To activate the codes, do the following steps: Start a no save game. Choose a character. When the SEGA logo pops up, press all of the letters in order. Then put 2 fingers at the bottom of the screen. You'll enter a place where you can select levels and do cool stuff. Go to sound test and play whatever numbers you pick: 0, 0, 0. (Won't play anything, but it will take you to a character selection screen where you can select power-up monitors that you can find in the level or flight abilities and air caps.) 4, 1, 2, 6. (This gives you all the Chaos emeralds. Collect 50 coins and then double jump. You'll become Super Sonic.) 1, 9, 9, 2, 1, 1, 2, 4. (This will allow you to enter Debug mode. Tap the upper left corner of the screen to enter Debug mode. Place items by jumping and switch items with the plus and minus buttons at the top of the screen. To exit Debug mode, click the upper left corner again. To enter the level select again, enter Debug mode and press the Pause button. This will take you back.)
