I've designed a universal control panel to play as many games as possible. I currently have the MALA hardware to control the individual game LEDS.
I would love to see a picture of your MaLa hardware installed and your Controls

The MALA Hardware is working great. All of my LED's are lighting up when I test them under the MALA Hardware configuration option. In the MALA game menu the assigned LED's are lighting up appropriately. However, I need to be able to override the default controls and assign specific LED's to be lit up for certain ROMS due to my keyboard layout.
Does anyone have any experience using MALA's LED Game Files option? Do the files you use for this option have to be named exactly like the ROM you are trying to configure the LED's for or is it just one big file which contains a listing of several ROMS that you are trying to control the LED's for? What is the syntax that these files need to follow? Finally, what file extension, if any, needs to be used?
Any help or suggestions to accomplish this task would be appreciated. Thanks.
OK.. I had not done that for a while so I had to test it myself.
So to overide how MaLa is handling the Led Lighting for Native MaLa hardware or Pacdrive support on a rom by rom basis:
You need to create a overide file for each rom you need to be custom assigned. I have attached a 'pengo' example. It is basically 1 line comma seperated text file. a '1' represents LED on. The First number (from left to right) represents whatever is wired up as LED 1 in the config/hardware tab. If no file is found for that Rom MaLa will handle it in the usally way (as most do)
If an invalid file is found no LEDS are lit. So use my attached example as a guide.
Also you have to tell MaLa what directory to find these files (whatever you like) . See pic Z1
THAT SHOULD WORK

Also
Did you you know that the LEDS can light on the fly if you have the a certain checkbox attached.See Pic z2. In my opinion the only reason you would not want that on is personal taste or you PC is too slow to handle it and it starts effecting scroll speed.
Have fun
