I went into the option to purge the cache after everything was finally set up on my clean install. Nothing happens when I run the command from retropie_setup.sh except to see the line at the bottom:
"Unknown Option unattend"

If you select multiple systems you get that line for each system. Nothing gets deleted. Is this a known issue? I didn't find anything in a quick search.

Board: Raspberry Pi 3b+
Power: 2.5A Canakit power adapter

I now have 101 systems installed on my Pi 4, of which 100 are working at their best. (Well, I could do with optimising the Saturn a bit but that's a nicety.)

The one remaining fly in the ointment is the TRS80. I've always thought it looked a really interesting system but I've never been able to get a flicker out of it - sdltrs crashes straight back to EmulationStation with no clues and lr-mess-trs80-cass does the same but gives me this:

All my ROMs are unzipped .CAS files taken straight from the MAME softlist. I've got the level2.rom, level3.rom, level4.rom and level4p.rom files in home/pi/RetroPie/BIOS (and trs80.zip just for fun). What am I missing?

Issue regarding Experimental Package: lr-scummvm

Summary: After launching any game, lr-scummvm will freeze. Sometimes, no frames render, and only a black screen appears. Sometimes, you can get a few to several frames with audio, but game will freeze within a few seconds. At this point, RetroArch hard locks, and you must force close via console in order to exit. The file runcommand.log does not yield anything of interest, but have linked a pastebin below.

Other notes: Never had trouble with lr-scummvm until I recently updated RetroPie to latest. This also updated RetroArch to version 1.9.4. Nothing else of interest. Have tested all other libretro emulators and lr-scummvm is the only one I've found that yields this problem. Google search was fruitless, unable to find anything related.

No tweaks made to emulators.cfg for this system. No tweaks made to retroarch.cfg for this libretro core. No Core Options generated, as system is unstable and cannot exit/save.

I hope this is helpful information.

I have searched the forum and have not found an answer to this problem.
I am running latest RetroPie on an RPi4.
I have mounted my roms directory from an SMB share on my NAS (this is working for other games).
When I attempt to mount c in Dosbox it fails to mount and indicates the path does not exist. If I ssh into the box I can confirm that the path does exist so I am not sure what I am doing wrong. I have attempted various dosbox cores with the same result.

Running Retropie 4 arcade cabinet. Anyone able to get Neo-Geo Battle Coliseum to run on Atomiswave? When I try to run the rom I only get a gray screen. Or a way to convert to Dreamcast maybe? Kind of surprised this isn't on the actual Neo Geo at all.

Whenever I push forward on the joystick and press the Y button it pops up with save slot notifications on screen. Is there any way I can change the save slot button to the coin button or something?

I have looked all over nets read multiple things but nothing helpful to remap this.
I just finished changing my Mortal Kombat II legacy cabinet using a Raspberry-pi 4 and Retro-Pie.

Hello all, my apologies if I'm asking questions that may have been covered here already, but I just purchased some wireless controllers (link below; think iPremium's the brand & they're not the BEST ones, but Amazon said they're designed to work w/ Raspberry Pi, so they're def. going back if not), and despite the "instructions" on the back of the controllers, I haven't had any luck getting my system to recognize them.
https://www.amazon.com/gp/product/B07FCXL2VV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

My previous controllers were 2 wired USB Logitech F310s, which for the most part have worked great. However I since really only need the full functionality of those to play 2-player, dual-joystick arcade games (i.e., Smash TV & Robotron), I really don't need 4 of them, especially when it'd be nice to have some wireless or bluetooth ones to cut down on cord spaghetti.

Granted, it's been a few months since I first connected & configured those, but when I did, I recall Retropie recognizing them right away. These controllers however have both USB dongles and charging cords, the "instructions" on the back of the controllers just give vague, "Hold these buttons down till this light flashes this color into order to get into pairing mode" instructions that don't really seem to work (w/ no instructions on how one would need to charge a Wifi controller before it works properly).

I'd imagine that there's driver software I need to download, but I couldn't really seem to find it.

Worse-- and I don't know if this is related to trying to connect these new controllers/their dongles and USB cords, now, when I try the typical "reset" function to quit out of a game (typically Hotkey + Y or Hotkey + Start), it WASN'T working... took awhile messing around, but it seemed to have been remapped to like the Back + Right Trigger buttons.

When I try starting a 4-player game with EVERYTHING plugged in (or at least, both wired Logitechs and the wireless Dongles), the Logitechs are recognized but I get 2 notices that "Sony Interactive Entertainment Controller (1356/3290) not configured."

And when I went to Configure Input, the system even recognized that there are indeed "2 Gamepads Detected" (if I have both one of my USB Logitechs and the USB dongle for these wireless controllers plugged in), however no amount of button-pressing causes the system to recognize the wireless one, and after remapping the Logitech to the usual buttons, the "Exit game" function doesn't work at ALL.

So, any advice on how to long to charge, how to configure these controllers?? (if from your knowledge/experience they just suck, that I should return them while my Return Option's still open for some other SNES-equivalent wireless or bluetooth controllers you can recommend, I'm all ears). Any tips to successfully reconfigure my old controllers so that the "exit game" shortcut is working??

Sorry for the long post, just had been hoping to show off the Pi/enjoy some multiplayer TMNT, Simpsons etc action with my nephews this Sunday (give 'em a break from the ol' Minecraft), and now it doesn't look like that's gonna happen.... :/

Hello all, and I apologize if this has been posted before.

