opcodes_cb.c -> This file executes the CB PREFIX opcodes.
When you find the CB opcode, it means that you must fetch another
byte from memory and treat it as a new opcode with different
meaning than the single-byte opcodes. This is a common way to extend
the number of opcodes (8 bits of instruction word = just 256 opcodes)
and it's called an OPCODE PREFIX (now we have another 256 new opcodes
by using this trick).
