Great work, I'll download the image and take a look.
Very interesting the menu you found, let us know if you figure out how to access it again
No problem, hope it is of some help, there has to be something different between the pandora 6 and heroes 5 apart from just the menu art, and amount of games loaded. The reason i say that is the image i created of my pandora6 can be read on a computer system with ext4 partition support, or at least one of the larger partitions can.
When i Burn your heroes5 image though akira84 it boots up find and works just fine on my box (obviously did not try all 2020 games though) but plugging the sdcard in via my computer direct NOTHING can be read from it, so i assume either the file system is different (which would be strange, i doubt they have gone to any effort beyond loading different amounts of roms and changing menu art) something got corrupt during my download (which is a worry) or something weird happened when you created/copied the sdcard to make the image. Can you or nasoftz confirm i am not going insane and confirm that my image can be read IN PART on a computer with ext4 support but the heroes5 image can not.
nasoftz ha scritto:maybe the same menu that launch factory settings apk? I managed to enable it pressing “insert coin”+”1player” buttons togheter while the system is booting up

Ah right it may weel be

, ill check when i get home from work tonight and report back, if it is that and it that works on my box.
nasoftz ha scritto:all in chinese .. however you can read the menu content using google translator app on your smartphone, just take a photo than use it to translate the content from chinese to english

Yep that was my plan, then either make notes what each option does save screengrabs if possible and also see if there is anything in there which could unlock this box a bit more.
nasoftz ha scritto:I suppose that pandora 6 1760in1 version use the same board/cpu revision gb2000s and no jamma connectors like mine, if so it s not an h5 (1080p system) but an h2+/h3 (720p) that is still compatible with your revision board too, i think the h5 is the one used on the pandora 3d/key7 version, the one I purchased is a Grogrou pandora 6 720p with “advanced cpu”). I was not able to take a look on the chipset label due to a strange heatsink mounted on the pcb, I m planning to remove it at soon and check.... but from armbian and freedroid report the cpu as a h2+/h3 from allwinner..
I would imagine your board is a H2+, that is what is in mine and akira84s. My board revision is the same as Akira84s, the software on mine though is basically the same as yours (Grogou branded pandora 6) rather than heroes 5. His image and obviously my image both work due to the same hardware. Retrorangepi when in exiting to the command line if i remember right for my board report the same allwinner information that you have previously seen. So i imagine the CPU in your machine, mine and akiras is at least one thing that is the same lol.
The 1760 Arcade box is DEFINITELY a H5 CPU and not a H2+/H3 here is an image of the 1760 board...

Apart from the strange way they have mounted the CPU on that board does the layout look like yours? Its the only other Allwinner arcade games type board i know of with no jamma (apart from the 'home' versions of some of the REAL pandoras).
From what i understand the CPU is very similar to the H2+/H3 both are quad core, it main difference is the shared GPU in a H2+/H3 it uses the Mali-400 MP2 but the H5 GPU uses Mali-450 MP4. Apparantely this very small difference is enough for retrorangepi at least NOT to run on the H5...
http://www.retrorangepi.org/about/ at the bottom of the page it says "NOTE: Until we get working GPU drivers, there will be no support for new boards like Orange Pi PC2, Orange Pi Win, Orange Pi Prime or any other with Mali 450 GPU or A64/H5 CPU." Whether that means it will not boot at all or if it just means retropie side of things will not run but the rest of the linux side (command line, Ambian GUI etc) will i dunno.
nasoftz ha scritto:UPDATE:
if you want to make some experiment, you can install mame4all and some other android emulator on the 3droid image we already tested..... they works!

I m already trying to enable my joystick controller, i was able to manage mame4all using usb external pad... probably your/Akira integrated joysticks will work out of the box.... an alternative way to get an “openpbdroid” version :p
That experiment sounds like fun when i have a bit of free time, for a newbie to linux like me just getting the dd command working was a bit of a nightmare hehe But yeah i do plan of trying other things like Mame
nasoftz ha scritto:For my board revision
I must find a way to compile a remapped “sun8xi_gpio” module and properly install it to get my controller to work on armbian or android, more easy on 3droid or maybe from 1760in1 original image where I may get full system control than on the original heroes5 “locked” system img, I have already tried to simply overwrite it, but the system does recognize that module anymore ..
Hmm this should be possible, on the Linux side of things the source code for sun8xi is available online, also i am not 100% sure but I THINK older versions of retrorangepi may have supported that GPIO. Im sure i read something somewhere about a different kernel revision having that driver.
I found this driver which is for use in Ubuntu/Debian installs on the Orange Pi which Armbian is based on and its named very similar to what you require, could this work???...

Even if you had to start with a plain Debian/Armbian install and then install retropie or similar once you have things going that would be a start at least. I have no idea how or if it would be possible to port anything like that into our heroes5/pandora6 img files though.
