The set of programs that you will be able to compile will be severly 
limited. There is no OS to speak of, so the only mode you will be able 
to use is the "base metal".  This means no file I/O.

If you ever plan to run the output on a real hardware, add an option to 
reserve memory addresses for memory mapped registers.

There is a 16-bit derivative of 6502, maybe you could target that instead?

In any case, good luck.  Sounds really cool!
