Do you want over 60 lives or even more? If you just follow this simple cheat you could get
99 lives. Do the level select and enter the debug code. Then select the level "Aquatic
Ruin". It doesen't matter what act it is. Then you start putting them like crazy. Kill
them and you could get lots of lives. I made 188 lives by doing that!!!!!

use the game genie code APCA-AAEL and go in dheat egg use the debug mode, trasform into
super sonic,create a teleport box,now tails are super tails, trasform into super sonic
again. now the game his real fun!!!!

use debug mode and super sonic cheat go to any zone and place 50 rings and turn into
supersonic then u dont have to jusp to attack boss (you've gotta be sonic or sonic and
tails + it wont work with final boss) enjoy ) D

after the sega logo about to go away press start over and over again 'till the title
screen appiers

Do the level select and then enter the debug code. Select any stage with Tails in it. Do
the spin dash and then place a lot of baddies on Tails. Your lives will increase very
quickly and if you carry on your amount could be over 200!

You put the level select and choose any level.Next put in the debug code.Then press
'START' to pause.Then you press 'A' to reset. When Sonic and Miles(Tails) appear, hold 'A'
and choose 2-Player V.S.

Note:
Super Sonic will NOT work.

Activate debug mode and super sonic code. Go to any level with no boss. Now when you see
the sign (as super sonic) turn debug on and pass the sign. Sonic will glow(on the sign)
note: the sign will be glowing as long as you're in debug mode. Also if you go super when
you pass the sign it'll glow for 1 second. sometimes  if you pass through the level with
debug the sign will be an inactive bunch of springs

sonic 2 est un jeu a terminer sans cheat. c est vraiment dommage d utiliser des code pour
en venir a bout

use the game genie the code is ACZT-CACN use the debug mode end use the ashura glitch jump
 end you are trasform super ashura (get 50 ring but you are  freze use the debug mode and
you can control super ashura) good loock!

go to emerald hill zone 1 find the invincible TV and trasform into super knukles now is
hyper knukles!

2 do this u must hav debug & lvl select active.Go 2 Sky Chase, & activate the capsule (the
thing that looks like messed-up item boxes) then jump on it.Itll skip Sky Chase
altogether, then bring u 2 Wing Fortress at night. Have fun!!!!!!!!!!!!!!!!!

Get 50 ring then turn super Sonic.Then get the tv box.Now you are yellow Sonic.

Two Tails: Enter the level select and debug codes, then go to the Sky Chase level. Using
debug mode, create a transfer box and break it open. When you hear Sonic die press B to
enter debug mode again. Move the cursor up until you see Tails and exit debug mode. To
finish, jump and you'll have two Tails

To do this just enter debug mode and get to the thing that looks like messed up machinery.
Place it, then jump on it. It one of thoe things after a boss. 

NOTE: This will not work for the Sky Chase or Death Egg zones.
