r/batocera

hi guys, i'm new to batocera and i've encountered some serious issues in batocera v43.

since i'm not a native english speaker so please forgive my poor descripition.

my laptop is an old 2007 released hp 6510b with an 2 core intel processor (Intel® Core™2 Duo T7250 2 GHz Processor cores: 2)

i booted my batocera v43 via an usb sitck (sandisk 32G, usb3.0 compatible )

i fixed the bios files, put roms in the proper folders, and downloaded coverarts from scraper.

at the beginning everything was fine ,all games and emulators work fine to me. but after i run several games (over 50 times i guess) ,the loading time gradually became longer and longer ,the longest time was over 100 seconds.(i timed ) and then ,every emulator, every game stop working, every time i run a game it loads for few seconds and kicks me back to the game list.

i've tried to figure it out by myself in seveal ways , i deleted the batocera.conf and restarted the system, i cleaned my file cache in emulationstation ,i formated my usb stick, and reflashed the whole batocera v43 image again, i put all my to my roms and files to my hard drive partition of my laptop, but this issue happens again and again after i load several games.

i asked chatgpt and it told me to check es_launch_stderr.log and i found MemoryError in last line. and i asked chatgpt again and it told me to check the usage of cache folder ,and i found The base and base2 folders under the overlay mount point show 100% usage.

this issue has been bothered me for weeks and i feel powerless right now.

i will be really thankful if someone knows what happened to my batocera and where went wrong with my computer,and it will be great if there is a solution.

I'm using dosbox on a batocera build and I'm trying to use a joystick for the dos games and I'm having mixed results.

I can get some functions to work but not all and I'm really struggling.

Does someone have a good step by step of how you get joysticks set up?

I'd really appreciate the help.

All games systems dont load. Kick back to game list

I created a fresh install of Batocera and spent tons of time getting all my games added and scraping art work. Then I received an adapter in the mail that in theory allowed me to plug a GPU into a riser that plugged into the M.2 slot. Long story short that didn’t work at all. So I went back and plugged in my Batocera install running off an NVME and after the “booting Batocera.linux” prompt it would just got to a black screen. I took tons of trouble shooting steps including reseating the NVME, clearing CMOS, resetting the BIOs. Nothing worked

So at this point I decided to remove the NVME and put it in a usb enclosure to boot it off my main PC. But now that PC just boots into a black screen. If I unplug the USB cable it boots at normal. So I went into bios so I could get to the boot menu and plug it in. The second I do it completely freezes my entire PC. I unplug it and all the keys I pressed while it was plugged in all suddenly get pressed in quick succession. Any help or advice here?

Every other emulator seems to work fine, and FlyCast will run fine using the bios files I have... Launch the same isos even if F1, open the application..

But the Dreamcast doesn't show up in the batocera UI.

I've done a whole bunch of tinkering (rename folders and reboot, reinstalled the OS from scratch, Confirmed paths in conf files...

The only thing I can think of that's changed is that I updated to the latest stable release.

I'm almost certainly missing something kinda obvious, rather than it being a bug in this specific release.

If somebody could please sanity check me though, I'd be very grateful.

Thanks folks.

I did a scrape for art and videos for psx games and now they are no longer showing up in the game list, even after updating. Here are more details:

- I tried using HFSDB. It hanged on a game and failed with an error saying disk was full but it's not

- Did a refresh of Roms afterwards and the PlayStation system doesn't show at all

- The game files are still there in ”roms/psx/". Games are in sub folders with .bin and .cue files with matching names

- games were in the list before scraping

- as far as I can tell, files were not renamed

What I tried:

- deleted the gamelist.xml file to try regenerating

- restarted my system

- tried moving all but one game to see if maybe it was a problematic game

Any ideas?

Hey everyone, I’ve been trying to troubleshoot this for over a day and I’m kind of out of ideas, so I figured I’d ask here.

I’m running Batocera from an external SSD on an HP Victus laptop. In Batocera system info, it shows:

NVIDIA GeForce RTX 5060 Laptop GPU NVIDIA driver 590.48.01 Graphics API: OpenGL 3.0 / GLSL UEFI boot: yes Secure Boot: enabled

The issue is specifically with Hollow Knight. I’m getting screen tearing, especially when jumping or moving around in the first area. It happens on the laptop screen, and it also happens when I connect the laptop to a TV through HDMI. It is playable, but the tearing is very noticeable and annoying.

The weird part is that the same Hollow Knight build runs perfectly in normal Windows with no tearing. In Windows, it was using the default settings, basically borderless, VSync on, and frame rate cap off, and it looked smooth.

Here’s what I have tried in Batocera so far:

I first ran the Windows version through Batocera’s Windows/Wine method. It launched fine, but screen tearing happened.

