For this particular version (0.103) I think you have to look in "mame.c". Look for "void run_machine_core(void)"
This page has instruction for disabling the nag screen that could be adobted for this version.

Thanks Razzer! I've done the specified change and am now on to recompiling using 'MAME Compiler 64'. It runs fine for 6 minutes, then it seems to have a problem when it is trying to compile 'input.c'. The compiling stops and I get this error in the compile output window:
Compiling src/windows/fronthlp.c...
Compiling src/windows/input.c...
src/windows/input.c: In function 'win_init_input':

mingw32-make: *** [obj/mame/windows/input.o] Error 1
I have not edited the file 'input.c' in any way, so what's going wrong?
