// Mapper top level selection
// Notes by Kitrinx:
// This module uses bidirectional ports to handle the data out of each mapper.
// Although FPGA's do not use bidirectional wiring internally, the alternative is
// creating a tenticle-monster of wires for each mapper, and muxing them all together.
// As it stands, the compiler will efficiently do it for us with much more readable and
// manageable code if we do it this way, and since not more than one mapper can be active
// at a time, there will be no conflicts.

// PRG = 0....
