ROM Map

This is meant to visualize where all data in the rom is stored. Each bank is 16kb in size, and can be swapped in as needed. The only exception is the PRG section, which is always loaded. It contains library code that is always accessible, as well as banking code.

Any banks marked as unused are great targets for your own code. You can also move things from other banks into them by changing their associated PRG_BANK_TYPE define in the header file.