Then I installed Steam through Flatpak, added Hollow Knight as a non-Steam game, and ran it through Proton. It still had screen tearing.

Then I found the newest GOG/Linux version of Hollow Knight, version 1.5.12620, extracted it, and got it running through Ports as a native Linux game. That also launches fine, and it may be slightly better, but the screen tearing is still there.

I’ve tried a bunch of in-game settings:

Fullscreen on Fullscreen off / borderless style VSync on VSync off Frame rate cap 60 Frame rate cap off 1920x1080 at 60Hz

I also tried Batocera Windows options like FPS limiter and DXVK when I was testing the Windows/Steam route. None of that really fixed it.

Since the game works perfectly in normal Windows, and since both the Windows version and Linux port tear inside Batocera, I’m starting to think this is something with Batocera’s display sync, NVIDIA handling, or how Batocera is presenting the frames, not the Hollow Knight files themselves.

Has anyone dealt with this specifically on Batocera with an NVIDIA laptop GPU? Is there some Batocera-wide VSync/composition setting I’m missing, or something I can add to the .sh launcher for the Linux port to force proper sync?

Right now it seems like my only reliable option is to boot into Windows whenever I want to play Hollow Knight, but I’d really like to keep it inside Batocera if possible.

Thanks in advance for any ideas.

I know the 43 changelog states canary fork uses f85f4c3, just curious if this is the native Linux version

Hi all,

I updated to the latest version of batocera v43. While everything is working as intended I noticed that ps3 emulator stopped working. I checked it on desktop mode and launched rpcs3.desktop which worked fine from there and launched a game without any issues. The issue is with rpcs3-config.desktop which i think batocera gui or dashboard script depends on. It won't launch. So i opened it as text and i found it points to /usr/bin/batocera-config-rpcs3, which i couldn't find in this path. So the issue is a missing file.

Does anyone have this issue or just me? I figured that if its a missing file in usr directory so its an issue from v43 itself. How can i fix it?

hey guys! I can buy a Lenovo M75q gen 1 with the 3400ge cpu for 200$ cdn. Would it be a great choice for a batocera build up to ps2/gamecube in 2x resolution?

it comes with a single 8gb ram stick and a 256gb sata ssd. I'm pretty sure it would be better to run dual channel (2x8gb) and a nvme instead of the sata ssd right?

i'm asking this because there are some much video out there with a lot of different small pc with ryzen or intel cpu and some seems to struggle with ps2. but those videos are 4-5-6 years old so my guess is that the emulator are getting better with updates?

Lastly it seems that N64 emulation is not that good on those little machine? what about wii and wiiu ?

Thanks!!

Version 43 came out a bit buggy (that's nothing new to anyone). But have you noticed a version 43.1 already available for download? (Butterfly). Has anyone tested it yet?

I've been looking through a million posts and cannot seem to figure out how to get Nintendo DS to run on Batocera. I installed it on my raspberry pi 3 b+.

There was no nds folder at first so I created that and added my roms.

The console still didn't show so I created a custom system and now Nintendo DS is showing and I can see my roms. Every time I try to launch one nothing happens.

I tried downloading the 3 bios files from multiple places and it still doesn't seem to work.

I was going to try to select a different emulator but that console doesn't show in the advanced settings so I think it may be something wrong with the config file.

Any input would be greatly appreciated!

I just set up Batocera. I'm still importing ROMS. I was in the middle of downloading a theme, scraping etc. and then went into controller mapping (wanted to play around with adding Y and X as duplicates of B and A, but BOY was that not worth it). Got stuck, couldn't get to the Cancel button and had to hard reboot.

When I got back into Emulation Station, NES was bizarrely missing. The ROMs I was playing before are still there in the network share, and more have been added since. I tried unhiding empty game systems. I can then see everything else under the sun BUT NES. I tried updating GameLists. I tried deleting the NES GameList and rerunning, hoping it would rebuild it, but nope. It's just gone now. Did I just totally destroy my new build? Do I need to start all over?? Has anyone ever seen this before? I can't find anything about it online. EVERYTHING ELSE works fine, it just stubbornly will not acknowledge the NES exists...

I hit a bunch of snags in the initial setup and really don't want to start over if possible...

downloaded N64 recomp through the content downloader, downloaded banjo recomp using the recommended Linux x64 option, click play and nothing happens, when i try to access folders i get the error unable to start XDG- open with directory /userdata/roms/ports/n64recomplauncher

I know the controller is setup as a keyboard that steam then registers as a controller so when mapping some buttons have actual inputs but others just aren't read at all. Is there any way to work around this or is the new controller just incompatible.

Is it possible to have 2 sindens setup with model 2 games in V43?

🎮 Batocera just rolled out a brand new V3 build with Wayland support for x86 64-bit systems and in this video, I'll show you exactly how to switch over, step by step.
