@Romstar An update on this the game is working / Marbles are rolling as it should!!! FIXED that with physically swapping the GreenX1 & Yellow X2 respectively for both players on the Ultimarc Opti-Pac. However the Opti-Pac Designed from ultimarc doesn't work with their software so I can't reflash the inputs that aren't being utilized. On the bottom of the Opti-Pac is "Left" & "Right" buttons / or rather left click right click on a mouse... which is fine, but NO INPUTS for Coin ! This is how I have it wired in case any one else is using the same setup:

5v - RED
Ground - BLACK

Blue trackball even though considered player one on the left (*Intentionally goes to the P2 side of the Opti-PAC)

P2 X1 - Yellow
P2 X2 - Green
P2 Y1 - Blue
P2 Y2 - Purple

Red trackball (*Intentionally goes to the P1 side of the Opti-PAC)

P1 X1 - Yellow
P1 X2 - Green
P1 Y1 - Blue
P1 Y2 - Purple

Left P1 - Player 1 Start
Right P2 - Player 2 Start

(*also to note the original Marble Madness control panel the notches in the trackball face the bend / curve towards the front of the player, where as the flat end underneath on the trackballs face going away / the monitor.)

Still no way to hook up 5 "coin" as of now ... In theory I can daisy chain it to a start button but that would be on FREE-Play which I don't want. So CLOSE to getting this the way I need it to be!

Well I got it to work, but I just need a way to save the setting on restart. I went into RetroarchGUI Settings-Input-User 2 Binds and changed User 2 Device Index from disabled to Microsoft X-Box 360 pad. This makes my two player games work, but will not stick and changes back to disabled on exit. Is there something I can change in a config file?

How do I do this in advmame ? I'm confused as to where to input this text:

marble/input_map[p1_trackballx] mouse[1,x] -mouse[1,y]
marble/input_map[p1_trackbally] mouse[1,x] mouse[1,y]
marble/input_map[p2_trackballx] mouse[0,x] -mouse[0,y]
marble/input_map[p2_trackbally] mouse[0,x] mouse[0,y]

"advmame.rc" where is this file so I can locate and modify it using notepad++ and WinSCP ?!

Totally understood.
Thank you very much for your help, I really appreciate it a lot.

@luizsaluti Probably yes, but I would imagine that the actual release would be better installed from a Pi image instead. Things might change till then, but feel free to try out the branch on the Pi4.

@mitu THANK YOU VERY MUCH! you are the best!
With this advice you save me tons of hours.

@aatheronb I'm assuming that you're talking about EmulationStation, RetroPie's frontend? If so, see this thread.

This is indeed part of a safe shutdown circuit.
This pin needs to be HIGH while the raspberry pi is on and not change its state before shutdown process completes, because it drives the mosfet that provides power to the pi.
Thank you, I will try your script although I don't understand it.

@XionXero said in Controller Help Needed:

Just got my Raspberry Pi 3+ and a preloaded flash drive from amazon.

So, you don't use the official Retropie image? Third party images are not supported here, because they may differ from the official one and thus, may have problems which the official doesn't. If you haven't installed the official image, you should do so. (But don't forget to backup any data that you don't want to lose before that!)

Furthermore, if you bought Retropie, it's illegal and you were cheated by the seller, because the Retropie license forbids selling of any kind.

Sorry to put it that bluntly, but it is like it is. If you're already using the official image, just ignore this post. 😌

Somethink like this, but US based.

great thanx. so the 2 player must be the start button on the second controller.
perfect. so i have configured the buttons. but if i hit it, i cant play. so there must be an Option to set the which button is the 2 player mode button

what do you think of it.

Has anyone figured out how to use LEDspicer with MAME to automate which buttons are used per ROM? I have LEDspicer running but can not for the life of me figure this out.

@Jimi007 Yeah the zero is too slow for Amiga, it also struggled with 32X.

I found that out the hard way after setting up a "MicroMiggy" using one and only realised at the end that its too slow.

Yes, that one. And you're correct about the revision history. I didn't check that. I must have misremembered what was there.

@andymarham did you ever solve this? I have exactly the same issue...

Never mind, I didn't realize when I saved the python script it saved additional embedded formatting. I just had to download a straight text editor and it is working fine. Thank you.
