In the recent versions of mame, the output system has changed.  To use apps built with the old system, please set "outputs" to "windows" in the mame.ini  Thanks!

Please Sticky this thread.

The MAME Windows output system sends commands to control the hardware on the original arcade cabinet that was controlled by commands from the original game PCB.

Examples of this include the Q*bert knocker, the flashing start button LED after adding a coin in Dig Dug (0:55-1:00), and lighting up the selected mission on the Lunar Lander Mission Control Panel.

Q*bert knocker


Dig Dug


Lunar Lander


    NOTE: This should not be confused with using LEDBlinky and "controls.ini" to light RGB LED buttons.  That is an external process not controlled by MAME because the original cabinets did not have RGB LED buttons.

There are two five important questions that need to be answered:

  1. Which version of MAME broke the old output system?  0.170
(so people with earlier versions know that they can disregard this post)

  2. Which version of MAME did the old output system start working again?  0.176 (?)
(so people know that they need to upgrade to that version or newer to use the old output system)

  3. How do I use the old output system with MAME 0.176 and later?
Just set the following in mame.ini:

Code: [Select]
#
# OSD OUTPUT OPTIONS
#
output                    windows

  4. Which version of MAME added the new Windows output system?  Headkaze's patch was added in 0.175.

  5. Which version of MAME has the new Windows output system working?  To be determined.
(As mentioned here there is still testing to do and further patches to implement and software developers will need to rewrite their .DLL library files to work with the new system)

EDIT: Added probable version #s.
EDIT 2: Added more questions and examples.

I'm not sure.  The changes were never documented, so we are just stumbling upon answers.  I'll download a few versions tomorrow and see if I can figure it out.

Thanks, Howard.   :cheers:

EDIT: I think I found a good starting point in the LEDBlinky thread.
As of mame .170 the output system is broken and LEDBlinky can't detect any mame output events. A patch has been submitted and implemented as of .176 but the interface library (between LEDBlinky and mame) is still in the process of getting updated.
