@mitu said in Libretro and bluetooth problems:

Hm, I recall some reports about Xbox controllers taking long to initialize. Try using the xpadneo driver from - https://github.com/atar-axis/xpadneo, it might work better, but, given the age of your distro, I'm not sure how well it will behave with your kernel version.

These problems mainly occur w/ LibRetro games. When plying Mame (advmame) I sometimes have to manually kill joy2key.py so that a keypress on my controller does not result in Mame trying to load a game when pressing "up".

joy2key - should stop itself, it's only used by runcommand. Are you using it for other purposes ?

Thank you for pointing me to the xpadneo (bluetooth) driver for my Xbox One S controller. It solves some probs not related to RetroArch. In the Libretro SNES emu I still experience a lot of slowdown, but the LR-Atari 2600 emu runs fine.

Lr-picodrive (Megadrive & Sega Master Sytem) appears to work fine. But I have to re-start my controller (on/off). Same thing for Lr-SNES: I can wait for 5 minutes to let the Pi / Libretro "find" my bluetooth controller or I can use the on/off button. "Yoshi's Island" won't run fine no matter what controller I use, ha ha (YI is a very hard game to run because of the extra chip it had in the cartridge).

[off topic] Still have that nasty problem that joy2key.py won't get killed after starting a game. This results in, for instance, the F10 keyboard key getting pressed by my controller in Mame4all. The F10 key makes Mame throttle to "ridiculous speed", just like the spaceships in "Spaceballs The Movie".

sorry i havent readed the read-this-first. page im new here hope you doint mind.
if you want to know this is the exact message

lvl0: Error creating SDL window!
Could not get EGL display
lvl0: Renderer failed to initialize!
lvl0: Window failed to initialize!

@xtratos24 I just noticed that there's also a section about the Wiimote in the Docs:

https://retropie.org.uk/docs/Wiimote-Controller/

@rkoster Cheers, but as I said, unfortunately I'm unable to install lr-mess for reasons I don't understand.

@theRog05 If you're re-starting again, then get the 4.5.1 image from https://retropie.org.uk/download, which should have the necessary pre-requisites installed.

@mitu @grant2258 thank you both for all your help. After I couldn’t get any of my controllers working, I imaged a new SD card and started fresh. I can successfully use the Dragonrise controllers. I’m thinking the problem may be permissions related as for some reason the default account (pi?) May have lost permissions to write config files. I’ll look into it.

Thanks again,

Turning down the gamma to "0.5" has made a remarkable difference. What a strange default option in RetroArch! Thanks to everyone who threw in their $.02

Nobody? Not asking for any solutions, just want to know if it runs properly for anyone else...

Ah, fair enough, I’ll just keep trying to troubleshoot tonight.

Also, it seems I was mistaken about my initial problem getting fixed- for some reason the touchpad keyboard will work a good percentage of the time (more often than not) both in and out of the terminal, though for some reason it’ll stop working every so often when I switch to terminal. Still wondering if it might not have to do with the latest build for my screen driver (because at least now it works more often than not), though I’m not sure why this might be a factor. Sorry, I just don’t know enough about Pi’s/RetroPie/Linux to know how/where to start troubleshooting. Thanks!

Anyone?

Do I have to map the controller for every emulation system like nes Nintendo PlayStation etc?

@mitu

@mitu said in One systems sample videos aren't playing:

@bfollowell What video player option are you using in Emulationstation ? omxplayer, the HW accelerated option, has issues with some videos. If you switch off the hw accelerated video, do the videos play ok ?

I really didn't setup a player. I just put the media files in the individual ROMs folders, along with my gamelist.xml file, and the videos showed up and started playing. So, whatever player RetroPie uses by default, and however it is setup.

Actually, before I submitted this, I decided to go and check. I found OMX Player (HW Accelerated) listed under the Main Menu under Other Settings. This was off. I turned it on, and the videos for TG16 start much faster now. There is still a slight delay, but only about a second. I still have no idea why it's only this one system that exhibits this behavior, but I'm happy with it now.

There was a thread about this in 2018, but I don't know if the two methods described there by @herb_fargus are still working.

https://retropie.org.uk/forum/topic/17459/retropie-screen-mirroring-streaming-casting

For my part, I gave up on this and use an hdmi splitter and vga converter instead now to put the picture of my arcade cabinet on my video projector when I throw a party at my place.

I know this topic is pretty old but I just had this happen to me. It happened because of a conflict in RetroPie auto start. I had manually entered a command line to auto start and then later chose the auto start option in RetroPie setup. Seems the two didn’t work well together. I resolved it by getting back to RetroPie setup in command line and deleted the auto start line. I’m definitely a noob so I apologize if my terminology is wrong. But I’m learning. Hope this helps someone else.

@Ashpool
Guess thats it
its 2.5 connect usb only

@mitu settled, many thanks.

Hi,

I've managed to fix that by patching lr-atari800 src before build.
Login to retropie host via ssh then do the following:

Sound now will work as intended.
