Same error as before. I tried those changes. I'm not worry about it. There too many / and some others.

I think you're trying to treat it as a plugin when it's just a regular .lua file. I put robotron.lua directly in the plugins directory.

Then just

r = require "robotron"
r.start(4) -- give it a number from 1 to 4 for algorithm number


Bob-Z's version is basically the same changes.


https://github.com/Bob-Z/RandoMame/blob/main/bots_AI/robotron.lua

I fix it. I downloaded it wrong. Put all kind of crap in the file. Even my email for some reason. I downloaded it right this time with me log out of the website. That was so weird on what the website did. I was using the DownThemAll addon for the browser. All I had to do is to look for the download tab on the site. Anyway I solved the issue.

I didn't see the vectorkong on the list. https://github.com/10yard/vectorkong

For Ubuntu, Fedora and Nobara. (I tested this on these.)

Right click on the mame folder and then bring up the terminal. Paste this command from below and then hit enter to load it.

./mame dkong -plugin vectorkong -video opengl

For Windows.

mame dkong -plugin vectorkong -video opengl

How I get the Nibbler to work?

I keep getting the Maze1.lua missing error.

[mitchell@nobara-pc mame]$ ./mame -autoboot_script /home/mitchell/.mame/plugins/nibbler/nibbler.lua nibbler -w
Ignoring MAME exception: Error running autoboot script /home/mitchell/.mame/plugins/nibbler/nibbler.lua: runtime error
cannot open Maze1.lua: No such file or directory

Fatal error: Error running autoboot script /home/mitchell/.mame/plugins/nibbler/nibbler.lua: runtime error
cannot open Maze1.lua: No such file or directory

I even tried this.

./mame nibbler -console -window

r = require "nibbler" "Maze1"

=====================Edited

I got the SpaceZap working. I did on what Golden Child told me to do on the robotron.

Try putting the nibbler.lua and Maze*.lua files in your mame directory,
cd to your mame directory, launch mame

then

dofile("nibbler.lua")


plus you have to make a couple of changes to the nibbler.lua file:

-- Define the hardware interfaces we'll use
local cpu = manager.machine.devices[":maincpu"]
--local cpu = manager:machine().devices[":maincpu"]
local mem = cpu.spaces["program"]
--local ioport = manager:machine():ioport()
local ioport = manager.machine.ioport

Thank you. It's working now.

I applied your changes, but I'm getting the following error when trying to execute do.start()

[code[string "..."]:2: unexpected symbol near '.'[/code]

Can you show the complete console text (commands + result) when you try to run it as well as the edited code?

I'm not quite sure what do.start() would do

The commands for robotron were:

r = require "robotron"
r.start(4)

-- give it a number from 1 to 4 for algorithm number

I'm trying to get SpaceZap to work, not Robotron. do.start() is a typo, I meant r.start()
