NES CPU Tests
-------------
These test most of the instruction behavior fairly thoroughly, including unofficial instructions. Failing instructions are listed by their opcode and name. Serious errors in basic opcodes might cause massive erroneous errors.

cpu.nes			Tests all instructions
official.nes	Tests official only

Most instructions are tested by setting many combinations of input values for registers, flags, and memory, running the instruction under test, then updating a running checksum with the resulting values. After trying all interesting input combinations, the checksum is compared with the correct one (what a NES gives) to find if the instruction passed.

This approach makes it very easy to write the tests, since the instructions don't have to be each coded for separately; instead, only the different addressing modes need separate tests.
