two buttons equals one input
So on my arcade I only have 4 buttons for inputs (plus joystick) per person. Some fighting games require 6 buttons. So my thought is to re map the buttons .
button 1= hotkey
button 2= input 1
button 3= input 2
button 4= input 3
button 2 + button 1 = input 4
button 3 + button 1 = input 5
button 4 + button 1= input 6
But i can't seem to get that to work when I hit tab while running mame2003
I am also pulling up retro arch config stuff, but That is a bit confusing to me. Any suggestions?

@ironj679 That feature is supported in lr-fbalpha. https://retropie.org.uk/docs/lr-fbalpha/#button-rebinding
@dudleydes Well, I can't seem to get it to work. I pull up the quick menu. (looks a lot like retroarch) and i can't get two buttons to act as one input.
Is there a way to access a FBA menu? or is it using the retroarch interface? Also, I could get a "test" screen up. But this looks like I am just testing input and not actually re mapping.
@ironj679 Just to clarify, you are using lr-fbalpha. The feature you are looking for isn't available in lr-mame2003, only lr-fbalpha.
@dudleydes Correct, to be straigt up honest. This is my first time trying to configurelr-fbalpha. I maybe doing this wrong. But I have been triggering the menus from in game. I can easily bring up the retroarch quick menu. Then I can bring up a game test menu. I spent about 3 hours of googling and trying things out with lr-fbalpha. With no luck of a menu in the software. My current theory is one has to edit the config file manually. where alt=301 or something like that. That quickly got dizzying, and I decided to stop the efforts for the night.
@ironj679 From the
Quick Menuin the RGUI, select
Options, if you scroll down you should see entries as below:
You can then define your button for the combo
P1 Buttons AB, for example, using the D-pad left and right to make your selection. Your changes should be saved when you exit lr-fbalpha.
@dudleydes oh my gosh! Right there! Thanks so much!!
