@jmcdra said in If one were to install mednafen on retropie...:

I'm also noticing this input delay on RetroArch too

You should have started from there instead of making it look like a mednafen issue. In the first place, i can hardly make sense of using mednafen standalone to play nes games on rpi4, there are plenty of better options afaik.

Retroarch has the P+K method to measure input lag, and in my experience the nes cores usually have 0 frames of input lag (i.e. the game reacts at the frame right after pressing a button), there might be exceptions but i doubt it ever goes beyond 1 frame.

If you are experiencing huge input lag on nes emulation, then i can only suppose something unrelated to emulation is at work here, like display lag or something about your controllers.

Please ignore, I did what seemed most simple and plucked the functions I needed from the script and that seems to work.

Hm, seems like the the hid_nintendo driver has some issues with the 8Bitdo pretending to be a Switch Pro Controller. Thanks for the investigatio and write-up.

Generally, users use the XInput mode for 8Bitdo Pro(s) and use the hid_xpadneo driver, probably that's why there haven't been so many reports similar to yours.

@mitu It doesnt work, but I went back to the start, and restored my working backup image (4.8), copied apart ScummVM folder in \opt\emulators, updated everything to 4.8.9, and restored the ScummVM old folder containing ScummVM 2.6 and it works with all the rest updated :)

The problem is with ScummVM 2.9 on Pi 3.

@retropieuser555 I'm baaaack lol

Ok, so updating my retropie didn't help with the save game issues. My son was playing some Kirby games, and they were getting erased every day he logged in.

So, I finally found "resetromdirs" and did it! However, now I have this ...Error after using ResetRomDirs

Although there's a command line, I can't seem to type anything using the controllers. Any help would be appreciated, thank you!

@mitu It's a gaming mouse and it seems that because it has programmable buttons X11 thinks it's a keyboard. None of the mice I've tested worked. Some only have fwd and bckwd buttons but apparently that's all it takes to confuse X11. Xinput test doesn't register anything, but evtest does. I bought a super basic mouse and will try that out tomorrow.

@Rooo7223 said in Retropie games aren't showing...:

there was absolutely no games preloaded.

Yes, that's correct and this is how the image works. There are no games included with the image and you need to add your own games to it in order to play games.

and try to fix it but I really going to do anything. if you do know how to fix this please comment. but i don't feel like going on a emulator website and downloading all the game.

This is explained in the docs -https://retropie.org.uk/docs/First-Installation/ and https://retropie.org.uk/docs/Transferring-Roms/.

@raspberry79
this is as close as we have at this time.

The fixed libsdl2 package in Ubuntu has been released a couple of week ago, after the bug/regression has been reported last year. If you have used the workaround of installing the RetroPie's SDL2 package, you can now un-pin the package and use the distro's package instead.

Changelog at https://changelogs.ubuntu.com/changelogs/pool/main/libs/libsdl2/libsdl2_2.30.0+dfsg-1ubuntu3.1/changelog. Even though the fix was added in Jan 2025, the updated package was added to the updates repositories on 29 Apr 2025.

@Azuli said in Streets of Rage Remake 5.2 on Retropie 4.8.8 Issue:

@ExarKunIv if you mean the "SoRR2" option on retropie extra, it is asking for "libpng12", which I couldn't yet find a way to install on bookworm.

No, they mean lr-bennugd.

@mitu
... DraStic doesn't like HDMI1 audio output, only HDMI0 and MAYBE headphone jack. Noted.

For anyone running into this and having issues for... Not paying attention to details for whatever reason. (ADD in my case)

1: ES_SYSTEMS.CFG was not in the opt folder for me, but it is recommended to have it there anyway for alterations, so make a copy of it there.

sudo cp /etc/emulationstation/es_systems.cfg /opt/retropie/configs/all/emulationstation/es_systems.cfg

2: the <pi> in the code above is the user name/folder. in my case, the folder is called "retropie" - maybe because it's a custom installation. I needed to change things as follows:

<system> <name>pico8</name> <fullname>PICO-8</fullname> <path>/home/retropie/pico-8</path> <extension>.sh .p8 .png .SH .P8 .PNG</extension> <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/home/retropie/pico-8/pico8_dyn -run %ROM%"</command> <platform>pico8</platform> <theme>pico8</theme> </system>

I also was not able to install wiringpi, but the gamepad worked anyway. I wasn't able to exit it via gamepad yet, but I've been very away from retropie, so I might just be missing something. (also I was using a gamepad/mini keyboard combo, so it wasn't an issue yet.)

@mitu
After figuring out I shouldn't be using the 64bit version for this, I got the screen working with sound. Now it's just the usual gambling of installing stuff that's not just roms and emulators in retropie. :v

Thanks!

@mitu Gotcha. Well, I'm glad it was able to resolve itself either way. I'll keep my discussion to this issue on Folly and DTEAM's thread. I appreciate the help and insight, Mitu. Thank you!
