It's pretty easy to do this, and now that Bastian has given the ok to use his library functions we could have a working lynx target for cc65 very quickly.  There are functions in his library to access the cartridge...

I guess for the sake of cross-platformness you may could get some kind of file-io working, though with a system that is so different from the others it may not make any sense.  You will need to functions to grab data from the cartridge in any medium size game.

Bastian warned us that some registers in the lynx *have* to be written lo byte first.  Might this be a problem if we've written large structures to address the internal hardware of the lynx (how does cc65 write to addresses?)
