Due to the way the NES handles games, each cartridge can have custom hardware, requiring code to handle each new hardware layout. Currently we have coded mappers 0 to 3, with only 0 and 1 having been tested in any capacity. Any cartridge layout which is not currently handled will error out. Thankfully, NesDev gives us details on various hardware layouts, found here.
Current listing of supported hardware layouts can be found here.
