I use this config file now and it works:

# For more options and information see # http://rpf.io/configtxt # Some settings may impact device functionality. See link above for details # uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan #disable_overscan=1 # uncomment the following to adjust overscan.

@Spyhunter

Just use hypseus.

@Souciot said in Audio devices not found GPi case:

@G30FF in the readme of the patch it's written : "Why need to install display GPi Case patch for Retropie and Recalbox?" so I suppose it shouldn't mess with retropie ?

I only have experience with the GPi Case 2, so my mistake. The GPi Case 2 patch includes one for Recalbox 7, one for Recalbox 8, one for Batocera, and one for RetroPie. I downloaded the GPi Case 1 patch, and I see why the recalbox string is there, because it's included in the patched config.txt. Sorry, I won't be much help here.

@mitu thanks you, I hope it will help.

P.S. seems like it helped, enabling v-sync doesn't causes sound issues anymore.

Whats strange is if I play Castlevania on my desktop in Mesen at 1x scale this same phenomena occurs (its not an aspect ratio or integer scaling issue either, those settings dont alter this in anyway) At 2x you can still see it happen but not as apparent. 3x and up it doesnt happen. But if I record gameplay at 4x then open the video in VLC and set zoom to 1/4 bringing the image back down to 1x, there it is again!

What the heck is going on here? Is this some sort of lcd pixel refresh rate thing? It happens in games like Castlevania, 8 Eyes, and Ninja Gaiden, but not Super Mario Brothers. It also happens in other system games like Rastan for Sega Master System. And changing the emulator/core doesnt affect the outcome.

I would love to know exactly what causes this.

So I was having the same issue with my gpi case 2, what I did was I used the update feature and after a update and reboot it works perfectly.

There are 5 main methods to configure WiFi.

@omission229
I don't see why not. I do everything on Manjaro Linux with no issues. I'd have thought a Chromebook would be much the same. Never used one though.

oohhhhhhhh. Thank you so much for all your help. Also will this work on a raspberry pi 4?

@usrstu Please can you post a verbose log. How did you update btw? Make sure you update RetroPie-Setup if you installed from source.

@mitu ok sorry, I thought it was a fairly simple operation to do (copy and paste) unfortunately I will never be able to get in touch with the builder authors. thanks anyway and sorry

Hey guys

I followed your advice and I'm pleased to report that GBA games are now working under the other emulator and they are working really well. No more stutter! Thank you! Finally my GPI can run more than GB games! :D

Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first. Include what games (and systems) you tried and are not working.

Should I run the remaining "Remove the Old folder if it exists" and "Use Alternate background for main menu" items?

I don't know, you'll have to ask the theme author what those mean.

I tested the theme and it works fine at 640x480 (video & all), unfortunately I don't have a way to output 320x240 to test it at this low resolution.

@DieKatz I just wanted to say thanks for noticing this problem. While playing Sonic 3 on my gpi I noticed that some of the sound effects weren't playing at all. I could never figure out what the problem was. It was the same stereo/mono issue as you were having. So thanks again!

@mitu Just a quick update. I compared the .bin/.cue files on my pi to the database. It turned out, that half of the .bin file was corrupted so I just had to put them again on my Pi0. And now MGS runs pretty well. Thanks for the help! :)

@tmshll said in GPi SSH/PuTTY issues:

@cyperghost Hi,

I created an SSH file (blank txt file and then deleted the extension) I also made sure SSH was enabled via interfacing options through Retropie.

As for setting up the WiFi I created a wpa_supplicant.conf file on my SD, and input my details (am I right in thinking my SSID is the same as my WiFi network name on my router?) I think this worked as I tested the WiFi by downloading extra splash screens via the GPi case.

Yes ... that seems correct.

192.168.1.7

Yes, that's your IP ....

@mitu
Windows is very weak in handling ports ;)
You can use pping and a command like PPing retropie 22 to determine if port 22 is open.

@tmshll In your example the call would be PPing 192.168.1.7 22 to check connection to SSH port 22

( First of all: sorry for the necro-reply. )

I noticed I'm not able to exit advmame either when using
Start+Select on my GPi case.

This is how exiting is defined in the advmame.rc config file:
input_map[ui_cancel] joystick_button[0,8] joystick_button[0,9] or keyboard[0,esc] It is configured likewise in the advmame-1.4.rc config file and it does exit using that version. Tip: setting MISC_SAFEQUIT = no should allow for exiting without a confirmation popup.

I'm wondering though: since I'd like to use advmame instead of advmame-1.4 for some particular roms, does anyone have a solution to the exit not working on advmame (when using GPi case)?

Addition #1: advmame-1.4.rc (Exit Working)

Addition #2: advmame.rc (Exit Not Working)
