@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.

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:

cd ~/RetroPie-Setup/ ; sudo ./retropie_packages.sh lr-atari800 well done!

Sound now will work as intended.

@Simberg190 you can open an issue here https://github.com/midwan/amiberry/issues

Use another front-end, maybe ?

@mitu
Thanks, save/load is working.

But strange, usb calbe keyboard is connected, also arrow-keys are working inside the retroPie, but in the Game-Menu no key is working, also no (i.e.) "5" to start the game.
I must use the virtual keyboard (select key). But OK ....

@Drakaen391 Pins #2 and #4 can be used to input power without usb power or run devices with usb power so you have two to choose from. There are even more grounds.

Pins # 1 and #17 are 3V power outputs. I used those instead of the 5V because they would run the fan slightly slower which meant quieter fans as I didn't like the noise.

@quicksilver

I also remember that on original N64 hardware that if the analog stick was pushed while the game was booting up the crosshair/selector would get stuck trying to go one direction.

I also remember this, very annoying. But once my N64 joysticks were worn out, I put the analog stick back a bit to not have to press it as much forward to have it react.

You need to remove then reinstall retropie manager from RetroPie-Setup.

You might also benefit from some RF shielding on both the Pi and the cable. The Pi throws off a huge amount of RFI , to the point where even a cable plugged right into it is going to catch some too. Use a grounded case on the Pi (or just put it in an Altoids tin with standoffs) and a grounded plug too. Don't forget to ground the Pi case to the car's ground too.

Self-Solving Problems Department: the trick is to put "cocoe" in the EMULATORS.CFG line rather than "coco"...

@dmmarti It was simpler than that - I'm a dumdum and I had so many folders with CoCo BIOS files in them from when I was trying to get it work that I'd added the Extended Basic ROMs to every folder except the right one :D

btw @mitu , I had been pulling my hair out for so long with this issue, I'm sure
I owe you a Paypal pint at least...

I want to add one thing to @BuZz' post: Please edit your post and give it a more explanatory topic. Imagine a forum filled with posts named "Newbie … Help!" and the like. Nobody wants to read every topic just to see what they are about.

Just a friendly advice. Welcome to Retropie and to this forum. :)

@robusco said in Multiplayer online and homebrews:

In order to do what interests to me, is the PI 3B also a good model?

Yes, but you might consider the 3B+ model released last year. The Pi4 is also out, but it's not fully supported by RetroPie yet.

Is there a list of which games of which systems can be played online?

It depends on the emulator used. The lr-.. emulators - Libretro Cores - that run through RetroArch can have Netplay ability - see https://retropie.org.uk/docs/Netplay/. You can consult the core page at https://docs.libretro.com and see if it has Netplay enabled (see for instance http://docs.libretro.com/library/mame2003_plus/).

The other thing I was asking about Homebrews is:
Wich version of Streets Of Rage Remake and Open BOR runs fine and have the almost game compatibility? I have to use two version of Open BOR to make the old and newest game both running?

I don't know about SORR and OpenBOR compatibility. In RetroPie, OpenBOR uses an old fork which is optimized for the Pi, could be it's not compatible with games created for recent OpenBOR games - there's whole topic for this with lots of details here.
