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

TreyM

Just a suggestion here, OP.

If you have noticed, the GPi screen can exhibit vertical screen tearing at times due to the display actually being rotated in software. The fix is to add the following to config.txt:

extra_transpose_buffer=2

@treym

Thanks. This really does seem to make a difference, particularly for lzdoom.

I would like to report a bug that "permitrootlogin yes" should be put into /etc/ssh/sshd_config instead of /etc/ssh/ssh_config. Current config will prohibit using ssh to other devices from pi device.

@lilarcor

Thanks, that's a remnant from when I first started doing all this: Totally forgot that was still in there.

I ended up rebuilding this system on top of a clean install of the 12/26 Weekly Build and updating all the components to what was current as of a few hours ago and am running tests: It won't have this issue, and in general it seems to be a lot more stable overall than the 11/7 Weekly was. I've also incorporated TreyM's info into config.txt for smoother vsync, fixed a bug with Amstrad CPC support and a couple of minor things.

Not sure if/when I'll release this, as I'm sure people are probably sick of having to reflash their SD cards and I'm struggling to work out a method to upgrade from v1.3 without doing that (The OS components and such would be the biggest thing to handle).

@sliver-x
Thanks for your hard working. I got some ES crash sometime with v1.3 (refreshed image). I tried to update packages in retro-setup and got no audio issue. I will wait for your new build.

Happy New Year!!!

@sliver-x
Could you please share how to make the image in details , like make swap , remove unnecessary files, etc ? I'd like to create one like this for gpi case2

Sliver X

@lilarcor

I listed all the changes I made in the Readme file. You should be able to reconstruct what I did between it and looking at the files involved in some of the changes.

I've released v1.4: This addresses some things that were seriously bothering me up to this point (WiFi problems and EmulationStation's instability at times). This will probably be the last time I update it, unless something major is found that I've missed.

@sliver-x Thanks for all your work i'm using v 1.3 and sometimes i get stuck with error on ES then i'm shutdown and then the system works with no problem, i have no other problem and great job.
Need to reflash to get this v1.4 working ?

Nochii

Thank you for your hard work,
I have a question with DOS emulator. Normally I use joymap-0.4.2. for mouse in my other build it work perfectly but while use v1.3 image the mouse goes to top-left screen and cannot snap to the windows.
I use dosbox for DOS emulator. Do anyone have any suggestion for using mouse with GPicase?

Sliver X

@joao76

Yeah, I was getting that too on occasion. I haven't been able to trigger it on the new ES build that's used in v1.4.

Unfortunately, yes, a reflash is required. But I'm hoping this is it for this project so it should be the last time you'll have to do it.

joao76

@sliver-x i update the ES and if its good i still using the v1.3. The problem is the time time needed to replace the roms.
The ssh connection i get acess dennied , you have this problems with the version 1.3?

Sliver X

@joao76

The WiFi performance in the Zero 2 is so slow (I get 2MB/s if I'm lucky sitting a foot from a decent 802.11ac access point) I don't even bother using it for ROM transfers beyond one-off additions to a set.

Using a USB3 internal card reader on my Linux desktop, I can rsync 130GB of ROMs and all their respective metadata to my Sandisk Extreme cards in about 38 minutes.

You could use a utility like Rufus or YUMI to create a Linux Live USB drive from a downloaded ISO and boot your PC or Mac off it: You'll get full access to the SD card and won't touch anything on your Windows/MacOS install (Though you will still be able to access the OS drive and any other drives/partitiions on your system). If you're not familiar with using Linux, I would recommend using Linux Mint; It's a very simply laid out interface as far as Linux DE's go.

If you don't mind installing drivers into your OS, another option would be to install an Ext4 driver like Paragon Linux File Systems for Windows, but it's not free and I can't vouch for how stable it actually is.

No, I never had SSH problems (Aside from timeouts and disconnnects that disabling the WLAN power saving mode and IPV6 seems to have resolved).

You may want to remove PermitRootLogon=yes from /etc/ssh/ssh_config, as that was a testing remnant I left in 1.3 and below that apparently can cause issues for some people?

Another thing to remember is that SSH uses host keys to determine the identify of the server: If those changed (Either due to another flash, or manually deleting them and having my SSH script recreate them), whatever SSH client you're using may still have cached keys from before and will refuse to connect as they don't match what's currently on the server's side. You would need to purge the cached keys and have it pull down the new ones.

I just did a clean flash of v1.3, connected to WiFi via the Retropie menu/OSK, enabled SSH in Advanced Settings and am now pushing several GB of data to it with no issues.

Thanks a lot for the v1.4 update, it's working very well and I like the looks and responsiveness!

@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.

Sliver X

@retropieuser555

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.

smartazz104

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:
