How do you get debug mode for Sonic the Hedgehog 2?

Answer 1

To get debug mode for Sonic 2 you need to get level select first.

To unlock level select, go to the options menu from the title screen and go to sound test. There you need to play the following sounds in order: 19,65,09,17. You will hear a chime meaning you did the code correctly.

Hold x and press start and you'll go back to the title screen. At the title screen,

hold B and press start. Then voila! You've unlocked level select. Now to get debug mode go to sound test again. It's on the right side in the level select menu. Play these sounds in order: 01,09,09,02,01,01,02,04.

Again, you will hear a chime meaning you did the code correctly.

Now highlight the zone you want to go to and hold B and press start. Press A after you get to a zone and you'll be in debug mode!

In debug mode, press B to change the selected object and press X to place it where you want. You can press A again to go back to being Sonic.

If you want to be Super Sonic without getting the chaos emeralds, go to level select and play these sounds in order twice: 04,01,02,06. Then highlight a zone, hold B and press start. Get 50 rings and BOOM! You're SUPER SONIC!!!

To make things easier you can just place 50 rings in debug mode and use those. Have fun : )
