Also a reminder that arcade games commonly shared a single set of controls, for example pacman. So player 2 actually uses player 1 inputs when it's their turn. There were also games that had distinct player controls such as tmnt or mortal kombat. It would help to specify the game your trying to play to determine if that plays any part in your issue.

@bram279b What mitu said plus... you should just be able to swap joystick ports with the controller. It's built into the base mapping if you're using a SNES style controller.

If not, it should be your "A" button, whatever that is. That should toggle.

Try it with an easier game like Bruce Lee. Use the virtual keyboard as well as the controller to make sure you have it setup correctly.

The Virtual Keyboard in lr-vice64 also has a button to press to toggle joysticks,

@rkoster whoops! Didn't know/see/look at that. Thanks for pointing it out.

Hopefully the Guru's get this one figured out. Fingers crossed.

@tmoe01 said in Issue launching ROMs:

... then goes black again before returning to Retropie.

Using the desktop is not supported on Raspbian/Raspberry Pi, start EmulationStation at boot (from the terminal) and not from a desktop session. More details how to configure that here.

@mitu Thanks I was pressing the wrong save lol

@billymild by default retropie uses the RGUI menu driver:

it sounds like you're talking about the XMB menu driver:
alt text

you could set it to the latter via https://retropie.org.uk/docs/Configuration-Editor/ -

advanced config configure libretro options all/retroarch.cfg menu_driver = xmb

note that RGUI is the menu that is referenced in all our docs, and may be more performant on low spec machines like Pis.

@pinho83 said in Controller priority on retroarch emulators:

I changed controller configuration for lr-snes9x and lr-pcsx_rearmed so I can use the two logitech (more confortable with shoulders and triggers) and works good. I connect Logitech only when I want to play snes or psx games.

How exactly did you do that ? If you configured it from RetroArch, using a control remaps, then you need to remove the remap.

@mitu would you recommend to install retroarch this way, or is it on ones own risk?

My recommendation is to wait so the RetroPie included script is updated with the new version. We apply some patches locally - to the upstream source - that are useful for RetroPie users and these patches need to be re-done and re-tested when a new version is released.

Then I have no idea. I routinely use a keyboard - without a hotkey set - and don't experience the behavior you're describing.

@mitu I got my screenshot the way you suggested:

flip back to dtoverlay=vc4-fkms-v3d in /boot/config.txt use raspi2png

Thanks!

@jedcooper Sorry, never got around to fixing it. My menu widgets are already disabled, but the issue persists. I'm assuming that it's a similar issue to the one people are reporting with widgets, but not sure what more to do with that information unfortunately.

My other approach.. has been to emulate SNES on my Wii, haha. For an unrelated matter, I'm getting a VGA666 board in the mail some time. I don't expect that it will make a difference with this particular issue, but I'll give it a try anyway and report back if it makes a difference.

@mrnoholster I don't think that they'll be implemented in lr-mame2016 any time soon.

As I said, you can install the mame emulator and try running the game with it - it's the same emulator you've seen running on PCs with the effects you mention.

@mitu i'm back if you're still here for some reason...
i tried again for the log.
here it is: https://pastebin.com/U96FjKBt

If you have a 4k TV, try setting the video resolution of your Raspberry Pi to 1080p - you can modify the /boot/config.txt file on the sdcard and set

hdmi_group=1 hdmi_mode=16

then reboot your Pi.

@mahoneyt944

Finally resolved this! Thanks for all the help.

For future people encountering this problem, the issue was the iPac Ultimate IO not playing well with the PS4 Gamepad I had plugged into it. I was using them simultaneously for setup and configuration. When I removed the PS4 Controller and only had the usb keyboard and the iPac plugged in it started to work just fine.

@nyvram from the distance: If your room audio has some API reachable from the RetroPie you may consider the scripting function for specific events (since ES v2.9.2). https://retropie.org.uk/docs/EmulationStation/#scripting

The event game-start passes two parameters to every script in the folder ~/.emulationstations/srcipts/game-start/: ROM and basename (easiest is to echo them in a test script to determine what they represent exactly.)

Or put your actions for the room audio in runcommand-onstart/-onend.

HTH

@dankcushions It worked, Thank you very much. Would you consider adding this information to the Docs?

@chuck_pierce said in screen_orientation in retroarch.cfg doesn't seem to work:

The video_rotation works like a champ (so my games play in the correct orientation), but the retroarch menu doesn't seem to be able to rotate. I've got a cocktail style machine and have the screen rotated 90 deg. I've tried values 1, 2, 3, and 4 with no changes to the retroarch menu.

that's right. this function is intended to rotate the GAME, not the whole session. it is working as intended. it looks like there's an outstanding issue to rotate the whole lot outside of X, that you could follow here: https://github.com/libretro/RetroArch/issues/6770

unfortunately the ability to rotate the entire session outside of X does not exist for pi4, as far as i know.
