@mitu Thanks. Unfortunately, jstest gives me yet a third set of inputs different both from what event_diag and the other program told me. IT shows for my old fat PS3 controller:
(Axes): X, Y, Z, Rx, Ry, Rz

(Buttons): BtnA, BtnB, BtnX, BtnY, BtnL, BtnR, BtnL2, BtnR2, BtnSelect, BtnStart, BtnThumbL, BtnThumbR, null, null, null, null

It's anyone's guess which of those axes the dpad uses, and how the hackfile would interpret it, since even the latest event_diag still shows nothing for anything except the analog sticks...

I'm thinking event_diag just has trouble reading from these types of controllers, since it reads my arcade joystick and button sets, and my buffalo controller buttons, just fine.

You can choose a hotkey enable button when you configure your gamepad and this will set it also in RetroArch so you can trigger an action with 2 button combos - see https://retropie.org.uk/docs/Controller-Configuration/#hotkey.
However, this is an emulator feature (RetroArch) and not a global/general input configuration option that will work in any program (including EmulationStation).

@saga Are you flashing the image directly to the sdcard or via BerryBoot ? Skip BerryBoot and flash it directly. Using the image from retropie.org.uk/download will also get you a Raspi OS Lite basic installation with RetroPie already installed.

@xxdavidxx unexpectedly for myself, I noticed that the rewind now works after the update. excellent

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.
