Stage Select and Player No Damage

You heard the man. Sufferin' Succotash! No wait, that was the other one...

All versions of the game feature a simple stage select cheat, accessed by pressing A, A, A, B, B, B, Select, Select, Select, A, Start at the title screen. Choose a level by pressing Up or Down, then press Start.

However, the Japanese version features two stage select cheats; the second one is accessed with Up, Right, Down, Left, Up, Right, Down, Left, B, A, Select, Select, Select, Start and has an additional "Player No Damage" option, which can be toggled by pressing Select.

Although the US and European versions normally have this option disabled, you can enable it by using the Game Genie code OESGKTPA (US) or OAXKVYPA (Europe).

Build Dates

An ID string listing the build version and date can be found at the end of the PRG ROM:


MAST means it's the "master" version, and the numbers represent the date. As a result, we can tell that this build was compiled on August 9, 1991. The dates are the same in all versions.

Unused Graphics


What appears to be a set of teeth, found in the same sprite bank as the chandeliers of Stage 6. These were likely meant for a trap similar to one in the final stage of the sequel.

What's left of an unknown enemy. The sprites can be found in the background graphics bank of Stage 4-3. The graphics bank of this enemy was probably repurposed into a background graphics bank.


Two unknown blocks, found in the graphics bank of Stage 1-3.


Unknown pillar graphics, found in the graphics bank of Stage 1-3.

TTA canonbank.png

Present in the graphics bank for the backgrounds of Stage 2-3 (pirate ship) are tiles for a cannon.

A reconstruction of the cannon. May not be 100% accurate.

TTA unknownbackground.png

Unused background graphics for Stage 5. Probably a reference to "The Persistence of Memory" by Salvador Dali, as the clock(?) seems to be hanging from a tree branch.

TTA Unused Slopes.png

Unused slope tiles found in Stage 5's graphics bank. They look like early or alternate graphics for the ramps in the 2nd section of the stage.


Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: The US version doesn't seem to have the anti-piracy routine, which (unfortunately) becomes the base of the many pirated versions.

As with most of the games Konami has published after 1990, this game features a copy-protection routine. At the start of the game, the partial CHR ROM checksum is calculated to ensure its consistency (for CHR banks $38-$3B, sum total of four 256-byte blocks at $0000, $0500, $0B80, and $0D00, which contain the graphics for the Konami logo and fonts for the copyright string), and a flag is clear if there's a consistency failure.

If the flag is clear, in the Japanese version when completing Level 3-3 will cause the game to loop back to the first level. In the international versions, completing the final level will cause the game to loop back to the first level instead of playing the ending sequence. However, if the flag is still set at the time of the final check (CHR test has passed or skipped), there is an additional summing of the first protection routine code in the PRG ROM. If this test is passed as well, then the program will continue its normal operation or else do a loop back to the first level as well.

Regional Differences

The Konami logo was redrawn for the European release.

Plucky appears miscolored in the ending if you defeat the final boss as him. His sprite was edited (removing the outline) and recolored to fix this for the Japanese and European releases.
