G.I. Joe (NES)

G.I. Joe is a platformer based on the long-running line of Hasbro toys. YO, JOE!

Secret Passwords
The first three passwords start you out at the beginning of the game with Duke at the maximum level. The last one starts you directly at the "Congratulations!" screen. In the sound test, press Up and Down to select between music and sound effects, Left and Right to change the values, and A to play them.

CHR Viewer


Enable Game Genie code, then go to the Password screen and enter the password for the Sound Test. You'll be taken to the CHR Viewer instead. Here's what the controls do:

Stage Select


Enter Game Genie code, then choose the Password option on the title screen. Not only can you select the stage, you can also select different parts of the stage as well. Once you select your team members, you'll start the selected level.

NOTE: Selecting parts 3-5 of Stage 6 will crash the game after the boss cutscene, as they don't exist.

Disabled Debug Options
A couple of debugging options can be re-enabled with Game Genie code. During gameplay, you can do the following:
 * Left + A + B - Automatically finish the current level.
 * Right + A + B - Instantly kill your current character.
