ROM Information

BoxBoy! is a puzzle-platform game developed by HAL Laboratory and published by Nintendo for the Nintendo 3DS handheld console. Players control Qbby, a square-shaped character who can produce a string of connected boxes. The boxes are used to overcome obstacles in stages that Qbby must be guided through. The project plan for BoxBoy! was devised in 2011 by director Yasuhiro Mukae, although the game did not enter development until 2013. The core gameplay concept remained the same throughout the title’s development, however, changes were made to length of levels and the structure of the game.

Each set of stages was designed with a specific theme in mind with the intention of expanding the game’s depth by introducing new elements continuously. The game was released via the Nintendo eShop distribution service in Japan in January 2015, and worldwide in April 2015. A sequel, BoxBoxBoy!, was released for the Nintendo 3DS in 2016, with a third game, Bye-Bye BoxBoy!, in 2017. A fourth installment, BoxBoy! + BoxGirl!, was released for the Nintendo Switch in April 2019. BoxBoy! is a puzzle platform video game in which players control a square-shaped character named Qbby.

The goal of the game is to guide Qbby through a series of obstacle-filled stages that are divided into sets called worlds. Each world is focused on a particular gameplay theme; for example one world introduces stages that contain deadly lasers, and another introduces cranes for transporting Qbby around. The central gameplay mechanic is Qbby’s ability to create boxes and make use of them to clear the obstacles. Boxes are created one at a time as a connected string and the maximum number of boxes in a string varies between each stage.

Qbby can detach the string of boxes then push it to different positions. The boxes can be used to overcome obstacles, such as creating a bridge to pass bottomless pits or building staircases to reach higher platforms. Additionally, Qbby can keep the string of boxes attached to his body. He may then use the boxes as a shield to block hazards such as deadly lasers. He is also able to grapple onto ledges and pull himself up by retracting through the boxes. Creating a new string of boxes causes the previous string to disappear. If Qbby dies, he will respawn at a nearby checkpoint.

What if the ROM is encrypted?

If you find a ROM that's encrypted, you need to use the Batch CIA 3DS Decryptor, created by Matif.

The ROM isn't working correctly?

Not all games are fully compatible with Citra. If you do find a game that's not working, try using the latest PabloMK7 Citra fork, the continuation of Citra since its shutdown.
