amy in the Sound Test menu: In the 'colour test' screen (accessible via the 'options' menu), change the left-hand colour bars to <00><00><00>, <06><0B><11> and <00><08><17>, going from top-to-bottom.
- Level Select & ingame Debug Mode: Again, enter the 'colour test' screen via the 'options' menu. This time, enter on the left-hand side of the screen <06><0B><11> and <04><00><04>, again looking from top-to-bottom. During gameplay, press Start to pause the game - you can now move freely around the level. Notes:
- World Entrance Level 0 is the normal world lobby, level 1 is the penultimate boss, level 2 is Metal Sonic Kai, and all the others crash the game.
- Special Stages number from 0 (0 is the first, 1 is the second, etc.). Each Special Stage starts you off with 200 rings. Once completed, a Special Stage takes you back to the title screen. After completing a Special Stage, and regardless of which one, Not Used level 0 will show the bad ending (but not the screen with the Chaos Rings).
- Activate 'Hidden' Character: To activate Wechnia, select the character labeled as '**********', then begin a game as usual. Note that this character occupies the second character slot, the first being Mighty the Armadillo - a sprite edit of Sonic from the Crackers beta (presumably the first character) and Tails (the deleted '**********' character). In earlier protos Wechnia has flying capabilities.
