Arduino 8-bit Computer

The emulator  now lets code access the SD card using I/O instructions. One of these instructions tells the Arduino to load a binary file into the emulated memory. This is nice, however the memory array is stored in RAM, so it is very limited in size. I will likely switch to using flash instead.

I was able to blink the LED on pin 13 using my emulator and Z80 compatible op-codes.
