I guess the question is why ES crashes - can you get the log file from /home/pi/.emulationstation/es_log.txt and post it here ?

As an alternative you could create soft/symbolic links from the roms folder on your two usb drives to the systems roms folder on RetroPie.

The command to do so would be.
ln -s file1 link1

An example of linking psx roms from usb drive to the psx roms folder on RetroPie

ln -s /media/usb/psx /home/pi/RetroPie/roms/psx

This will create a soft symbolic link of all the files in the specific folder.

Look at the file1 as the source and link1 as the destination and change them to the correct location of each folder.

This is what i have done and it works most of the time but sometimes it does not as it looks like the mount of the USB name changes when restarting the RPI and that breaks the soft links. This approach is great if you don't want the usbromservice to move everything and just want to keep only the roms on the USB drive.

Edit: I think that maybe by using both soft symbolic links and then make sure that the USB drive always will be mounted as ex. USB0 or Your USB Drive then it would work great.

@Demarco72 Which image did you use to install the system ? Can you be more specific about the controller/gamepad you use - maybe a product page/site ?

Some mouse-only games are still setup to use just controllers and not the attached mouse/keyboard when you use the WHDLoad version. Populous, for example. I don't know what i need to do to unset that, so I can't make any suggestion for you on this either (if it's the case).

My only other suggestion would be to disconnect your controllers before firing up an amiga game and/or switch USB ports so that your mouse and keyboard are on the lower port numbers (0 and 1).

I don't know which emulator are you using for N64 and on what system, but what you're looking for is described din the Docs.

@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
