Fourth generation of video game consoles
Nintendo executives were initially reluctant to design a new system, but as the market transitioned to the newer hardware, Nintendo saw the erosion of the commanding market share it had built up with the Nintendo Entertainment System. Nintendo's fourth-generation console, the Super Famicom, was released in Japan on November 21, 1990; Nintendo's initial shipment of 300,000 units sold out within hours. The machine reached North America as the Super Nintendo Entertainment System on August 23, 1991, and Europe and Australia in April 1992.
SNK
In response to strong sales of the company's NES ports, SNK began to dabble in the development of original software designed specifically for the NES console. Two games came out of this effort: "Baseball Stars" (1989) and "Crystalis" (1990) (known as "God Slayer" in Japan). 1989 also marked the release of two new home video game consoles in North America: the Sega Genesis and NEC's joint project with Hudson Soft, the TurboGrafx-16. Nintendo followed suit with a new system in 1991, the Super NES. Rather than become involved in the early 90s system wars, SNK Corporation in Japan, along with SNK Corporation of America, chose to refocus its efforts on the arcade market, leaving other third parties, such as Romstar and Takara, to license and port SNK's properties to the various home consoles of the time with help from SNK's American home entertainment division. With console ports mainly being handled outside the company, it moved on to developing SNK branded arcade equipment. SNK also licensed Tiger Electronics to market handheld electronic games from some of its brands.
