The North American release of F-Zero X supposedly suffered from a three month delay due to Nintendo of America's then release policy of spacing the release of first-party games out evenly. Nintendo of America reserved the domain www.fzerox.com for the game's release.
The F-Zero X team was made up of several Wave Race 64 key programmers (including the lead programmer). To leave the field open for future expansion, Nintendo added 64DD features into F-Zero X that would allow for add-on disks such as track editors or course updates. The 64DD was never released in North America, so these features were never taken advantage of.
F-Zero X sold 56,457 copies during its first week of sale in Japan.
