VI. Reuse of Source Code
--------------------------

   This chapter might not apply to specific portions of MAME (e.g. CPU
   emulators) which bear different copyright notices.
   The source code cannot be used in a commercial product without the written
   authorization of the authors. Use in non-commercial products is allowed, and
   indeed encouraged.  If you use portions of the MAME source code in your
   program, however, you must make the full source code freely available as
   well.

   Usage of the _information_ contained in the source code is free for any use.
   However, given the amount of time and energy it took to collect this
   information, if you find new information we would appreciate if you made it
   freely available as well.
