@Striderx99 I don't see the point in installing pulseaudio and then disabling it, but RetroPie will use the audio system you have configured in your system - you can install and configure PulseAudio using the Ubuntu package repositories, just like on any other Linux distro.

OK thank you it's still a bit complicated :) why RetroPie has not evolved like Batocera or RetroBat ?

For example:

there are no bezels ? the themes are not complete ? there are no new machines added ?

@mitu great thank you it works :)

@mitu Alright, that sucks to hear but guess i'll get to fixing it the physical way then. Thank you for the responses!

@mitu said in [Retropie 4 on dietpi binary install // need short help]

So, 90% of the time, it works every time ?

Yes, everytime. :D

You'll have to be more specific - are you talking about the front-end (EmulationStation), emulators in general or certain emulated systems ?

I meant both.

@cgutzmer You'll have to install one, so in addition to the game folder, EmulationStation is also configured to look there. Just install one of the ports available (Cannonball for instance, it's pretty small).

I used sudo passwd hiryu and it allowed me to reset the password as that user. I checked the credentials with Firezilla and was able to login and see the folders. As always, thanks for the quick response.

One last Q: I have a acrylic sheet in front of my monitor by way of protection, this has a "bit" of reflection naturally. Would this impact the experience in any way?

Hello, does it work for you or is it inconvenient? in my I have an arcade booth and I have a glass in front of the screen

I have to say it works fine. No problems whatsoever with reflections and so on.

FWIW Here [1] is a list of tested USB Chargers, this guy also runs a section on how he tested (see notes at end of page) and how these chargers are built usually.

Welcome to the RetroPie forum :)

Sounds like an ambitious project.

For the peripherals: You will most likely need to use a analog to digital converter as the Raspberry Pi does not have one built-in. An external MCP3008 can handle up to eight analog inputs (and you can use up to two MCP3008 on an Raspberry Pi). This repo [1] contains an example on how to use an MCP3008, additionally you should enable SPI on the Raspberry Pi [2].

The sources (pedals, aso,) should be able to be run with 3.3V, as this is the allowed logic level for the GPIO. If they have to be do run at higher voltages you will need a level-shifter [3], for example BSS138 MOSFETs are suitable for this. If you apply more than 3.3V to the GPIO logic gates it may damage the Pi.

For the SBC: If you have a Libre Potato already you can start with it for the prototyping with the peripherals (see above). Howerver, the GPIO pinout is not compatible to the Raspberry Pi 3 or 4. Thus it will include remapping when you switch to an Raspberry Pi.

As this is your first project I would refrain from using a different board than a Raspberry Pi, to reduce complexity. Although a Pi has a higher price than a Libre it will save you worries, head-banging and tinkering time in the long run. I do not own a Libre but I read the GPU is proprietary (Mali 450), also Libre Computing does not provide a Debian Buster (RaspiOS 10) image (only Bullseye, RaspiOS 11). [4]
Currently RetroPie uses Buster as OS, Bullseye support is in the works. This means: You will have to adapt the RetroPie-Scripts and esp. GPU related configuration by yourself when you run a Bullseye RaspiOS + RetroPie scripts on the Libre. Plus the usage of a libre computer is at best a niche in this forum, i.e. expect little to no support. If you can afford it head for a Raspberry Pi 4 (2GB is sufficient) as it has enough performance to run racing simulations with theses systems: Sega Saturn, Sega Dreamcast, Playstation 1 and earlier consoles/home computers. However, emulating Nintendo Wii and Playstation 2 games is not possible (Running Nintendo DS games smoothly is a hit-and-miss).

@james-milroy Could be, but the cause is the same - the device is not recognized as a controller, but some other input device. Using evtest instead of jstest would list the input devices present and would let you pick which one to test.

Re-Edited the question.
Aww, i got it.
I first time when i installed Retropie on my Raspberry Pi4 i also installed Kodi on it. Everytime I quite EmulationStation, the terminal window flashes up on the screen and them reboots. It launches Kodi. like it should.

Now since that i had to re-do it all over, reinstall Retropie on to the SD card and then install Kodi once i got it setup on Raspberry Pi4. I finally got Roms setup on retropie after failing for the first time. Everything is looking good now, but here the question. Every time that i quite EmulationStation, the terminal windows comes up, having me to type in reboot, install of going on through and launch Kodi like it should.

Got the problem figured out. It was PEBCAK apparently. Not to be confused with ID10T errors. I had to pull the games out of the .7z archives then all worked well. My wife is so happy she gets to play vectrex!

@DolphinCube said in Retroarch wont save after saving in-game a couple of times:

Certain games I played still has this issue. Especially with my n64 games. I think a fix is that when the system creates a new srm (for gba games). I have to manually delete it after the first save then reset the permissions of the roms folder for retropie using the retropie setup script.

That's weird, there's nothing that changes permissions during gameplay, all emulators/ports are run as the pi user. Did you modify the launching command to run as another user ?

But the configuration file error is still an issue

Why do you need to save the config file ? As a workaround, you can save a game/core override with the settings that you wish to change.

@ecir1299
fastest and easiest way is to burn a download ready-to-go image on the sd

@lfcfooty
@DanTarl solution didnt worket?

@mitu The price of 11.90 € / 10.46 £ seems reasonable. Order is placed and it’s on its way to me now. Thanks for the recommendation!

@Crush This worked for me in 2023
