a) you shouldnt be linking to atmos.lib at all, this lib is for the oric, not 
for the nes.
b) you have to create a static module from the nes joystick driver and link 
that (look here: http://www.cc65.org/snapshot-doc/co65-4.html), you can not 
load it - because there is no external mass storage to load it from in the 
first place =P
c) i know for a fact that this nes joystickdriver works... i wrote it (*g*), 
used it in my contiki port, and also some other guy tested it on a real nes.
