 Treasure began to develop Mischief Makers in mid 1995 . At the time , they knew little about the Nintendo 64 's final technical specifications , graphics implementation , and development kit , but were nevertheless interested in the console and its improved " pixel quality " . Historically , Treasure developed games exclusively for Sega consoles , which made Mischief Makers their first release for a Nintendo console . Bringing Mischief Makers to the Nintendo 64 was a hardware @-@ based decision : the Nintendo 64 's cartridges were more expensive than CD @-@ ROMs , but they loaded data instantly and were thus more conducive for action games such as Mischief Makers . However , Treasure CEO Masato Maegawa said that development for the Nintendo 64 had a harsher learning curve than even the Sega Saturn . Other than the special attention required to build a single boss in 3D , the team did not use features specific to the Nintendo 64 hardware .
