   Sonic the Hedgehog


Note: These codes are for version "USA, Europe" (REV00).


ATBT-AA32
Master code (use if you get a blank/red screen).


 *** NEW CODES ***


9JKT-B98J
Pause the game to enable debugger.  When you unpause, press B to activate
debugger, press A to cycle thru objects, press directional pad to move
objects around, press C to place objects, press B to play your new level.
You'll have infinite time, and invincibility.


BEKT-B78J
Pause the game to enable debugger (alternate version).  When you unpause, you'll
be a ring and can move anywhere in the level using the directional pad.  Press
A to cycle thru objects, press C to place objects, press B to exit debugger and
return to normal game-play.  You'll need to pause the game again if you want to
re-enter the debugger.  Also, you won't have infinite time or invincibility like
the other code.  Also works on special stages and makes it very easy to get the 
emerald.


HASA-SEXE +
FYSA-S75G
Pause the game to become invincible.  Enemies will die when they touch you. 
Invincibility will only last for one level, so you'll need to press Start again 
if you want invincibility for the next level. You'll also need to re-enable
invincibility if you lose a life, or if you pick-up another invincibility 
(from a TV, etc).


ATKT-AA8Y +
CAKT-AAHE
Pause the game and press A to play special/bonus stages.  Also (while paused),
holding B while pressing the directional pad will make Sonic move in slow motion,
and tapping the C button will make Sonic move one frame at a time.


ATKT-AA8Y +
DAKT-AAHE
Pause the game and press A to see ending sequence and credits.  Also (while 
paused), holding B while pressing the directional pad will make Sonic move in 
slow motion, and tapping the C button will make Sonic move one frame at a time.

DJKT-AN94
Pause the game and press A, B, or C for different cheats.  A = invincibility.
B = add 10 rings and an extra life.  C = add 10 rings.  Note that you won't see
the extra items until you pick up a ring, or lose a life, but you DO get them.
Also, the invincibility needs to be re-enabled if you lose a life, finish a 
level, or if you pick up another invincibility (from a TV, etc).

6TLA-AA28
Pause the game and press A for invincibility, or press B or C to add 10 rings to
your total.  Can repeat for more rings, but if you go over 100, you won't get
your extra life until you collect a ring while playing.  Also, the invincibility
needs to be re-enabled if you lose a life, finish a level, or if you pick up
another invincibility (from a TV, etc).

DTKT-AN94
Pause the game and press A, B, or C for different effects.  A = Activates
debugger.  B = Increases Sonic's top speed and acceleration.  C = Increases
acceleration only.  If you press A to activate the debugger, you'll be a ring 
and can move anywhere on the level.  Press A to cycle thru items, press C to 
place the items, and press B to exit debugger and try out your new level.  The 
top speed and acceleration will only last until you die or finish the level, but
you can simply re-enable it whenever you want.


RG1T-C61E
Invincibility (walk thru enemies and enemy fire).  Can still collect all items.
Can combine with other partial invincibility code (BL1T-CA3Y).


BL1T-CA3Y
Invincibility (partial).  Enemies die when they touch you, but enemy fire can
still hurt you.  Can combine with other Invincibility code (RG1T-C61E).


FMHA-AA90
Protection from spikes.


RH7T-A60A
Don't die when crushed by moving pillars. 


RZDA-C6ZT
Don't fall when you walk off ledges (Walk on air).  Press Jump to drop down.
Note that this code can sometimes cause Sonic to be slightly below ground level,
but can be easily fixed by pressing Jump.  If you have problems getting thru
the double "S" tubes on the first level, just slow Sonic down after the first 
tube so you enter the second tube slower.


AD7A-AA88
Walk thru rocks, spikes, walls (some), springs, etc.  Note that you won't be
able to use springs.


AL9T-CA3N
Touching the red "Goal" markers in the Special/bonus Stages won't make you exit.


CBDA-AAGG
Special/bonus stages rotate slower.  Code must be turned on before you enter the
stage.


ABDA-AAGG
Special/bonus stages don't rotate at all.  May make it impossible to get to
some areas, but a lot of fun to use.  Code must be turned on before you enter 
the stage.


AG8A-CAEE +
ABDA-AAGG
Special/bonus stages don't rotate at all, and you'll have high moon jump with
super slow moon descent.  Makes it easier to get the emerald and rings.  Code 
must be turned on before you enter the special/bonus stage.  Moon jump only works
in the special/bonus stages.


RHDT-C6TR
Don't die when timer reaches 10 minutes.


RHDT-C6VJ
Always get 5000, 10000, or 50000 Time Bonus points at the end of levels.  


SDDT-CAAY
Timer runs at half speed (2x slower than normal).


8DDT-CAAY
Timer runs at one quarter speed (4x slower than normal).


ACSA-AACJ
Always get the giant ring at the end of the level (for the special/bonus stage).



 Old Codes...

Infinite lives (alternate code).


GLRT-AADY
Ring count goes to 50 after getting hit.  You must have at least one ring.


NRRT-AADY
Ring count goes to 99 after getting hit.  You must have at least one ring.

game after you enter the codes below.


AE2T-AAAL
Enable Debugger!  Press the A, B, or C buttons for all
kinds of cool effects!  You can design your own level by

You can combine the "Enable Debugger" code above with
the "Start on level" codes below to let you use the
Debugger on any level you want.


NOTE:

(or any act) you want.  If you want to change the level
you start on, alter the 6th digit.  If you want to

alter the 2nd digit.
