For those who remember some of the bugs that were found in the original version of The Legend of Zelda: Ocarina of Time, Nintendo decided that it'd be bet if you could still put that knowledge to use for the Nintendo 3DS version.
In the latest "Iwata Asks", Nintendo's president spoke to the team responsible for the remake, Grezzo. They give insight into how they wanted to preserve the bugs that were present in the original Nintendo 64 Cartridge.
Shun Moriya, a Grezzo programmer said, "It wouldn't be fun if your friends couldn't say, 'Do you know about this?' So we left them in if they didn't cause any trouble and were beneficial."
"If something simply could not be allowed to stand, we begrudgingly fixed it, so some bugs don't appear, but we left in as many as we could, so people will grin over that."
The only downside is that the development team didn't mention what the bugs actually were. Seems like the challenge now is to find out what these bugs are.
