This lib allows to create (and port easily) code that can run on your computer and a calc just by using the corresponding makefile.
It's designed for Casio's Graph calculators, fxlib is reimplemented for linux. You need the NESSCASDK to use it, casio's headers and a cross-compiler are requiered too.
A lot is left to do (Print, Timers, test ML, Fixing calc target, [...]) but it's enough to run Spassus2. 3Pin serial emulation is supported by using network sockets and a server, USB will come too.