Can someone please point me to a resource that explains (in simple terms if possible) how Retroarch config files and menus work? I have a very limited understanding, and I was using the (hotkey)-X menu to try to change some settings while I was troubleshooting some issues playing games.

Unfortunately I made too many changes, but I found an option to go back to my default config file - When I did this, the entire menu system changed. It went from a very simple blocky green and black screen to a very modern looking UI. This is great, but it also changed a bunch of my settings in ways that they weren't set up with a fresh install of Retropie (e.g. having to press twice to exit, save-on-exit turned on, etc.)

TL/DR: I have learned that the config file as provided during a fresh 'retropie' install is NOT the same as the 'default' you get if you reset it. Is there someone I can obtain the 'retropie' original (for SNES?)

Any general guidance as to how these files are located, used, and handled would also be appreciated.

I'm sure these used to just boot and autorun when I was using quasi88 on 4.5.1, but they stopped when I updated to 4.7.1 and now I'm just sat looking at this every time, whether in quasi-88 or lr-quasi88:

Hi everyone,
I'm building a portable briefcase unit with a raspberry pi 4 and laptop screen connected to an lcd controller board. I have Retropie running fine using HDMI0 connected to the controller board. On HDMI1, I've connected a second cable to be used as an HDMI out when plugging to a TV when I want a bigger screen. The trouble I'm running into is that even though I have a separate power button for the controller board, when it's off, I can't get signal sent to HDMI1. The only way this works is if I physically unplug the cable from HDMI0 so that it forces the pi to use HDMI1. It's a bit of a hassle as I have to pop off the joystick and buttons panel in order to access the pi and unplug the cable from HDMI0. Any ideas on how I can make this work? Thanks

I installed RetroPie on the newest Raspbian Buster on Pi Zero, tried reinstalling Raspbian and RetroPie again, same result. Whay might be causing this? I will try reinstalling everything again individually from the manage packages menu but if someone knows the issue please help.

Doesnt happen when installing RetroPie as an OS.

So I decided to get monkey Ball for my Retropie. I have a raspberry Pi 4b 8gb if it helps. I have the Naomi.zip and naomi_boot.bin and for monkey Ball I have the correct zip that doesn't have the dat file inside. I also tried changing the region's but when I boot it it says something like "error 1, game not accepted by board". Any help is appreciated.

Has anyone else had problems with under voltage notifications when using the onoffshim on a raspberry pi 3b and an official power source?

Thanks

Hey all. I know you're busy but just wanted to know if MelonDS either is or will be available within Retropie in the future. I've been using it on my Pi 400 with Batocera v30 and have been very, very impressed with the performance. Now it's not perfect but then neither is Drastic and MelonDS has an advantage of being fully open source at this point in time. I'd love to see it included as I'm overdue a fresh install of Retropie for the 400! Let me know, thanks for your hard work folks.

Re: Splash screen no audio.

Hello, I'm quite new to Retropie and I'm having an issue with the splash screen video not playing audio on boot. I had a look at this post here:

[https://retropie.org.uk/forum/topic/17547/splash-screen-no-audio/16]

Which helped me on the right track. I typed in the following command and the audio worked:

omxplayer -o alsa "/home/pi/RetroPie/splashscreens/filename.mp4"

I just wasn't sure then how to get it to play the audio on boot as I didn't know what was meant in that post by "edit the script and modify line 35". I'm not sure what script I need to edit or how to access it to be able to change the omxplayer to -o alsa instead of -o both.

I also tried typing in this line:

omxplayer -o --adev device Audio out device :hdmi/local/both/alsa[:device]

which gave back:

bad argument for -o: Output device must be "hdmi", "local", "both" or "alsa".

Any help is greatly appreciated!

I can't install run command and the games will not go run. When I try to run a game it is just the desk top screen backs back out and retro pi freezes. It can't found what it needs to install

Hello,
I'm having some problems with the @meleu joystick-selection tool. When I run it I get these error messages:

Traceback (most recent call last): File "/opt/retropie/supplementary/runcommand/joy2key.py", line 241, in <module> chars = get_hex_chars(arg) File "/opt/retropie/supplementary/runcommand/joy2key.py", line 147, in get_hex_chars return out.decode('utf-8') AttributeError: 'NoneType' object has no attribute 'decode'

Then, when I select System specific joystick selection from the Joystick Selection Main Menu nothing happens and it just sends me back to the main menu.

Hi, i've done a search and i cant seem to find anyone that has had this issue.

I recently installed the latest retropie img to my rasp pi zero. i have something called a hubpiwi connected to it, which is a usb hub, with included wifi. it worked great with the older img. but no longer works with the new update. i went back and tried the old img and it works again. there seems to be something in the new img that prevents it from working. earlier searches in google said maybe the wifi driver in the new img needs downgrading? the hubpiwi is realtek wifi.

anyone have any suggestions?
Thanks

Looking to have a NES controller (D-Pad, Select/Start, B/A) have a hotkey of Select, but then a SNES type controller (ABXY, triggers, D-Pad, Select/Start) use a different hotkey button of Right Trigger.

Right now, I have successfully got the Emulator cfg set up to accept the SNES controller of Right Trigger as a hotkey only on NES, but that means the NES controller no longer has a hotkey.

Thoughts?

The goal is to play with the NES controller whenever/whoever wants and have the hotkey be select, but when I play, I want the SNES controller for NES, but I want the hot key of right trigger.

Would love to know some folks' thoughts!

It would be cool if this could be implemented. I have the snes mini borders thought how they would fit well with all the consoles. Would a randomized script be viable or could this be done in the config files of the system?
