@joelkolb Wow! Thanks for the really detailed explanation!

@whoremoan I believe your post describes an issue I have also been struggling with for some time, but recently made some headway in diagnosing. One thing, though - you included ADVMAME in your list...I haven't encountered the problem with that emulator, but have with the Libretro emulators (LR-MAME2003, etc).

There have been some issues reported in GitHub for Retroarch describing this same problem. For example, see https://github.com/libretro/RetroArch/issues/10780. There is a fix available (https://github.com/libretro/RetroArch/pull/11471) which is not yet available in Retropie, but will probably make it in fairly soon.

In the mean time, one thing you can try (again, this would only be for the Libretro emulators) is to enable the "Game Focus" after entering a game, which usually defaults to the Scroll Lock key (yes, a keyboard would be needed, though I believe you can remap the key within the Retroarch on-screen menus).

EDIT: Though enabling Game Focus can be used as a workaround, after further testing / playing I discovered that using the "Grab Mouse Toggle" instead is often all that is needed (Game Focus locks down keyboard inputs, which may be too restrictive depending on the hardware). The Grab Mouse Toggle defaults to F11 (+ hotkey), but can be redefined in the retroarch.cfg file (input_grab_mouse_toggle = "j", is what I'm using). Grab Mouse does what it advertises, and makes the OS mouse pointer 'disappear' and not interfere with the game's mouse pointer.

@escc1986 said in Lightgun Question : How To Use Duel Wiimotes with Dolphenbar ?:

My Question is Could you use 2 Dolphen bars and use 2 wiimotes to play 2 player ligh gun games on the pi4 ... if so does any one know how to do it ?

I've never tried (I only have one bar) but I think that's how it is supposed to work. I suppose you use the bar in mode 2? This mode only supports one connected Wiimote. :(

or Could you use 2 wii motes on 1 bar ?

This would work in mode 4, right? This mode is used for the dolphin emulator, and I think it doesn't work with Retropie without proper drivers.

There is a link I found recently, where someone made a high-precision Wiimote "driver" that works with 4 IR LEDs around the TV set. I suppose that this works a little like the Sinden Gun, but I have not come around to try this. Maybe if you have the time and dedication you could try this. Maybe it even works with multipe Wiimotes, I don't know?!

Theory : im thinking but not certain , but maby i can have/enable duel mouse then it could work possibly ... but how do you enable duel mouse on retroarch on pi4 ?
for mame2003 games

As I said, I have never tried this. Maybe you can in a fist step try getting it to work with one Dolphin Bar (in mode 2) and a regular mouse?

@dankcushions and @mitu I deleted my roms, and uploaded them using a USB drive creating a retropie directory, and everything is working now. I'm not sure what the difference between using SFTP and the USB drive is, but it's working now. Thank you for your help, and have a great day!

Hello
What was the fix that you came up with. I'm getting the same error.

@lootchamoneytho I believe so, however it's how each game is setup . In the "mame tab menu" there is often (not always) an option (dip switch) to control the coin slots.

@neurocrash
I have the same problem with segmentation fault while running atari emulator.
I wrote two scripts:
1 - /home/pi/joyoffon.sh - turn off, wait 30 seconds, turn on controller
1-1.5 - this is my controller listed by lsusb -t

sudo echo '1-1.5' | sudo tee /sys/bus/usb/drivers/usb/unbind sleep 30 sudo echo '1-1.5' | sudo tee /sys/bus/usb/drivers/usb/bind

2 - /opt/retropie/configs/all/runcommand-onstart.sh
run joyoffon.sh only for atari emulator

echo "runcommand-onstart.sh" >&2 echo $1 >&2 if [[ $1 == *"atari"* ]]; then echo "This is atari - run script" >&2 /home/pi/joyoffon.sh & fi

After running atari game I have to wait until controller message appears.

@dreamcastkid opppsss !!! sorry lol

you're pretty close .. you forgot the "p" in Raspberry

but at least it's better than the 1st typo ;)

@mitu
No, it's not related to the build, it happens with vanilla retropie and vanilla raspberry os too.
One ugly workaround I found is copying the files to a fat32 system and back to ntfs on my Windows PC before copying them over via Samba.
The intermediary fat32 step gets rid of any permission issue they have.

@zodiark12 that's right. the retroarch menu could definitely be more intuitive in this regard but yes there's unobvious demarcation between options for the emulator core itself, and those of wider retroarch.

@clemsonteg It's been some time, but I found this post while trying to figure out how to hide the bootloader myself. For reference, I found the answer at RaspberryPi.org and set my DISABLE_HDMI=1 in order to prevent the display.

Noted in the URL above, this has only been an issue since the 2020-09-03 release of RPi OS as the behavior was changed to disregard the disable_splash flag. Hopefully this helps you out!

@ryan said in Hello New here please help:

I am making an arcade with a IPAC2. How can I set up a two-player system once I'm on retropie? Thanks.

@danmac2 said in No Dialogue or Music in PSX ROMS (pcsx-rearmed):

@dankcushions I have every BIOS you can think of in the bios folder

ok, and the verbose log?

@scoularis please provide a verbose log of the issue, and the override .cfgs involved.

@wsamael I had problems with the SSD in the Nespi 4 but slightly different, I assume though because I use Attract Mode not Emulationstation. Maybe it is the same problem though. Games showed up ok for me, but the romlist is on the SD card so it should. Scrolling through it, so loading media, would be slow then freeze for a decent time before coming back. I followed the guide below and it fixed it for me, maybe it might fix your issue too?

@mitu Listen before you told me that and I cliked on that there was no edit option, now there is and it is doing absolutely nothing. If you want to delete my entire post go for it. I'll find help elsewhere. Thanks

@mitu So sorry for the delay...busy week and didn't have much time to play. Just tried my ps3 controller and yep, you're right it's simply the controller itself.

EmulationStation will use the gamelist.xml ROMs folder, if found, otherwise it looks in /opt/retropie/configs/all/emulationstation/gamelists/<system>. The 2 files are not combined, just one of them is used, in that order.

If you enabled the 'Use Local Art' option in EmulationStation's settings, it will try find a video matching the game by looking under roms/<system>/media/<ROM_NAME>-video.mp4, so even if there's no video declared in gamelist.xml, it might still find a video associated with it.

In fact, what would be the best way to ensure that I get both videos and correct information into my setup?

Don't mix the scrapers if you want video - the internal scraper doesn't support videos so it might overwrite the video tags if you re-scrape with it. Use the external scraper and see which videos have issues - some arcade videos are incompatible with RPI's hardware video codecs and might not play correctly.
