If so, how about hacking newlib/libc/stdio/vfprintf.c. Look for the string "(null)", and replace it with empty string and set the size variable to zero. On CVS version of newlib, it's in line 1033: cp = "(null)"; size = 6; Can't guarantee that this hack will not make your NDS goes kaboom though. :) -benny
