I finally got the blink sketch running.

To get the blink sketch up and running in the Emulator, I had to get the CPU, Memory Mapper, GPIOs, and the timer overflow/compare IRQs working.

The IRQ and "micros" function use SRAM 0x0007~0x000A as a 32bit timer.

After all that fun stuff, I had an alternating bit in the PORTB register.
