@hosscrop OK, this is one of the roms that does run since N64-Emulation was invented.
I guess there will be further advise from users using N64-Emulation on the Pi in short time (i dont, i still own real N64s).

@depawlur said in Ubuntu 20.04 EmulationStation crash after turning off DS4/PS4 controller:

How do I properly install it?
also what package is that?
libSDL or libSDL-dev?
also is it libSDL or libsdl2?

The package in the Ubuntu version you're using does not have the bug fixed. I see that Ubuntu 21.04 (the upcoming version) will have a newer version with the fix I was mentioning before.
You can install it from source, but if it's not something you've done before, I'd say wait for the new Ubuntu version. libsdl2 uses the traditional ./configure; make; make install installation process, common for many open source projects.

You should look into why your controller disconnects - maybe there's an issue with it or the connection to your system.

I followed instructions here, tried to install from ubuntu repo as well as compiled it, but same effect for me.

We don't have instructions for building SDL, if you're referring to the RetroPie install instructions, then I don't think it's any difference how you make the installatio - on a PC the RetroPie packages are always installed from source.

Hello, i'm sad to report tha still in retropie 4.7.11, with kernel 5.10 the shanwan ps3 gamepads still does not pair, though are wworking if plugged via usb cable. Tried both with the shanwan clone driver and custombluez provided in the repos.

So aside downgrade there is no other solution? If so, we are force to wait the fix to be uploaded to raspbian; the script provided by psyke83 is here.

@mitu works, thanks!

@amplifuzz did you try and remap or check the mapping in the Retroarch menu?

Pull up the menu depending on your controller but SNES style controllers is select+X. Then Quick Menu - controls - input section. See if you can remap it there or change the mapping to fit your controller.

Also...remember C64 games also have joystick port settings to switch. But sound like uiu already have that covered.

@mitu Built SDL 2.0.14 with

--disable-video-rpi --enable-video-kmsdrm

The FPS problem still exists with 5.4 kernel, or newer one after full SO upgrade (in this case with fkms or kms), and in this way when emulator is closed EmulationStation is frozen.

Anyway I found a solution, if VERTICAL SYNC is enabled also on emulator (I added a command line parameter for this) also Raspberry Pi v4 version is ok.

If you don't have any other idea I'll stop the investigation, I don't love VSYNC because if a user has a 50 Hz monitor all games with nominal 60 FPS framerate runs at 50 FPS.

Really appreciate your help

@stumcbill
The only two things I can think of are

Drive is full File permissions issue

#1 is easy enough to check, #2 shouldn't be an issue as long as your USB drive is using the FAT32 file system.

When you say you manually save, if you mean through the game's normal save feature, you could try using a save state as an alternative. If a save state worked then it likely would mean that none of the above applies and it is something else.

@ashpool Ok thank you! I was worried there

@lostless OK, so I updated all packages, and now it's fixed.

@mitu оООО!
Oh thank you! on the hundredth attempt, it still worked itself

-magic!?))

@saku00 Sadly, I don't think it is. The only emulator I know of that even supports the DS-i is melonDS, which even then is still a WIP and not available on RetroPie at the moment.

@dankcushions Thanks. I prefer shaders, as the zFast gives you a nice touch of bilinear with scanlines. I found the curved version was slowing things down, but when I went with standard, it was fine. I guess that little extra processing step to warp the edges was just a little too much. When I remove that, things work pretty well (and look great).

@sleve_mcdichael thanks for taking the time to explain this :)

@sleve_mcdichael That seems to have sorted it, thanks very much :)

@mitu Okay sorry for wasting your time, I reinstalled it and it fixed the major issue that the diagonals were really slow. I didn't think it was a game profile issue cause it worked fine on dolphin 5.0. I'm not sure how it fixed it though.
