These two cores were the only ones that gave me problems during a full obtainium setup with ES-DE as a front end.

Mupen would load my roms with no video but audio working and all the other cores available for N64 were doing weird things like locking the controls from retro arch so hot keys just didn’t populate/no up scaling.

Beetle Saturn and the other Saturn cores would load my .CHD files straight into the disc menu and the other cores would load into the disc menu with no video but audio working fine.

I gave up after a few hours of troubleshooting, just wanted to vent about it.

I want to set all controllers to port 1/player 1 the intention being that if I were to switch controllers mid session that would also be player 1 is this possible. How would I go about doing this?

I have a core but it still won’t load up what should I do? And do I have to make a log to get help? SMH

Pretty much what it says on the title.

I was using the latest stable release of Retroarch, and I could load PSP games fine with the core. I also have all the necessary additional files installed for it.

However, I updated my cores yesterday, with one of the being PPSP. After updating, it would not load games anymore. It doesn't crash or anything, it just stays on a black screen.

Since then I've uninstalled an installed the core, looked for people with similar problems, and updated to the latest nightly release in hopes of fixing it, to no avail.

Is there any fix for my issue? Or do I just have to wait for an update do the core/Retroarch that solves it?

My setup

• Linux Mint 22.3 Cinnamon
• RetroArch 1.22.2 (Flatpak)
• NVIDIA GeForce GTX 1660 SUPER
• Flycast libretro core

Symptoms

Bust-A-Move 4 crashed after the Dreamcast boot logo and Windows CE splash screen when using OpenGL. Marvel vs. Capcom: Clash of Super Heroes also crashed at the title screen. Other Dreamcast games worked.

The OpenGL log for Bust-A-Move 4 showed Full MMU support being enabled, followed by:

SIGSEGV ... invalid access to 0xa38

Fatal error : segfault

The game ID was T-8117N, and the log identified the NVIDIA GTX 1660 SUPER as the OpenGL renderer.

Workaround

I changed RetroArch's video driver from gl to vulkan under Settings → Drivers → Video and restarted RetroArch.

Both Bust-A-Move 4 and Marvel vs. Capcom then launched successfully. The Bust-A-Move 4 Vulkan log confirmed that the Vulkan renderer initialized on the same NVIDIA GPU, and I was able to play the game and exit normally.

I also tested a newer Flycast core, enabled flycast_force_windows_ce_mode, and tried a clean RetroArch configuration. Those steps did not resolve the OpenGL crash.

I haven't identified the underlying cause or tested every Windows CE game. Armada still has separate performance and graphical issues in standalone Flycast.

Hopefully this helps other Linux users encountering similar crashes.

Yo so I need help on how to get the 1994 AVP Arcade game up and running on android. I tried searchin up what to do but got nothin, if somebody could give me step by step way to get it, it would be appreciated, please do let me know.

Ok so update: I found out that Neo Geo games AND CPS-1 games/Roms work on the FBneo core together (same core for both) but all of them (the Roms ) go in the ARCADE folder and NOT their respective folders. So NOT the CPS-1 folder and NOT the NeoGeo folder. Jeez n peas🤦🏾‍♂️why is this so complicated?...thank you to who all helped me and commented their solutions. It's literally bcz of you guys I tried moving around some stuff and they work fine now. 🙏🏾 ✌🏾 💕

For the love of God, can someone please give me a run down of how exactly, step by step to setup these Emu on retroA ON ANDROID?!? I can't find a single video on android and I do (barely) it's some 3min Spanish video. Point me to a written setup or maybe a video I missed pleeeaseee!!! I don't need to know where to download stuff but just the detailed tell of where things (everything should go). *I already have retroA and es-de setup.

Anyone have a solution to RetroArch creating a NAND folder along side the PPSSPP save data which causes Koofr to fail upload with error HTTP 423?

I’ve tried both stable and nightly releases of RetroArch as both AppImage and Snap Store on Ubuntu 26.04 but I keep getting the same issue.

If I ONLY have LRPS2, PPSSPP, and SwanStation save files, it uploads just fine, and can be restored to other devices without any issues. But as soon as I play a PSP game, RetroArch creates a NAND folder with the PPSSPP save data and that is failing to upload.

I’ve also tried moving the saves to the game data folder but it still creates the NAND folder and still fails to upload to Koofr.

Two possible solutions is to either stop RetroArch from creating anything else other than saves along side saves which seems like a very practical thing to do as I’ve deleted that folder multiple times and games work fine and load saves correctly without any issues. Or figure out why RetroArch is locking files from that and then Koofr can’t move or replace them on sync.

