Entering Cheat Codes
To enter a cheat code, access the Options menu from the main screen. Scroll down to the password section and use the directional buttons to change the numerical values of the password. When you are finished, press "Start." The game will take you to a new screen if you entered the code correctly. When you use a cheat code for a normal level, the game will take you will first to the character select screen and then to the corresponding level. For Megazord levels, however, you will begin play automatically after entering the code.
Level Codes
The following level codes allow you to start the game in a level other than the first level. Enter 3847 for the second level, the industrial district that features Gnarly Gnome as the boss. The code 5113 starts you out in the third level, the sewer that features Eye Guy as the boss. Enter 3904 to access the fourth level, the motel where you fight the Genie boss. Enter 1970 to access the fifth level, the caves that feature the Dark Warrior as the boss.
Megazord Battles
The final levels of "Mighty Morphin' Power Rangers" feature a one-on-one battle between the Power Rangers in their giant battle robot, the Megazord, and a monster. Enter the code 8624 to access the sixth level and battle against the monster Mutitus at the waterfront. Enter the code 2596 to battle against the final boss, Cyclopsis, which you must defeat twice with one health bar in order to win. Before the battle with Mutitus, you must watch a cutscene of the Rangers summoning their Megazord and winning the battle against Cyclopsis. It allows you to watch the game's ending.
Two-Player Fighting Mode
The game has a secret two-player mode that allows players to reenact the game's Megazord battles with player one controlling the Megazord and player two controlling the monster. Enter the code 0411 to play as Megazord and Mutitus in two-player mode. Cyclopsis in the one-player game has two forms and two life bars. In two-player mode, however, you can choose only one or the other. Enter the code 1007 to play as Megazord and Cyclopsis in his first form and enter the code 1212 to play as Megazord and Cyclopsis in his second form.
