Entering the following will allow you to begin the game with all swords/equipment and all forms unlocked.
You will also begin as Hu-Man, this form will be lost if you transform.
On the continue screen, input:
WE5T ONE
for the first 7 characters, the rest of the characters remain as O. Make sure it's a ''5'' not an ''S''
As Hawk-Man return to the Mummys Tomb and travel all the way to the end where you would fall through the floor to fight the dragon. Don't fall through the floor, instead fly directly upwards and you will find a treasure room containing money and health.
Enter the following passwords at the Continue screen...
Sick of having to sit too close to your Sega Master system just so you can pause it, and sometimes accidentally causing problems by hitting the system too hard?
Simply plug in a second controller and sit it right next to you. When you need to pause, press up, down, left or right on the second controller and voila! Your pause menu, without having to touch the sometimes sensitive system!
Enter MJWH WC5TY3B XJR to go directly to the end of the game.
In the manual for the game there is a picture of the password screen in which the password is fully visible. Entering that code will allow you to play through the game with all the weapons/armor/shields and as the Hu-Man than you start the game as. If you enter any transform booth you will become Lizard-Man, and you can't change back to Hu-Man without reentering the code.
This is an update to the other Human code I posted.
On page 5 of the manual, there's a screen shot of the password screen. If you squint real hard you can make it out as:
3YGU PYZ ZY7K NRR
This will put you at the beginning of the game with every puece of armor, shield, and weapon. You will also be the Hu-Man-which is normally not availible after the opening sequence. If you use the change room in the town to change to the Lizard-Man form, you will be unable to switch back to the Hu-Man form.
