This ZX Spectrum conversion of the 1987 scrolling hack and slash arcade game from Taito was developed by Icon Design and published by Imagine Software in 1988. And it’s not bad, but it’s not great either.
Super Monkey Ball Jr. is a conversion of the classic GameCube game by Sega. It was first released in North America in 2002, and in 2003 in Europe.
From what I can tell Super Monkey Ball Jr. was never released in Japan… That can’t be right… I thought the Japanese were (rightly) mad for Super Monkey Ball?!
