Pi Zero 2 released

Maybe squeeze a little more performance out of this:

@ashpool oh wait, you're right, I forgot the pi zero I got for the gpi was header less, d'oh! Oh well, spare header isn't a bad thing for another project.

I guess there's a couple of things that wouldn't run on the older arm version of the pi zero. Might be amusing (if incredibly impractical) to see if drastic will run for example

@mitu So use the 2/3 image for the zero 2?

Just got my first zero 2's and looking to put one in my GPI case over the weekend.

Yes.

Surprisingly, I received mine this morning. Well, I can confirm it boots and works with at least one Xbox 360 wireless controller, with the latest weekly snapshot image as @mitu mentions above :)

I'll hopefully have time to do some actual proper testing either later on today or tomorrow.

Spatchcock

@kenjara I'd be really interested to see how that works and whether I should get one (assuming they don't all sell out); I know that RasPi are saying that the form factor is the same, but it'd be interesting to know how the power of the Zero 2W affects battery life.

OK, had a chance to have a quick look over my lunch break - copied a few games over to it, changed a few settings and then for some reason, any time I tried to set up any controller, the controller setup screen froze and I had to F4 out of it.

Tried a few things, deleting the controller configs etc and that didn't work. Then I remembered that I'd changed the GPU memory split from 256MB to 64MB. Once I'd changed that back to 256MB, I could then set up the controllers and get that working OK. I tried a few different settings and now have GPU memory set to 96MB with no issues.

Default PS1 and SNES emulators load games OK; controllers aren't working so I wasn't able to test the games. I suspect I may have messed something up when deleting the controller mapping, but I'll have a look later.

That's all I've had a chance to do today.

@mitu - is there a particular place you'd like any Zero 2W specific issues logging, or should I just wait for the devs to get hold of their own? :)

@retropieuser555 Great news!

The Help & Support forum is where any issues should be reported.

You guys who live in first world countries make the rest of us wishing we could get a Zero 2 within 24 hours too :D

So I've got it working, lr-mupenplus runs super fast right now but that's due to having no audio in the system.

Anyone got any ideas? It's not to do with pulseaudio is it? As I just checked that's not installed

@retropieuser555 You should open a separate topic.

ETA Prime has already overclocked the Pi Zero 2 to 1.3Ghz.

retropieuser555

So here's my little test with the beta recalbox image

dankcushions

@george-spiggott
bit of a useless overclock for retropie, mind - core_freq and v3d_freq are far more beneficial to pi3 (and by extension pi zero 2) as bandwidth and gpu is the limitation, not cpu.

Hey all,

Looking to maybe get one with a GPi Retroflag case, had a few questions for those willing to humor me (thanks in advance!):

About how much time do you get on a reasonable emulator, say NES, via the AAs? Anyone try rechargeables?
The case appears to not have an open port for HDMI out, but it looks like you could drill a hole up the top to do so and run the script to toggle between the displays. Has anyone tried this? Or suggest a different case?
Someone mentioned no HW video decoding on this board, has anyone attempted to run Kodi 8.7 (hopefully Matrix one of these days) on this through HDMI? Can you get 720p?

My dream device would be to have a handheld on a plane. It looks like this would be perfect because you could even power it with a USB bank if you needed to. And then, be able to check into a hotel room, plug this device into the TV's HDMI, and connect home via Plex, controlling it with my phone.

I have a Pi3 with a GameHat but while it can do the latter scenario OK, the handheld part is a bit too clunky for my preferences and it's not really that easy to travel with, although it was a fun experiment. This looks much better and not too underpowered.

Thanks again!

That's not true. It's basically the Pi3B in a smaller package, even the Pi0 has HW video decoding (MPEG4).

ParadoxGBB

@mitu Apologies, didn't mean to spread misinformation! If that's the case Kodi should be ok based on my experiences on my Pi3B.

@retropieuser555 with the following I get some sound, but it's very buzzy, i.e. it's not really routed through the gpi case somehow in /boot/config.txt:

# dtoverlay=pwm-audio-pi-zero^M

dtoverlay=hifiberry-dac

What does the recalbox beta image have in /boot/config.txt ? does audio work on that?

I found that here by the way: https://www.jeffgeerling.com/blog/2021/raspberry-pi-zero-2-powers-null-2-retropie-gaming-handheld
