I found the old thread for disabling the game warnings, but it doesn't work with the newer source.
Anyone know of where I can find the source that changes this?
(Probally no more than 3 or 4 lines of code, I just don't know where to start
)
Skip_warnings exists in both mame.h and mame.c in the straight source code,
but the option doesn't work from mame.ini or the command line.

Actually only one line will do it.

You need to enable the skip_warnings option. To do this, add the following line to your src\windows\config.c file:
{ "skip_warnings", NULL, rc_bool, &options.skip_warnings, "0", 0, 0, NULL, "skip warnings" },
Add it where the other command line options are set up.
Or you can use my BuddaMAME binary which has this option compiled in. Version 0.92 will be out soon.
