@MortenHB the 3B model supports only 2.4Ghz Wifi networks, make sure you don't share a 5Ghz SSID on the router. Also, if the Wifi networks aren't separated/isolated through a firewall. Your problem seems purely related to the routersettings/restrictions.

Thanks for this quick reply.

@Darksavior I know this is an old old post, but I just wanted to say THANK YOU for the tip about mode 2! Completely different experience this way - it is properly usable! 👍

@Electron there is a rotation screen parameter you can add to /boot/config.txt, but it adds some extra processing to the GPU and had a performance impact. Try it out and see how it works.

@bpreston26 look up the Arcade quick start in the docs to understand how Arcade emulation works. As @GoldManSex778 said, you're just using the wrong Romset for the emulator.

@mitu said in Hash sum mismatch error:

don't have SSH enabled, then

I just enabled SSH, and updated the thread info with read-me-first topic.

I have installed the 4.4 image from the RetroPie site, and I have internet connection, I made a ping to www.google.com and work.

I now with PuTTy connected to the RetroPie.

What should do I do? Where is the path to get the log files?

Looking into it, the web

http://espejito.fder.edu.uy/raspbian/raspbian/pool/main/u/unzip/unzip_6.0-21+deb9u1_armhf.deb

isn't working, I copied that URL in my Google Chrome browser and a error file was downloaded.

But

https://espejito.fder.edu.uy/raspbian/raspbian/pool/main/u/unzip/unzip_6.0-21+deb9u1_armhf.deb

Work's just fine, so look's like

sudo apt-get upgrade

command isn't working because that http isn't https.

EDIT:

I have changed the /etc/apt/source.list

and added

deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi firmware deb http://archive.raspberrypi.org/debian/ stretch main ui

it seems it working now, the upgrade is doing downloading files without error.

But, is ok to use those repositories?

My guess? Is a problem for South American people (I'm from Argentina), that the source list is unupdated or wrong setted, because when I got the url it use http and not https, looks like that's the main reason.

I tried to install the retropie-manager (after the update & upgrade) and I got this error

Could not install packages(s): python-dev virtualenv.

EDIT 2:

I have it working, to workaround I just change /etc/apt/source.list.p/retropie.list (or something like that)

and added (can't edit because the Akinet detect that is a spam, but add deb before the url)

https://espejito.fder.edu.uy/raspbian/raspbian stretch main

After saving the file, I use sudo apt-get clean and sudo apt-get update and everything is working just fine (or it seem's like that).

The error is that the URL is unupdated, but isn't the best option.

Idk if I have to send an email to the RetroPie developers to update the repo url for Argentina.

@anmag70 Is your hotkey button also select?

Fixed it, I simply updated lr-mame2003 in retropie setup.

Many thanks for your help.

If you mean "how do I make the Pi auto-login to Retropie" then:

sudo raspi-config
Choose option 3: Boot Options
Choose option B1: Desktop / CLI
Choose option B2: Console Autologin
Select Finish, and reboot the pi.

@wkelley89 There is a dedicated reddit sub for the GPI case. Other people have had the same issue : https://www.reddit.com/r/retroflag_gpi/

or you post this on the github page of the port maybe they can help you more or you try to install an older version as i said before eg: 0.2.1 or 0.2.0

Turns out I am wrong. Issue still persists.

I tried using a separate micro SD card with the same v4.4 retropie build and got the same results.

I tried disabling WiFi and bluetooth. This dropped the temps from 75+ C down to an acceptable 50-60C.

Regardless the unhandled exception, freezing, and segmentation faults still continued.

I surmise the pi zero w I bought new is defective.

@Chameleon said in Retropie Freezing / Errors:

I know this is an old thread but I want to keep related information in the same location.

I encountered the above unhandled alignment bus error.

I then found this post:

"Bus error on Raspberry Pi 2 armv7 command line app #22384"

https://github.com/dart-lang/sdk/issues/22384

I then went to rasp-config via emulation station UI and changed the localisation setting to my locale.

Example: AMERICA > pick a city

So far I do not see this alignment exception pop up. It would pop up fairly fast prior simple idling on the emulation station menu.

Hope that helps.

@Tackskull
The gamelist.xml needs to have the assignments for each and every piece of media. If its a new .xml it won't have any direction to the scraped graphics.

I'm sure there must be a way for it to work, in emulationstation there is an option for local media, I don't know what that means but I always thought it was something like that. In skyscraper there are options for local media, but I don't know if it would work like that without the cached database for everything.

@quicksilver
It’s literally a 15 minute fix and the standalone for retropie works just as good as the lr version providing you bind your center gamepad button to be able to access the emulator menu.

@tinsel read the sticky topics as agreed on signup and open a new topic with details of setup.

thank you for all of the info i will try that out
