Cubic Ninja was a mostly-forgotten 3DS game released in 2011, at least until a hacker figured out a way to use the game to crack the 3DS itself, allowing the use of homebrew applications and emulators. The price of the game has since skyrocketed in the aftermarket, and it looks like GameStop is getting in on the action.
The game is listed at at $19.99 for a new copy, which seems reasonable, but used copies of the game are going for $39.99, but "PoweUp Pro Rewards price" is only $35.99. Games used to crack systems are of course in demand right now, so why shouldn't GameStop cash in? The game was priced at $5 used as recently as Nov. 19, according to forum posts.
This isn't the first time the company has raised the priced on used games that are in high demand. GameStop priced "used" copies of Xenoblade Chronicles at $89.99, labeling it at "vintage" game.
"As always, our pricing for these games is competitive and is based on current market value driven by supply and demand," GameStop's statement explained. "PowerUp Pro members always receive a 10 percent discount and earn PUR points on pre-owned purchases."
Nintendo has pulled the game from the e-shop, meaning physical copies are the only way you can attempt the exploit. This may not last forever, though.
"I've already been talking about this for a couple of months, so it's possible they may have figured out what I've been doing," Jordan Rabet, who found the exploit, told Eurogamer. "It's just a vulnerability in a game to access a vulnerability in the system firmware. All they'd really need to do is patch the firmware, and then the game doesn't even matter."
