There are two included plugins that manipulate inputs:
See if you can work something out.

All right, I found "function lib:load_settings()" in autofire_save.lua which appears to be what I was looking for (identifying the machine buttons), so thanks for that!
Unfortunately, I'm seeing errors when attempting to require JSON from the console.
Code:
D:\MAME>mame64_247 mk -window -console -sound none
mame 0.247

[MAME]> local json = require('json')
[MAME]> print(json.stringify("{'test': 555}"))
error: [string "..."]:2: attempt to index a nil value (global 'json')
[MAME]>
Am I doing something wrong? Does "require" not work from the command line?

Each line you type on the console is effectively run as a function. This means that any local variables will only persist until the end of that line. The json variable you created no longer existed when you tried using it.

Thank you Vas!!
It seems I had a few issues there, overlooking "local" and also my JSON test was not the right syntax 
This works as intended.
Code:
json=require('json')
print(json.stringify("{'test':'555'}"))
