As far as I can see, it does not implement POSIX compatible I/O routines,
which is a problem as I see it, because that means that cc65 would need that,
too, and not only the low level routines but also the hig level stuff
(fopen/fread/...) will be platform dependent.

If you have a recent snapshot, you may want to have a look at the header file
include/modload.h. It exports the necessary structures and functions to load
modules at runtime. The libsrc/c64 directory contains a graphics driver for
320x200x2 graphics mode, just have a look at the makefile to see how it is
translated and linked. There's a problem however: Since module loading needs
disk I/O, and disk I/O is not available for the CBMs, there will no longer be
loadable modules for the CBMs as soon as I remove the dirty hack I'm currently
using.

Yes, I've also had some ideas for games. Writing a simple pacman or so
shouldn't be too much work. But since I'm already way behind schedule with all
my other projects, I'm glad I never started:-)
