I just powered on my Pi to double check what you asked me to, Audio is set to HDMI in raspi-config and alsamixer shows a volume level of 100, but during boot up I noticed I had sound again.
The only change was a night of sleep, doubt it was that, and me swapping hdmi cables from my pi to my PS4 and back.
My tv is pretty old, so maybe it is messing up the edid?
I did make changes in config.txt that should force it to recognize the hdmi, but that didn't seem to help before.

The RetroPie-setup script updated today and now I can't update lr-snes9x from source with the PGO changes. Anyone else having this issue?

EDIT: Found the problem. So it seems like there's a limit to how many games you can profile, otherwise it will crap out during compiling the optimized core. I probably profiled 15-20 games, so I think it's better off to just go with 5-10.

@allen8

If you're speaking about Kodi specifically, the key commands are actually universal between systems. Outside of that, they still remain very similar and sometimes even unchanged to those found elsewhere.

@pittstone Any chance for a 4:3 version? 😌

Very similar to my build (including the Mayflash), although I cut some grooves in the expansion slot to add some USB ports.

I wired the reset and power button to work as well, using a coupleof trimmed microswitches and GPIO pins, think I used the 'PiGirl' script to add them easily, then set the reset button as an exit emulator option, as I just couldn't configure that with a standard Mega Drive controller.

@mitu i can't

Suggest your power supply. A compatible power supply and one that is GUARANTEED to give the extra power the PI3B+ needs are very different

I could buy an adaptor here in UK for cheaper than you paid that claims to be 2.5A but under load would drop drastically causes no end of grief. Great for low power device like charging mobile phones but hopeless for a high power device that NEEDS a good steady supply like the PI3B+.

People seem to rate the CanaKit 2.5A power supplies, maybe look for them

I personally bought an official 2.5A power supply for the PI3B I have, a lot more expensive than a 'standard' power supply I could have usually bought, but its never given me any complaints after reading power supplies can give lots of strange problems as they work then don't or random errors

My set-up doesn't stress the supply in any way and never had had weird instructions,. I'm overclocked to the limit, running a 1TB USB powered external hard drive for RetroPie, running OSMC for KODI and running a USB powered wireless dongle for the PS3 compatible joypad, plus USB keyboard. All works fine, plus a tiny fan to keep the huge heatsink cool

I have a Freeplay Zero kit waiting anxiously to be put together. In my opinion a fantastic concept! Based on the Game Boy Advance, which has an amazing form factor, ergonomically way better than the DMG-01 if you ask me. You can find loads of GBA shells and you only need to cut away a little bit of plastic on the inside. The Freeplay Zero itself is a really nicely designed PCB to be soldered to a Raspi Zero W, but now they also have developed a kit for the CM3, so a bit more powerful, also a bit more expensive.

Yes, I think providing the beta on the official site (the only source of retropie images for new users) could be a good idea, of course with a statement like
If you're using a Pi 3B+, a Stretch based image is necessary. Here is a compatible beta/RC image of retropie, use it at your own risks, and please report eventual bugs on the forum. Final image coming soon
It would (I think) avoid a lot of disappointment for new users with 3B+, as well as a big load of new similar topics here :)
It could also involve more people in beta testing, and thus help to stabilize the image.
Again, it's just my personal point of view.
I use Stretch image for 2 months now without major issue, and I assure you I've seen a huge lot of far less polished commercial (and furthermore expensive) products hitting GA :)

@dankcushions
Thank you !!

@buzz oh ok sorry didn't know

Hey everybody, I have a quick update for those who want xBRZ-like quality from the Raspberry Pi.

I ended up working around this by replacing RetroPie with Lakka, setting the full-screen resolution there to 1280x720 and using the 4xScaleHQ shader (in the scalehq directory).

Everything runs smooth, tried with numerous games on various platforms, including MDK on PlayStation 1. No lag in the menus either, and the image quality is fairly close to xBRZ (though, of course, you can still tell the difference). I am quite happy with this solution.

Another nice shader you can try is scalefx-hybrid.

@mitu perfect, thank you for the reply. I will check out the link and see what I can figure out. The audio devices don't need pins.

Thank you

@creativename i only use the canakits except in my pistation build which need to run a hub and a hdd off of the same power supply and the canakit isnt enough. I use two canakits on my apple iie pi.

For roms, no internet doesn't mean no network, so if you have a switch or a router (or event with a direct cable) you will be able to copy roms through CIFS, and do SSH.
Moreover, you can simply transfer roms with a USB stick too, see here : https://github.com/retropie/retropie-setup/wiki/Transferring-Roms

Regarding updates, there is indeed no simple way to update retropie without an internet connection.

And don't forget your cell phone Wifi Access Point feature ;)

Slight correction to my above post. After restarting the pi, the stop emulationstation and start emulationstation script no longer works. It is stopping emulationstation but no longer will resume it.
