Shadow in sonic 1 — Cheat codes

While the demo is playing, hold A + B + C. Sonic will get confused, lose his place, and possibly die.

Control Mode

At the title screen, press Up, C, Down, C, Left, C, Right. While playing, you can pause the game and use A to restart, B for slow motion, and C for frame advance.

Level Select

At the title screen, hold A then press Up, Down, Left, Right. When you hear the chime, press Start. <p> If that doesn't work, try this: at the title screen, press Up, Down, Left, Right, hold A, and press Start. After doing this once, you only need to hold Start + A to enter the level select.

Extra Lives

In Green Hill Zone - Act 3, there is a 1-Up at the very bottom of the level. Collect it along with enough rings to make 100 for a second life. Next, grab the 1-Up at the top of the loop-de-loop and die. Repeat until you have enough lives.

Debug Mode

Enable Control Mode. After pressing Start to begin a game, hold A until you see Sonic. If you see a bunch of hex numbers on the top of the screen, you're in Debug Mode.<p>

To start debugging, press B, then you can select any sprite in that level and put it on the screen. To select a different sprite, press A, and to place it on the screen, press C. Note that sprite selection is different from Zone to Zone. Also, instead of displaying the time elapsed, it displays the number of sprites currently on the screen. Control Mode functions work as well.<p>

Note: This only works on the first production releases of Sonic.

(Sonic the Hedgehog) Cheat: Extra Lives

In Green Hill Zone - Act 3, there is a 1-Up at the very bottom of the level. Collect it along with enough rings to make 100 for a second life. Next, grab the 1-Up at the top of the loop-de-loop and die. Repeat until you have enough lives.

Scrap Brain Teleport

On the last level (Scrap Brain), find the ledges that move right then left. Go to the left side of the wall and wait for the platform to move. As soon as it starts to move left, duck. You'll go through the wall. While here, press Left to teleport right and Right to teleport to the left.

Get all Emeralds

This cheat allows you to start at the First Level with all the Emeralds, and with lots of Continues. Use the Level Select cheat (see above) to get to the Special Zone. When you get the Emerald, and have entered into the First Zone, press Reset.<p>

Use the Level Select cheat to get to the Special Zone again. When you get the next Emerald, and have entered the First Zone, press Reset again.<p>

When you have all the Emeralds, continue on with the first level. You get to keep the Emeralds and the Continues accumulated so far.
