Gameboy 4-in-1 is the sequel to, you guessed it, Gameboy 3-in-1.
Mario travels to a long lost pyramid to discover the treasure of the great god GAEMBOIPAYER. Upon discovering a dusty old Gameboy, Mario settles down to play it.
In May 2005 Mario Gamer, having just played Gameboy 3-in-1, contacted Delichanicho for a sequal. He was all for it and production started right away. The game was split in half and Delichanicho took two mini-games while Mario Gamer tackled everything else.
In July 2005, production almost completely stopped. Mario Gamer had resumed work on Mario Kart: Beanbean Circuit and Delichanicho had life catch up with him. By August Delichanicho finished his second game and left most of the rest up to Mario Gamer. Mario Gamer, never happy with one project switched back and forth for two years.
On December 15th, 2006 Delichanicho signed off the internet for good, unknown to Mario Gamer. Mario Gamer continued the project until it was finished and wished Delichan the best of luck. As of March 2007, Yoshiman jumped aboard and has continued to help out the project with coding. On March 26, 2007, two years after it was started, the game was finally released
