Hey !

How to the TSCP chess engine had me ported in this chess application [wiibrew.org] since it uses the ftime function in the original code

// get_ms() returns the milliseconds elapsed since midnight,
//   January 1, 1970. 

#include 
BOOL ftime_ok = FALSE;  // does ftime return milliseconds?
int get_ms()
{
	struct timeb timebuffer;
	ftime(&timebuffer);
	if (timebuffer.millitm != 0)
		ftime_ok = TRUE;
	return (timebuffer.time * 1000) + timebuffer.millitm;
}

Ported source code, explanation of a workaround, or how to get the timestamp on libogc is appreciated

I guess you want "gettimeofday":

int getTime()
{
    struct timeval tv;
    gettimeofday(&tv, NULL);
    return tv.tv_sec * 1000 + tv.tv_usec / 1000;
}

Which is very portable, as it is a POSIX function found in Linux, MacOS, MinGW library for windows and the Wii.

tanks alot !
