When Metal Gear Solid: Snake Eater 3D arrives on the 3DS later this year, it'll be the first game for the system to launch on a 4GB cart rather than Nintendo's 2GB standard.
The game's creative producer Yoshikazu Matsuhana told Eurogamer last week how Kojima Productions managed to persuade Nintendo to bend the rules for its forthcoming PlayStation 2 port.
"In the beginning, Nintendo did announce 2GB cartridges but the thing is, we're coming from a DVD format," he explained.
"Really on the PlayStation 2 at that point, even before we upped the resolution, it was taking up almost the full 4.7GB on the DVD. We really couldn't bring that down to two, so at the very beginning we spoke with Nintendo and told them we had this problem and asked if there was anything it could do to help us out.
"Luckily, Nintendo said that 2GB wasn't the hard limit and that eventually it was thinking of raising the size. We asked if we could be the first ones to do so and luckily they gave us the okay."
Konami hasn't pinned a firm release date on the game just yet, but has confirmed it will see the light of day before the year is out.
