Absolutely necessary are the linker configuration (platform.cfg) and the
startup code (crt0.s, assembled to platform.o). Provided that you have these
two files, you can write programs that run on the platform. You may use any of
the existing platforms as example, I'm usually suggesting the c16.

If you use peekpoke.h you don't need a header file. But there's already a
_6522.h header file does already exist, so a something like

        #include <_6522.h>
        #define VIA     (*(struct __6522*)0x2000)

will make the VIA addressable as pseudo struct at address $2000.

That's probably the most difficult part:-)

The current snapshots are quite stable, so I see no problem if you want to use
them. However, the idea behind the snapshots is that people use them and tell
me, if there are any problems. So if there are problems, please

    - recheck with the newest snapshot, and

    - if the problem persists, please notify me.

I'm not able to test code for 4+ source and 16 target platforms. Without
people doing the tests and giving feedback, cc65 cannot evolve. This sounds
obvious, but my experience says it is not.
