A three-year-old Nintendo 3DS game from a defunct Japanese studio has seen an unlikely boost up the sales charts, as it was claimed today that the game contains an exploit that allows for homebrew on the handheld device. A group of coders are on the cusp of releasing a homebrew channel for the Nintendo 3DS this weekend, which they say will allow 3DS owners to potentially utilize unauthorized apps on the device. And the exploit relies on a rather strange condition — you need to have a retail copy of AQ Interactive’s 2011 release Cubic Ninja plugged into your 3DS for the homebrew download to work. Since revealing this morning that Cubic Ninja is part of the process, sales of the game have rocketed, to the point that the game is, at the time of writing, sitting alongside titles like Dragon Age: Inquisition and Little Big Planet 3 in Amazon’s top selling charts. It’s unclear whether the game’s original developer AQ Interactive can do anything about this exploit. The company merged with Marvelous Entertainment and Liveware back in 2011, with Marvelous essentially enveloping the two other companies.
