@cornishrooster
I have a similar issue.
I set up the psp folder & installed the psp emulator from binary.

My psp ROM shows up in the RetroPie file manager but I cannot get the psp emulator to show on the menu carousel. I converted the iso file to a cso to save space. Hope that is not the issue.

Does anyone have any suggestions? I have been suspecting ES is the issue but I am not sure.

@bluecoffee said in Two MAME games, one works 2 player one doesn't:

Forgive my ignorance but how would I tell a single rom to use FBNeo?

You can use the runcommand launch menu to choose which emulator runs a rom.

@jdriscol This is an issue with EmulationStation, not streaming via Twitch. You should have opened a separate topic, instead of piggybacking on an existing one just be cause there's a similar error - I'm splitting this into a separate topic.

Your issue is most likely due to PulseAudio being installed - disable PulseAudio from the Audio menu in RetroPie and try again. If that doesn't work, post the output of amixer -l.

@windg Makes sense. I did fix the issue by making the resolution 640x480. It covered the entire screen. HOWEVER, it looked crappy and the aim was way off and it shot far to the side of the cursor in the light gun game.

The volume control error is not related to the crash - it comes from EmulationStation.
Assuming you're using RetroArch and one of the NES cores to stream, the problem is probably in RetroArch's streaming module. You haven't added any of the info asked https://retropie.org.uk/forum/topic/3/read-this-first, so it's difficult start diagnosing what's at fault here.

Thank you. Will look into that.

@bluecoffee said in Pi4 with vertical screen orientation - newest advice?:

Suggests that I should be modifying the file autostart.sh.
Is this correct?

Yes.

Could someone outline the steps that need to be taken in 2022 using a Raspberry Pi 4.
There also seem to be lots of conflicting questions about

Does this only affect Emulation Station, but not the actual games themselves?

Yes.

Does this cause a performance hit like the old method did?

For EmulationStation, not so much.

Do I need to modify each emulator to run vertically as well?

Yes, though for RetroArch you can change the main configuration and it will be applied to each core.

See this topic for a similar question and some recommendations on how to rotate the screen.

I remove lr-mupen64plus-next and lr-ppsspp from retroarch setup.
I install it again and it works ! I can go into the rgui menu (strange thing i mapped hotkey on the xbox button and i can with select + Y !!! (but i can !).
With another emulator (lr-beetle-psx, i can quit a game with select + start.
Not from fresh install emulator. Have i something to parameter in rgui menu

Regards.

@mitu I fixed retropie by adding some roms

@mitu

I've move all the file to my desktop (to have a backup !).
I setting up the controller with emulatiostation and give the xbox button to hotkey
I close emulationstation. The file created named 360 Wireless Receiver (XBOX).cfg
I rename it to Xbox 360 wireless Receiver (Xbox).cfg
Nothing changed and when i launch a game i have always the error : controller not configured.
I've modified the device's name in the .cfg file and restart emulationstation. I've not the controller error and can go into the rgui menu !

Thanks for all @mitu and @windg

Now i know the controller is ok, i have to find why i can go into this menu in another emulator (lr-mupen64plus-next and lr-ppsspp) in this post

@mitu thanks, I had a look around and as I'm building on top of an existing OS was told I should be using this one.

Can you point me in the direction of the dev/stable branch? I figure I can just let it start and leave it to compile. - thanks!

Everything is working fine again, i believe that my internet connection had some issue for a period time.

There's no extra commands in EmulationStation or otherwise that changes the resolution on a stock RetroPie installation. You can change the emulator resolution via from the runcommand launch, but that's about it.

If 240p set via config.txt works, then I don't see why the same method for 480i wouldn't work. How are you setting the 480i resolution for your display - via config.txt or other method ?

Please also add the info asked in https://retropie.org.uk/forum/topic/3/read-this-first to your post (RetroPie version, devices, etc.)

@DuragonArt press start and go to UI settings > transition style. I don't remember if it's "fade" or "slide" (or both) that does the zoom effect; I keep mine on "instant" and it does not zoom.

@mitu Sorry I wasn't clear, that's what I meant by complicated really, not that it was more technically complicated.

Thank you for the reply. Perfect!

No, .zip files are not supported by the core and it wouldn't work. Since 3DO always restarted when switching discs, just keep the each disc separately and restart with the right disc when needed (i.e. when the game asks for a 2nd disc).
