> Kirby's Dream Land was developed by Masahiro Sakurai of HAL Laboratory. Much of the programming was done on a Twin Famicom, a Nintendo-licensed console produced by Sharp Corporation that combined a Famicom and a Famicom Disk System in one unit. As the Twin Famicom did not have keyboard support, a trackball was used in tandem with an on-screen keyboard to input values; Sakurai described the process, which he assumed was "the way [game programming] was done" at the time, as similar to "using a lunchbox to make lunch."
