Hi we wrote a complete guide on how to setup both a spinner and a trackball at the same time, so that the configurations are persistent and will apply to a whole game folder.
The idea is to set up a default retroarch config for mame/fbneo that will configure one of these devices as the default mouse (for example, the trackball), and create then just a file for rom folders that will be spinner specific.

For example, you have a roms/mame folder -> all games in there will work with the trackball by default, thanks to the global default config. Then you have roms/mame/spinner then for this folder, you will have to generate a retroarch "content configuration file" that will apply just for this folder, and set the mouse_index to the one of the spinner.

Trap: the retroarch menu will not let you save mouse_index configs, but will create the config files. You will have to add manually a line with player1_mouse_index = 2 for example...

We wrote a detailed guide (in french, use deepl.com to translate) with screenshots, etc. And we use it on several Retropie arcade cabinet that we built, that have both trackball and spinner in the control panel.

@mitu I was overcomplicating the problem. Apparently I just needed to push the HDMI cable a little harder into the port. 🤣

The more you know. That probably should have been the first thing I tried, but thanks for the help!

@dteam Dammit, I spent four hours updating the damn thing yesterday :D

@viragored said in USB Audio almost working – what am I missing?:

The pop-up window box still reports "On-board audio disabled etc..." but basically it's all working :-)

That's ok, the Audio menu is meant to configure only the on-board audio, hence the message. External (USB/GPIO) sound cards are not supported.

I think you got the wrong vswap.wl6:

a6d901dfb455dfac96db5e4705837cdb vswap.wl6

The checksum above seems to indicate a file from the 3D Realms release, but the other files' checksums are from the GOG/Steam release. I tested with the GOG release and the game works fine.

@mitu said in Player 2 binds in Retroarch 4.7.1:

It's a common issue with 2player USB encoders when P1 is wired differently than P2.

Maybe this should be stickied. "Super Metroid has a 'run' button, and your 2-player arcade controls must be wired identically." Might save a lot of posts.

@fadangalini
Fixed the problem.
By putting KEY_#302 in place of where you would put BTN_THUMB for example, works.

Solved it

In case anyone else ever tries to do something like this and finds this post, the problem was this:
Somewhere along the line, something required to start up the ROM expected an interactive terminal, which is why it worked over SSH and locally, and even worked with running the PHP script from the terminal, but Nginx/Apache/another web server won't provide any interactive terminal.

It doesn't actually need any interactive terminal, so you can wrap the startup command inside a "script" command like this, to lie to it and trick it into believing it has an interactive terminal

<?php $command = '/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ snes "/home/pi/RetroPie/roms/snes/an-example-rom-obviously-not-the-real-one-but-lets-say-mario-or-something.sfc"'; $result = shell_exec("sudo -u pi script --return --quiet -c '".$command."' /dev/null"); ?>

And that does the trick and starts the game up from a PHP web panel

I just now did what you said and that solved my problem. Thanks a ton. You are a lifesaver!

@sirhenrythe5th
I think I solved it by disabling display_magnify in the .rc

Please note some games appear to have the wrong aspect. gdarius and gdarius2 seem to be vertical, but videos on youtube appear to show them 4:3. This is unrelated to the setting above I think. I don't know enough about stv games tbh.

@luckyluca I think when you update from source with scummvm now you get the latest version

@dankcushions said in Running out of MEM and SWAP when compiling lr-mame:

@johnodon yes, i pointed you towards the script earlier. however the script provides an informed guess rather than a cast-iron guarantee. normally it's enough.

lr-mame is in the experimental packages for a reason...

Gotcha. Thanks for all your help.

@dudleydes Hey there -- glad I found this. I've tried out your xboxdrv file that includes this snippet,and (EDIT) managed to map it to my Xbox controller after finding the right names for the analog sticks and whatnot. However, in Tron:Deadly Discs, I can no longer fire diagonally since the mimic-xpad setting kills the diagonal movements for the second stick. If I remove mimic-xpad, I get the diagonal disc throwing back, but the controls jam up and break if I try to map the disc throwing buttons to the fully enabled 8 directional R2 stick -- and weirdly, ONLY when I fire diagonally.

Anyone else have this issue?

@stavros7575 Please open a new topic and explain your problem, don't bump old topics.

@mitu said in Warning, Parsing error for "controller"::

@mth75 the parsing error thrown by joy2key should be fixed by https://github.com/RetroPie/RetroPie-Setup/pull/3370

The underlying problem seems to be the RetroArch's auto-config file being incorrectly generated by EmulationStation. Is you left analog joystick working in games ?

@mitu Thx mate, problem solved

Updates!

I have gotten somewhat of a picture to have display (IGNORE THE MESS 🤣)

https://i.imgur.com/uCDczXZ.jpeg

This was achieved using the following modelines in the config.txt

hdmi_ignore_edid=0xa5000080 config_hdmi_boost=4 hdmi_group=2 hdmi_mode=87 hdmi_force_mode=1 hdmi_timings=1024 0 48 104 152 768 0 3 4 23 0 0 0 60 0 88509090 1

It's still obviously very distorted but what is odd that the pixel clock I'm using, 88.5MHz was the only way to get some semblance of an image. However according to the manual for my display it should be a pixel clock of 64MHz for 1024x768 60hz (resolution I'm using rn) and a pixel clock of 108.18MHz for 1280x1024 60hz

Any reason why the pixel clock is so off? Is my code still wrong? Ultimately I think this will boil down into me opening up the CRT and messing with the sync pots but I'd like to avoid that if possible.

Any further guidance or help is greatly appreciated 😄.

@dankcushions Alright thank you already! I do know it's possible to wire it like that but im more worried to how some games will respond to it when trying to play solo. I guess I will keep it simple for my first build and just use 2 separate ones.
