Bomberman Hero is an action-adventure game released for the Nintendo 64, featuring Bomber Star as its main setting. The game includes three secret levels that can be accessed by using a Joycard 64 controller, which unlocks a Bonus option in the main menu. Players can alternatively unlock these levels by rapidly pressing the Start button upon startup. The unlock is temporary and resets upon rebooting the game.
"In Bomberman Hero, Bomber Star is the setting of three secret levels. Hudson has a history of awarding players with additional content when their special controller for a console was connected, and this was a similar case. If a player used a Joycard 64 controller, a new option called "Bonus" would appear on the main menu.
The Hudson controller is supposed to be used with the turbo function on the start button to access the levels. However, the controller is not required since the player can simply mash the button as fast as possible and unlock the content the same way. In a nutshell, if the player presses the Start button as fast as possible after turning on the game, it should be able to unlock the secret levels.
Some players find this difficult while others can do it with ease. The option is lost when the game is reset and there are no other requirements to reach the secret levels." https://bomberman.fandom.com/wiki/Bomber_Star
This hack permanently unlocks the Bonus levels without the need to use a turbo controller or mash the start button.