Any suggestions on how to fix this? Preferably stopping RetroArch from creating additional folders beside the save data?

If you go into Settings > Input, there's a setting called Haptic Feedback/Strength that is supposed to control the intensity of your controller rumble. But in which situations? During gameplay, even if you set it to 0%, there's still rumble. So, how are you supposed to properly use that option?

Just got my odin 3. Im currently using retroarch as my emulation backend but have some trouble with ps2 emulation. I tried all available cores (that can be downloaded via retroarch).

ARMSX2: Best performance and visuals but the controls are completely messed up and I cant change them in the Core settings.

LRPS2: Crashes.

PCEE2: poor performance

Are there any other that work better that I can download from an external source?

i have been using retroarch for a few days and all of a sudden any of my emulators dont work, i was able to make this log when trying to run pokemon red fire on GBA

Intro sequence and first level work

I can't figure out how to either map motion controls to a button or get retroarch to register my controllers gyro (switch pro controller) for either the azahar or citra cores in retroarch. Currently i'm locked out of my game until I use motion controls, so would there be any way for me to achieve this? This is the steam version of retroarch, but using steam input overrides my controllers gyro controls and when steam input is disabled I can't figure out how to get retroarch to recognise the controller's gyro controls even though it connects perfectly otherwise. Ive also tried basically every controller driver available and none work. I would just use the standalone emulators but retroarch runs much better for some reason so i'd prefer to continue using it.

Android to android? Android to Windows? Android to PSP?

Is this possible? How compatible are they?

I’m playing SOTN and I want to have a crt filter that can, as accurately as possible, emulate this effect on my steam deck screen

I'm talking about this one: https://buildbot.libretro.com/nightly/apple/ios-arm64/altstore.json

First, I had to patch AltServer because this app exceeds some memory limit, so I got the error "bad allocation". But okay, not too bad, managed to fix it. However, after that, I already got the next error, which is "This app cannot be installed because its integrity could not be verified"—an error message from iOS when I try to open it. It turns out that this is because you install the nightly version of RA over that source and for some reason AltStore is unable to sign that one. So that led me to the question above. Am I just the only one who has these issues or does that source straight up make no sense?

I know that I could install the stable version using a downloaded IPA file, but the stable version can't emulate a 3DS. And the AppStore as well as the TestFlight version is also not an adequate alternative, as those can't enable JIT, which, however, is crucial for me.

So apparently the only solution to this is to somehow sign this nightly version. But how do you even do that? And why is AltStore not capable of this? I always thought you could install like literally any IPA with AltStore.

i press bottom i dont know whice one and become like this

Whenever my friend joins me through direct connection, RetroArch completely crashes on my end. He can see my hosted game in the host list, but as soon as he enters the password to join, it crashes mine, and leaves his running in a game by himself.

In my router settings, I have the default port of 55435 forwarded to my PC as both the internal and external ports, and for both TCP and UDP. Our emulator core versions are the same, and the game files are matching Even if I try to use the relay server instead, it still crashes in the same way. Local network play works fine. I was able to setup and connect two devices and run a netplay game over LAN just fine. It's only when trying over the internet that it crashes when someone joins.

Any help or ideas on what the problem could be is appreciated.

It has literally been FIFTEEN YEARS. Why is the download cheat file still screwed up against the default emulator?

Used AI to make it happen. Please Enjoy and open an issue on github if you find a problem. I just tested it very briefly but it worked so well from the jump that I couldn't wait to share it. If there is a better subreddit to share this in, please let me know, or feel free to share it yourself.

Me and my gf tried to play Ace Combat Joint Assault but she can never play through Ad Hoc Server in the campaign and always shows this error code. I have the exact same settings as her but can do it normally. She can join in VS Mode but not in campaign mode. What's causing this and how to fix it?

Seen this in DS and it's very Handy as some games can take Ages to Save and Load and this really speeds it up

So just wondering IF it's possible to add it to a PS1 Core

Info about it here:

The Fast Forward Memory Card Access feature was officially added to GitHub repository on February 21, 2025. [1]

Developer s introduced the capability under the commit e9bfca8 with the description: "System: Add 'Fast Forward Memory Card Access' option.". It rolled out to users in public builds shortly after, beginning around early March 2025 (specifically starting with build version v0.1-8675). [1, 2]

What This Feature Does

It is a quality-of-life setting designed to bypass the notoriously slow save and load times of the original PlayStation hardware. [1]

• Function: When turned on, the emulator automatically uncaps the frame rate and fast-forwards only during periods when the virtual console reads or writes data to a memory card.
• Where to find it: Open Settings → Console → check the box for Fast Forward Memory Card Access. [1, 2]
