I may have found a solution, downloaded diskinternals linux file reader, so I can read the files from the card in windows. Then I will copy the roms off and put them on the new install. Fingers crossed

@mitu okay I will comment out the sections for the patches and see if it will build with the added lines in your above post. If I run into issues I will post back. Thank you so much for your help

@shonee That SD card is probably set up in a way that nobody can possibly predict and therefore support cannot be offered according to the guidelines shown in https://retropie.org.uk/forum/topic/3/read-this-first
Only the creator can help you with it.

The best thing to do is install retropie from the official image and follow the first install guide. All your controllers will be autodetected.

@mitu Thanks dude!

@lucent88 said in Rpi 4 w/ official 7in touch screen no hdmi out:

is there a way to make it detect on plug and unplug or do i just need to reboot, every time?

With the config.txt approach, yes, a reboot is needed since the configuration is only applied on boot. Not sure if there is a way to enable it at runtime - maybe for the HDMI port.

@simpleethat said in custom launching images (multiple):

@dan1300 I don't know about being able to display random launching images but you can assign them per system or even per game as outlined here.

I am aware and I have moved forward with that and I will come back to this later when I gain some more knowledge on programming.

Thanks for your time.

@supppp nvm

@spm2600 Same problem.

@mitu ok cool thank you.

Had a look and I can't seem to set my input device to anything other than "Wireless Controller" either within the retroarch input menu. I do have the other devices under /dev/input, and evdev does correctly detect the motion sensor/touchpad.

Nothing else obvious in /etc/udev/rules.d/.

The picture doesn't show the error start (though it may be off-screen), but the init not found message means the kernel doesn't have access to the sdcard's files.
Try to backup your image, then use 7Zip to read the .img file, you may be able to recover some data.

@buzz Appreciate this is an old post but anyone know hiw I access the standaone input settings O inca rebind the keys? I have a keyboard plugged into a Raspberry pi running Retropie to use this emulator. Going to check teh docs file now. Thanks in advance, DtM

Edit - I read the docs and found I can access the menu by pressing my hot key + X. Then went into the quick menu > controls > Port 1 Controls. Here I could change the button by highlighting iot and pushing my joystick right to cycle through the different button options. Hope this helps anyone in future looking for the answer.

@misanthrope whenever i have had issues with those controllers i have uninstalled and reinstalled the xpad drivers. also make sure what mode the switch on the front of your controller is set to

As @YFZdude mentioned, the genesis folder is a symlink (shortcut) to the megadrive folder, so there's no need to remove it - it's not actually taking any space. You can leave it as is, it's ok - the scriptmodules expect a megadrive ROM folder and updating the MD emulators will re-create the folder.

@mitu Swear I did BUT I didn't. Thanks!

@mitu LOL... Don't I feel like an idiot... Figured it was something silly and it is.

@dankcushions

Can you forgive me little rant earlier? Sorry. I've had a good play with it now and I think it's working. And I understand what you mean by pressing the hotkey and F1. Is there a way to have it by pressing F1 alone?

I've Reset Retroarch config and plugged in a Wired Mouse and keyboard and OP Wolf is working now.

I've also changed my RetoArch to Ozone just like my PC. It's much less confusing now. It's going to take some time to get used to this :)

Both advmame and advmess configuration files are under $HOME/.advnance - named advmame.rc/advmess.rc. Game specific configurations are saved there, prefixed with the game/romset name.

@goldengalaxies jzintv working?
