@mitu thanks, yes we've downloaded the newest image and she did order a 3B+.

input_device = "Sony PLAYSTATION(R)3 Controller"
<input_r_x_minus_axis />
</inputConfig>
<inputConfig type="joystick" deviceName="Sony PLAYSTATION(R)3 Controller" deviceGUID="030000004c0500006802000011810000">

Leave SHADERs and use OVERLAYs which simulates scanlines.

1 - install overlays from the retropie menu
2 - go to the folder:
/opt/retropie/emulators/retroarch/overlays/effects/scanlines/
take an overlay file and copy it to your computer, as well as your configuration file
3 - The overlay file is a png that can be cut into photoshop or other simpler programs. cut to fill exactly 640x480 in length.
4 - so remember in the configuration file and png file names etc where you have some resolution (example 1280x1024) you replace with 640x480

note that you are creating your 640x480 overlay from scratch

5 - enable overlays and select the one you created that has 640x480.

this is the method i found to make scanlines correctly match the pixels displayed on the screen

OBS: My english is bad, i am using google translator, i hope nothing written has got double meaning here too. Because in my post about EMULATIONSTATION LOCATION one person even complained.

@uraverageplayer What emulator/game are you starting when it's not working ?
Configuring the joysticks in EmulationStation would automatically create a configuration for RetroArch based emulators (the ones that start with lr-), but certain emulators are not auto-configured (i.e. advmame or mame4all).

THX!
It looks like there was a hidden sign (copy and paste failure)

Thanks for the response. I looked at the controller config and my hotkey button wasn't set to select. Once I did that everything worked as expected.

You can add the combo to the main config file in /opt/retropie/configs/all/retroarch.cfg (this will set it to L+R).

input_menu_toggle_gamepad_combo = "6"

@tb-1599 lr-pcsx-rearmed supports PBP files which essentially smush multi-disc games into a single file.

ETA Prime made a great video that does a great job of explaining how it all works.

I would be more than happy to help you put together your gift. it's really thoughtful of you and cool that your mom would dig something like that.

aguilera.john@gmail.com feel free to drop me an email. I have many resources that can help you.

Its not hard. You just have to hold R2 at the title screen, and the link word will go away. Making it possible to play split screen. Have 2 controllers setup. Hold R2 with player 1 controller at title screen. Link will disappear. I just did it.

@mitu ok sorry

EmulationStation has the X button mapped for choosing a random system or game. If you're in the system list, X will position you to a random system, if you're in a game list (inside a system), it will position you to a random game - you just have to press A to start the game.
Modifying the existing behavior - to start the game automatically - means you're going to have to program it into EmulationStation - something that's non-trivial for someone that's not familiar with programming or EmulationStation's source.

@mitu that's true. thank you very much

@stardan This is an English speaking forum, please try to use it.
If you're a beginner with the all thing Pi & Linux, I'd advice to wait until an official release will be made that will support the Pi4.

Here are my .torrent files for the images of v4.5.1:

@treaves Hello where do you go t swich the spinner defaults controling Y-axis to X-axis. Thanks

Ok your were right not games work fine.
Now I'm having issues with controllers: I setted to port 0 my bluetooth keyboard with touchpad included, but when I go to custom controls on Input Device i see "Not a valid Input Controller for Joystick Emulation"

@KingOfGamer1996 This is only supported on other retro systems like Batocera and Recalbox.
