Due to Nintendo’s restrictions on file size, two popular downloadable titles won’t be happening on the Wii. Ever. At least in download form. Bionic Commando Rearmed and Super Street Fighter II Turbo HD Remix simply won’t fit within the file size restriction set by Nintendo for WiiWare releases. Christian Svensson laid out the reasons which include costs in downgrading the game and the file restrictions.
They could work as a retail release on a disc, but Capcom doesn’t see that as a viable alternative. On top of that, anything with “HD” in the title probably shouldn’t be downgraded in the first place. It’s missing the point otherwise.
