Hey @algorithm,
nice findings. It seems you got the same device as me. I executed demesg and I add the info from my device.
Mounting the appfs rw was quite easy with "/bin/mount -o remount,rw /dev/mmcblk0p2 /usr/mtdblock3"
and I managed to change some of the default emulators. The emulator dge can simply be replaced with a script with the same name.

I downloaded a "local pack" from http://dingoo.a320.free.fr/local-pack-opendingux.php and all games and some emulators are running. The dge of most games has to be started trough dinguxcommander to work. Its quite fun to play Doom and Duke3D on the device.

Executing "echo 1 > /proc/jz/lcd_a320" will put the video output into the center.

I tried to fire up the old toolchain for opendingux to compile dmenu for the higher res display, but it seems that I'm a little late to the party and the sources can not be compiled without problems on newer systems without problems.
Compiling worked at the end, but without a terminal its hard to say why it crashes/does only display a black screen.

Is it possible to use the "usb network" I read about in the context on opendingux on this device? I could not find any guide to set it up or if its possible.

One other thing I found is that its possible to flash within the device using the update tool

You need the following files

appfs.ext3
configfs.ext3
mbr-uboot-msc.bin
rootfs.ext3
uimage

place them on the root of the microsd

then run dingoocommander and go into the /boot/local/apps/ folder

execute the update tool.

It will then flash the above files and if everything goes well, will mention that 5 files have been successfully flashed and to press reset to continue

Ofcourse the flash resulted in a brick (as I was using a ritmix rzx dump) I guess it could not initialise the components as they differ (e.g lcd etc)

Thankfully the device is unbrickable, so will put the original 4gb sd image back on

Hello,

So i've purchased one similar to the one algorithm posted. So far i love it. I've been able to load games via SD card slot and adding ROMs myself. So far it's great. I didn't know how to make other neo geo games work because i didn't know what .FBA extension was but have since found where to convert my ZIP files to FBA.

So it seems to be able to handle CPS and CPS II games well but has anyone tried CPS3 or any MAME roms that I guess can be played via FB Alpha since I think that's the emulator? Also how about anything above Samurai Showdown 2? I'm planning to convert some ROMS from my raspberry pi to see about playing them here but if anyone has tried please let me know. I'm also going to wipe the card and load only games i want as well as replace some suspect ROMS as well as ROMS from CPS/NeOGeO i do not play to free up memory and add more Master System and game gear ROMS.

I'm not well versed in all the programming stuff but can anyone do a very newb explanation on how to possibly change the emulators to make it work better? or if someone can make a new image of the SD card with better emulators? The GB one seems to cause a crackling noise.

Also can the screen be swapped out? mine has a vertical line running on the left side of it. It's not bad but wondering if the swap is easy and what screen i can use? Thanks for any help!

For $45 they aren't bad to be honest. you'll definitely want to buy a better battery if you plan to do more than game since you can add a SD card with movies on it.

I cut down the 650 games to 356. Removed some Neo Geo games i won't ever play and added the following games which worked really good to my surprise:

1941 ZIP
19XX FBA
Donpachi Zip
DoDonpachi Zip
Guwange FBA
Marvel Super Heroes FBA
Puzzle Loop 2 FBA

Here's what i slimmed my games down to and used my own ROMS as some of the top 100 games for each system wasn't available with the system had. I didn't add any of the hacks/bootlegs the system had either but i may add some of those funny Mario ones.

CPS - 25
Neo Geo - 23
NES - 80
SNES - 79
MegaDrive - 68
Master System - 34
GB - 18
GBA - 10
GBC - 6
GameGear - 13

I've been unsuccessful in getting other Neo Geo games to load. I seem to get a BIOS missing error when converting my zip files to FBA and it won't play neo geo zips. I've also not been able to load MvC, XMen COTA, XMEN vs SF. I've only had success loading Marvel Super Heroes so i'm guessing it may be a romset issue. CPS 3 games are a no go but it might be a ROM issue as well. Attmpeted to boot Red Earth and SFIII 3rd strike from the SD card to no avail.

Another thing to note, MegaDrive/Genesis games need to have a BIN extension so i had to change all the ones i loaded from my collection as they had an .MD extension.

Overall it's a great buy IMO @ $45. I'd definitely try and get from Amazon while it's still available there.

Hmm, mine doesn't seem to want to read the files on the internal SD card anymore. I know they're still on it, I can see them if I hook the unit up to the PC. Also, it turns itself off after a minute.

I think I might just have a duff one here. I got it from AliExpress so it's not worth sending back, it'd take ages. I think I'll try one from Amazon next.

What are the prospects of this being properly hacked, as in booting to a standard Dingux with Dmenu like on the A320 or even possibly OD? I thought this would be getting a bit more attention really seeing as it's a readily available MIPS device which already runs Dingux, even though these boards are pretty quiet these days.

I'm already sorted for emulation really, just wanted something cheap which can be easily replaced so I can leave it in the car. I need SMS emulation though which a lot of cheap devices don't have.

Yeah the SMS support was what originally stood out for me, I mainly need SMS, SMD and Gameboy. On one video review  the sound on Gameboy and GBC was distorted though which is a minus point for me.

Will probably just buy one anyway, they have been as low as ?28 in AliExpress sales.

All the firmware and files are in a microsd card situated inside the device.

The issue that you may face (and many others have) is that sometimes when it crashes (and if it was somewhat writing to the card) it can stop the device from booting or cause some other issues.   However based on your description, it seems the device is working, but the screen is somewhat not working well.

If you wish to take a risk and void possible warranty, you can..

Open the device (be careful, there is a ribbon cable between screen area and motherboard)
Take out the microsd and place in a pc memory card reader/writer
download the firmware from here

https://drive.google.com/file/d/0B0wz_n5he9GpQW96allVTUJNSnM/view

then use a tool such as win32 disk imager to write this firmware back to the microsd card.

Then place the microsd card back into the papk3 plus device and put everything together.

If you still are facing issues, then its more than likely a hardware issue I am afraid.

edit:  at one stage, when I rebooted, no games or icons were visible.  Rather than to open the whole thing up and rewrite the firmware, I fixed it (success varies) by doing the following

Turn papk3plus off.
connect to usb and pc
turn papk3 plus on
wait a while
Try to access the drive (fat32 partition holding the games).  When windows asks if you wish to fix the disk, select yes.
remove usb cable after and reboot

This brought the icons back, but again, depends on how much corrupted the file system is

I have been playing around with mine for a couple days.  It's a pretty capable device, and hackable.  I'm trying to build a custom optimized kernel, and preliminary results have been promising.

It's very clearly using the RZX-50's firmware, well, because.....



The kernel needs to be cleaned up, but we should be able to crack this puppy wide open.

Is that the original PAP KIII or the PAP KIII Plus?
I would like you to tell me how you could change the firmware please

Would make sense if the rzx-50 firmware could work. Rzx-50 is jz4755. Might be close enough to JZ4760 to work.

Some info that might be useful
https://www.barebox.org/doc/latest/boards/mips/ritmix-rzx50.html

If I am not wrong (that could be), isn't that the same processor the a380 had? In that case, would it be possible to use the custom firmware that Alien Grey did as another user is asking in other thread?
