One of the shortcomings of the Nintendo Entertainment System
(NES) is that it was designed in 1983 for the Japanese market, and
it wasn't deemed important to have the system be able to access
more than 40 KB of ROM (read only memory, data on the cartridge)
at any given time. By 1985, the cost of ROM chips decreased dramatically,
and it was feasible to include more than 40 KB of memory in a game.
To do so, developers added the "Memory Mapper Controller" or
mapper. It's an additional chip added to the cartridge that allows
the cartridge to switch between different sections of memory, to
let the NES access more than 40 KB of data. Most of the time, if
a game doesn't work in vNES, it's because of an issue with emulating
the mapper correctly.
