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.
