GPi Zero 2 v1.52 & GPi Zero v1.15(Retropie Images for Pi Zero/Zero2 + GPi Case 1 & GPi Case 2W)

kunceton

@sliver-x hello, thank you so much for this package. But after flashing this build, I met a problem about instant saving. The hot-keys for instant saving, L+select for save and R+select for read, are not working when I press them. Can you please help to confirm how can I make the instant saving setting? Thank you!

Sliver X

@kunceton

Reconfigure the controls via EmulationStation's config menu and make sure Select is bound to Hotkey.

Hey this is awesome having an easy to run image for the retroflag and pi0 w 2, no ppsspp or drastic though? I know they're both far from perfect, but can be setup with xboxdrv and for certain games in the library run pretty well. Probably as good as you got out of the pi3 anyway?

kunceton

@sliver-x thank you bro, I will try it.

I only set up N64, even, due to a lot of requests: The performance on it is not very good and can only really be played with a bluetooth controller with more buttons anyway.

You can add emulators as usual in Retropie on my image if you really want to run PSP or DS.

Is there something in this image that is disabled that prevents connecting via SSH using the hostname? Connecting using IP works fine, but using the hostname it never connects.

@sliver-x Thanks for this marvelous image!!

I found something about the malfunction of the d-pad. If you try to do a restart from the emustation menu, the emulatiostation config file of the pad change, change the dpad for an axis input. That's my case, I have to change the configuration manually to work again.

I checked that this only happends when do a restart from the emulestation menu, If you do a poweroff/poweron via power button works correctly.

It also happend with the retropie config file:

The hostname is "gpizero2" by default.

@abocaman

I ran into this a few times myself, but doing Safe Shutdown with the power switch then turning it back on would always fix it. I tried to find a way to remove the shutdown and restart options from the menu, but short of recompiling ES I didn't see a way to do that.

I like ES, but it gave me more problems than anything doing all this.

joao76

@sliver-x But under ssh login user are: pi and pass: rasperry this the same as the default .
There are no changes here right? i can't connect using ssh always get acess denied.

Sliver X

@joao76

The credentials are the same, yes. You have to enable SSH out of the box. I made a script under "Advanced Settings" that will handle enabling and disabling it from EmulationStation.

edit Also note that the image has no SSH keys on a clean flash: When you enable it via my script, it generates new ones. If you have cached keys from a previous flash your client will think it's being spoofed and refuse to connect until they are cleared on the client.

smartazz104

@sliver-x Unfortunately that didn't work; I have also already updated the hostname via raspi-config (where it was pi by default). Would updating here break something?

Sliver X

This post is deleted!

Sliver X

@smartazz104

No, it won't break anything. I just changed the hostname, and I can connect to it. Reflashed a clean install, default hostname is reachable after connecting it to WiFi and enabling SSH. Changed the hostname after this, can connect to the new hostname.

Not sure what's going on for you, but it sounds like it's something to do with hostname resolution in whatever is handling DNS in your LAN. Or the machine you're trying to reach it from. Try flushing the DNS cache?

smartazz104

@sliver-x I ended up adding an entry to /etc/hosts on my Mac for it to work. Thanks for your help.

Sliver X

@smartazz104

If you're using a Mac, they use mDNS to do hostname resolution: You need to enable Avahi from "Advanced Settings". Once you do that you shouldn't need a static HOSTS entry.

smartazz104

@sliver-x Great, thank you once again.

@sliver-x

Just had an idea. With some experimentation, the overclocking script could become an undervolting tool as well. I am currently experimenting with stock 1000MHz freq and an over_voltage value of -1 (negative values are indeed possible for those who didn't know)

If it's stable, I'll keep going down to see if -2 works on my board. The thing is, (and I'm not sure if this is the case or not) if the voltage value is the same as the Pi 3, but the CPU is running underclocked vs the Pi 3, there should be a fairly decent amount of undervolting headroom.

Sliver X

@treym

The overclocking script I wrote sets the voltage level, even if not present initially in config.txt (At stock voltage): It should be easy to modify for this purpose.

TreyM

@sliver-x yeah, I'm going to modify it myself. Just thought I would throw the idea out there in case you wanted to drop a patch on the OP if you thought the idea was useful.
