/*	
 *	interpreter.c WILL BE a tool which can be used to interpret 6502 machine code inline.
 *	Machine code is expected as hexadecimal of length 2 or 6, depending on the instruction.
 *	Note that zero-page addressing is not fully emulated yet; it will still address the zero-page
 	section of memory but the instructions still take an address of length 4.
	This will be fixed later when the whole system is functional.
 *	There are a few special characters which print debug information
		d		Prints main system information
		mXXXX	Prints contents of particular memory location
