even when FT uses a an non-TIR interfacing, most users pass that over for the TIR interfacing for its quality.

there is no monopoly (proven) and no proof of anti-competitive behaviour (that cry has been going on for 2 -3 years now)

elaborate that please... what means? now you are climbing on the glass.. what quality have TIR interface that don't have FT?? THEY JUST SEND FUC*ING DATA THROUGH A .DLL

and, for your information, this is the C++ source code to use Freetrack DLL

/************************************************************************
 *	freetrack_c_interface.c
 *	
 *  A simple command line application which reads the data from FreeTrack
 *	using the FreeTrackClient.dll interface.
 *
 *	Assumes that a copy of the FreeTrackClient.dll is in the same folder,
 *	thought this does not necessarily have to be the same folder as the

the red/bolded text are the coords... that is very easy to include in a game... OK?

dmn... i promised not reply to W_R posts but i had to do
