Anti-Piracy


As with most games Konami published since 1990, this game features a copy-protection routine. It checks for the presence and integrity of the CHR bank containing the copyright and "KONAMI" tiles, the packed tilemap containing the string "© KONAMI 1990", the first byte of the JMP opcode that calls the routine that displays the copyright information on the screen, and the first byte of the JSR opcode that calls the protection routine itself.


If any test fails, the game removes all non-player sprites starting from level 2. This renders level 2 itself impassable, due to the removal of several rotating sprite platforms.


Easter Egg


Too Bad. There is nothing here!

At the title screen, entering the Konami Code (Up, Up, Down, Down, Left, Right, Left, Right, B, A) will give a tone for correct code entry. Pressing Start, however, gives you nothing more than a mocking message.











Japanese English
ざんねんでした。 なにもないよ~ん! Too bad. There's nothing here!

The program code may have been intended to have more than one cheat codes at once, but there is only one cheat entry left in the pointer table for the cheats, the rest were removed at some point. However, some coding for at least one more additional cheat flag exists in the game. Code PAVLSYAA will replace the easter cheat effect with this unused cheat, which will grant 50 extra lives instead at the start of the new game.



Stage Select

Using the Game Genie codes ZZSKYGSZ+NLVGAGEU+ZASKZKZA you can re-enable the stage select screen instead of the main menu.



Build Date


Present at the end of the PRG ROM:


V0.0890810

While the build date (August 10, 1989) is clear, why would they list it as Version 0.0...?
