@M4X4M said in Can't select emulator for ROM:

For people still having to deal with that problem:
In my case the tips here didn't work out so I went into:
sudo nano /opt/retropie/configs/all/emulators.cfg
And deleted everything in it manually. After that it worked again (at least for now)

THank you @M4X4M this worked for me, FINALLY. Its been weeks. :)

Worth it not to have to worry about a sensor bar. I'm getting them for my arcade, but would also like to use them for my computer. Moving the sensor bar around could cause problems with the wire.

Does your wireless keyboard have an Esc key ? Try pressing F1 and see if you get the RetroArch menu, from which you can choose to exit.
Btw, your link is cut and it's not working, so there's no way to gauge what kind of keyboard model you're using.

I tried to update script, and after that, new version of the script even told me, that 4.3 is not supported. There in no "install from binary" at all for me. I can install from source, but it gets some old version too (some 1.6.9), and it is not working properly (glitches and freezes).

This means you're running an RetroPie version based on Raspbian Jessie, which is no longer support by Raspbian and - alas - by RetroPie also.

You should try and upgrade by imaging with the latest version of RetroPie (4.5.1) and you can backup and restore your settings and roms using the method mentioned int the Docs.

@grant2258 That did the trick, many thanks :)

@mitu said in Suddenly my save states dosent work.:

Save states are not always portable between emulators, so a save state from lr-gambatte might not worth with lr-mgba . Is the emulator version the same as the one you used for the save states ? Sometimes an upgrade of the emulator makes it incompatible with previous versions' save states.

Hmm maybe it's because of an emulator upgrade. I played the game for a couple of month before I did the backup. And after I think I did an update. Thanks, I did not know it might cause a problem. At least the "normal" save file works.

@cyperghost said in Suddenly my save states dosent work.:

@lesk ... and it's more likely that a battery savestate gamename.srm will work more reliable and may be portable to other emulators ;)

Thanks, yeah the normal game save seems to work just fine ^^

@BuZz That did it, thanks. Now I can unlock the framerate to fullspeed (60). I'll have to double check with mupen, but this might be able to run goldeneye at better speeds. F-Zero and other games are still crashing but that might just be the emulator.

How about if your start an xterm, make it fullscreen, then run

LC_NUMERIC=C emulationstation

UPDATE:

Got it working, this YouTube video helped a lot (for anyone else needing info).

@mitu - I think the default power settings are working, as I just needed to wait a full minute like you said. After that, it goes back down to 1-3%. Good enough for me.

Retropie version is 4.5.13, for reference. But again, looks like all is well. Thanks again guys.

The audio crackling is caused by the audio resample method in the mupen64plus.cfg. This issue was fixed a while ago but looks like it is broken in latest Dev builds of retropie. There is a pull request that should fix this issue it just hasn't been merged yet.

@mitu ah, ok. thanks for the speedy reply. Think I'm gonna splice in some extra buttons to player 1's start and select and place them front and center so users can share the exit buttons...

Appreciate ya help : )

@davidgrohl As far as I know, the current version should be compatible with 1.7.6, it's not a breakning change. However, as @dankcushions said, if your installation is too old and it's based on a previous Raspbian release, your best option is to install a new version. As always, backup your installation before making major changes/upgrades.

sudo chown -R pi:pi /opt/retropie/configs

No, I said removing the file. So just run rm /opt/retropie/configs/psx/emulators.cfg OR provide the contents of that file.

By removing this file, every game I try and boot now says "no config file" and crashes back to the main menu? This is a bummer

I had to reinstall every single emulator, which was a bummer, but fixed the issue with roms not loading with that error. But I still cant change some emulators for certain games, according to other posts it seems like its a permissions error, so I'll diagnose that. BUT for people trying to solve this, dont delete that emulators.cfg unless you want to have to reinstall an emulator.

@reto Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

You provided little information about your system.

@youxia said in Using "super resolutions" with a crt - any way to correct the emulationstation aspect ratio?:

Super resolutions are used for GPIO and HDMI outputs, composite needs different configs.

Ya I know, I got my composite setup perfect, but the only way to get rid of the rainbow moire on dithered textures was to use a shader made specifically for outputting over the pi’s comp plug, doesn’t add much blur, but it’s def not perfect. Was hoping somebody figured out how to hack this res into the yellow plug, haha. Wishful thinking.

@IceChes1 said in MY RASPBERRY PI WONT WORK:

What lights are on?
Certain cases block the HDMI port partially. Remove the case.

If you have just one solid red light, that means everything is fine the Pi just won't boot.

The Pi4 support is currently being worked on, the advmame module is not currently - as-is - compatible with the PI4.
