Star Fox (Starwing in Europe) is a on-rail shooter developed by Argonaut Software and Nintendo EAD, published in 1993 for the Super Nintendo. Argonaut worked closely with Nintendo during the early years of the NES and SNES. They developed a Star Fox prototype on the NES, initially codenamed “NesGlider”, which was inspired by their earlier 8-bit game Starglider, and then ported this prototype to the SNES.
Programmer Jez San told Nintendo that this was as good as it could get unless they were allowed to design custom hardware to make the SNES better at 3D. Nintendo assented to this, and San hired chip designers to make the Super FX chip, the first 3D graphics accelerator in a consumer product. [Info from Wikipedia]
Megalol found some Star Fox beta screens in Nintendo Power magazine from Jan 1993, in which we can notice a completely different (and awesome) beta title screen!
Originally a sequel titled Star Fox 2 was in the works for the Super Nintendo, but it was never released, though a handful of ROM dumps at various stages of its development were leaked onto the internet.
Thanks to Jason for the english corrections!
