Set to **1** to build additional tools along with the emulator, including

**unidasm**, **chdman**, **romcmp**, and **srcclean**.
|

EMULATOR
|

Set to **0** along with **TOOLS=1** to build *only* the tools and not the
|

main MAME emulator itself.
|

When set to **0**, the main emulator target will not be created. This is
|

intended to be used in conjunction with setting **TOOLS** to **1** to build
|

the additional tools without building the emulator.
|

NO_OPENGL
|
||||
Set to **1** to disable building the OpenGL video output module.
