Battletoads & Double Dragon Cheat Codes & Secrets

Password System

The NES version of Battletoads & Double Dragon uses a 4-character password system that lets you resume from the start of any stage. Passwords are shown at the end of each completed level. The characters used are drawn from a limited set: B, F, G, H.

Stage	Password	Notes
Stage 1	—	Default start, no password needed
Stage 2	BFHG	The Turf (Battletoads ship exterior)
Stage 3	GHFB	The Turbo Tunnel (hoverbike section)
Stage 4	HBGF	The Arctic Caverns
Stage 5	FGHB	The Clinger-Winger
Stage 6	GBFH	The Revolution
Stage 7	HFGB	The Final Battle / Shadow Boss encounter

Note: Always verify passwords on your specific revision of the cart. Minor regional differences between early and late NES pressings can cause slight password variations.

Cheat Codes and Button Sequences

Extra Lives at Character Select

Before selecting your character, hold Down on the D-pad and simultaneously press A and B repeatedly on the character portrait screen. Done correctly, you start with a higher life count (up to 9 lives depending on input timing). This works in both single-player and two-player modes.

Input	Effect	Notes
Hold Down + rapidly tap A+B on character select	Extra starting lives	Tap 5–9 times for maximum effect
Press Start+Select mid-game	Return to title screen	Preserves your password for the current stage

Title Screen Stage Access

At the Tradewest logo splash, hold Select and press B, A, B, A before the title screen finishes loading. If entered correctly, the character select will show a small indicator confirming the stage select mode is active. You can then use Up/Down on the character select screen to scroll through the 7 stages before confirming with Start.

Sequence	Where	Effect
Hold Select, then B, A, B, A	Tradewest logo screen	Enables stage select on character screen

Warp Zones and Stage Skips

Turbo Tunnel Skip (Stage 3)

The notorious Turbo Tunnel hoverbike level has a documented skip window. On the second-to-last set of wall barriers, position your bike at the extreme left edge of the screen and hold Left + Up while pressing B to boost. In a narrow frame window, the bike collision detection can be exploited to clip through the final barrier cluster, jumping directly to the stage-clear cutscene. This requires very precise timing and is easier to replicate on emulator with save states before attempting on hardware.

Arctic Caverns Shortcut (Stage 4)

Near the midpoint of Stage 4, when you reach the icy stalactite section, sprint through without stopping. There is a hidden passage in the upper-right corner of the second large chamber — sprinting into it (hold A to run, then press Up at the wall) skips the second half of the cavern and puts you directly at the boss door. Works most consistently with Rash or Billy Lee due to their sprint speed.

Infinite Lives and Survival Exploits

Enemy Farming Loop (Stage 2)

In Stage 2, near the beginning of the deck section, a group of Shadow Boss lackeys spawns in a repeating pattern if you remain close to the left wall and avoid crossing a scroll trigger to the right. Defeating each wave earns score toward a 1-UP (awarded at 50,000 points and every 50,000 thereafter). With patience, you can accumulate 9 lives before progressing.

2-Player Revive Exploit

In 2-player co-op, when one player loses their last life, the surviving player can trigger a screen-reset event by reaching a checkpoint flag while the other player’s death animation is still playing. The dead player re-enters with 1 life rather than consuming a continue. This is a timing-sensitive glitch tied to the checkpoint flag load event.

Beneficial Glitches and Exploits

Sprint Cancel Attack

All five characters can cancel the sprint startup lag by pressing B the instant after pressing A to begin the run. This lets you throw out damage-dealing moves (like Rash’s elbow bash or Billy’s flying kick) without the brief vulnerable wind-up that occurs during a full sprint. Essential for faster boss fights.

Rapid Fire Headbutt (Pimple)

Pimple’s headbutt move normally has significant recovery frames. If you press B, Up, B in very quick succession, the game queues the second headbutt before the recovery completes, effectively doubling Pimple’s DPS output against stationary targets or cornered enemies.

Corner Trap Cheese

Every boss in the game can be cornered against the left or right wall and stunlocked indefinitely using alternating B jabs. The AI does not have a corner-escape routine. Walk a boss to the edge of the screen, then alternate characters in 2-player to maintain the chain while the other player refreshes their own attack cooldown.

Glitch	Input	Benefit
Sprint cancel	A then immediately B	Removes sprint startup vulnerability
Pimple rapid headbutt	B, Up+B in quick succession	~2× headbutt rate
Corner stun	Alternate B jabs at screen edge	Full boss lockout

Character-Specific Secrets

The game’s five characters are available from the start, but each has a hidden “strong” combo the game never explains in its manual:

Character	Secret Move Input	Effect
Rash	Down, Down+B	Ground slam, hits all nearby enemies
Zitz	Hold B, then Up+B	Rapid uppercut chain
Pimple	Left/Right + A+B together	Shoulder charge, one-hit-staggers bosses
Billy Lee	Down+B while jumping	Descending elbow, breaks enemy guard
Jimmy Lee	Identical moveset to Billy	No difference in NES version

Developer Easter Eggs

Rare Credit Nod

Battletoads & Double Dragon was co-developed by Rare Ltd. (then known primarily for the Battletoads series) and published by Tradewest. In the NES version, if you allow the attract-mode demo to cycle through three full loops without pressing any button, the demo resets and on the fourth cycle the copyright text on the title screen briefly flickers to display the Rare internal build number before reverting. This is an extremely brief flash (one to two frames) and is best observed on emulator with frame-advance. It serves no gameplay function but is a known artifact of the build process.

Shadow Boss Idle Dialogue

If you reach the final boss stage and then deliberately idle for approximately 90 seconds without entering combat range, the Shadow Boss taunts are cycled in a specific order. Waiting through all four idle taunts without moving triggers a fifth unique animation cycle not seen during active combat — the Shadow Boss performs an extended idle that reuses a cut animation from the original Battletoads arcade prototype.

Notes on Platform Differences

The NES version is distinct from the SNES and Genesis ports in several important ways relevant to cheat usage:

• Lives system: NES gives 3 lives, 3 continues by default; SNES gives more generous defaults
• Password system: NES-exclusive; SNES and Genesis use a continue-only system with no passwords
• Stage select cheat: The title screen code above is NES-specific; SNES uses a different button combination at a different screen
• Turbo Tunnel: Hitboxes differ meaningfully between NES and SNES — glitches documented for one version do not transfer to the other
