Unscrew the back of the unit take out the internal sd card pop it into a card reader and write the. img with a free windows program called win32diskimager put it back together and your done

I managed to swap out the 4gb card with a 32gb card on my RS-97 i have made a quick guide below if anyone else want?s to try it as well.

(REPLACE 4GB CARD WITH HIGHER CAPACITY CARD)

Step 1 Download the firmware here https://mega.nz/#!JIBVDaDa!K1IrPbrjHrdiXQOX9w2b-EAB9n7GHFeQkE084R-cBiQ

Step 2 burn the image file to your new micro sd card using this https://sourceforge.net/projects/win32diskimager/

Step 3 Expand the Fat32 file system using this https://www.disk-partition.com/free-partition-manager.html

Step 4 Open your RS-97 carefully and remove the micro sd card then insert the one you just created and close back up.

Step 5 It should boot and use the full storage available on the fat32 file system as you can see in the pics below enjoy ;)

Great job snesfan :D Out of ignorance I wanted to ask, if you port Opendingux to the rs97, will it be the same for the papk3p apart from the lcd and the controls? Is it possible a unified firmware for these machines?
Assuming everything on the board is identical minus just the LCD resolution and inputs, it should be fairly easy to make board files for buildroot. They can share most of the same rootfs. (Think a laptop and desktop can run the same distro of linux, same architecture but different components, same libraries and mostly same binaries) I'm using kernel headers for 4.x kernel so you probably don't want to try and link into it from the 2.6 kernel that comes on the papk3p.

So the kernel will likely need a bit more work to get to run. The kernel will need a branch of the config solely because of the LCD differences, and maybe ram chip(dont know the full extent of the differences) but can share a good majority of code because of its simularities.

The uboot might not need changed as long as you load the kernel to the correct memory address the current uboot is pointing. I will be making a device tree for the 4.x kernel and latest uboot for the rs97, I don't know how a bootloader without a device tree interacts with a kernel that uses one. The books and stuff I'm reading assumes you are doing both with device tree and sharing files between bootloader and kernel source.

I will assist anyone wanting to port what I come up with to the papk3p or any other device once I have something to release on the rs97. I plan on documenting the entire out of box to working OS stack process so it should be simple enough for someone with moderate programming skills and a desire to tinker. (Because that's where I'm at :)  info is just scattered everywhere)

Now this is what I am talking about! A few weeks ago, now going on a month... I asked for growing interest in hopes of a new dingoo... Excellent work guys! Brilliant! I knew the community would benefit from this device!

I also like the different entry points from SNESFAN and Jack83.

SNESFAN willingness to get a recent opendingux support is really usefull and it will help in getting some of the most recent software from the GCW zero available to the RS-97 but I also think getting some kind of local pack with better emulators than the one included by default in a short time will boost interest in the device and I guess Jack83 is  ready for the task.

One of the trouble with the GCW Zero is that it was not widely available, didn't got enough support to have things done in time. mth and ayla (pcerceuil) efforts to have recent kernel seemed useless for a lot of final users that focused on direct functionality and lost interest in the device.

Having quite immediate pack with lot of emulators and software available will help to gain audience (given the relative fair price of the device) but I definitely want to see support for more polished software, unified interface (? la emulationstation or something like LionRSM emus on dingoo a320), as well as more demanding emulators (mame, fba latest builds, ps one).

The  screen resolution should be also usefull for some arcade games or to be able to use filters or scanlines if it doesn't ruin performance. I really hope we could see ipu scaling and hardware filtering as it improved performance greatly on the dingoo a320.

That being said, I'm still waiting a little before buying the device, given I already own GCW Zero, A320 and a GPD XD.

Cool just figured out how to switch between both menus :)

I tried to boot the Emulationstation from the gcw zero build with no go, I unpacked the opk see what files are in there
sometimes there's a .dge file

Fantastic work Jack83
We have have the emulators running at the correct aspect ratio!
It's really letting that screen shine.
Performance is still worse than I remember the A320 being, namely pico and gpsp, but this is an amazing start!

Just a heads up i got my extended battery today test trialing it out see how it performs.I hope it last so far so good thanks to lemmywinks for the link and stuff.

Update tested most the local pack most all work but has the resolution problem where you can only see half the screen.I hope there can be a easy fix for this.

Well i finally got my unit in. Charged it up and played some super mario world and i beat captain commando. Emulation is surprisingly good and i dont notice any input lag, there were a couple instances of frame skipping while i played smw, but nothing jarring.

Battery is about half full after 2 hours of play time which is disappointing, but not unexpected. Buttons feel solid, if a bit rattley, but very responsive. I wish the screen was protected though, makes me nervous about throwing this thing in my pocket knowing that if i bump into something the screen could be damaged.

Seeing the posts about jack83 and snesfans progress is encouraging. Very excited to see where this leads and id be happy to do some testing if tutorials are written for demoing new software

The whole secret to make it run in the correct resolution is the "sdlfix.so" that can be found in the dmenu folder and the emulator folder (they are the same).

You can take a look at apps/DinguxCommander on how its done:
The default executable is "DinguxCommander_.dge". If you start this, you get the resolution problem. I just created a script "DinguxCommander.dge" with the following content:

Code: [Select]
#!/bin/sh
LD_PRELOAD=./sdlfix.so ./DinguxCommander_.dge

Thats all to make it work. You need an editor that can handle linux line ending like notepad++ or similar to save the file. (LF not CRLF). Just copy the DinguxCommander.dge script and edit it, most editors will honor the existing line endings.

This also works for the emulators I added in the zip. There are two requirements:
- The application has to use SDL for drawing to the screen. Most of them do, some don't
- The application has to be running in the first place. If its running and has distorted screen, give this fix a try

Tried this with a few games which run fine on the K3P and also run (albeit stretched) on the RS-97, every one crashes back to the menu. I'm using the code above as a template and altering the .dge file then saving it as *****.dge, file type is all files. I have no idea what CRLF or LF are though, had a quick Google but don't know how they apply to notepad++ files and I know nothing about coding. I'm putting the new .dge and the sdlfix.so file in the same folder as the original .dge

Actually scratch that, just copied an edited DinguxCommander.dge file and renamed it instead of using save as and Doom worked straight away, thanks!

So got CZDoom (not the 1.0 version, that crashes on the RS-97 but works fine on the K3P) and Hugo working, Doom seems to work fine but some of the PCEngine games have garbled graphics. Also no CD audio on the CD games but from that's probably the emulator, seem to remember it did that on the A320 too.

Cave Story runs and you can hear the background music playing but nothing on screen, SuperTux and UMG crash back to the menu.

Just a heads up i got my extended battery today test trialing it out see how it performs.I hope it last so far so good thanks to lemmywinks for the link and stuff.


Hello,  I'm wondering how the battery test went.  How long does the factory default last vs. the new one?

Also.  Is this the battery you bought for the RS-97:

https://www.aliexpress.com/item/High-Capacity-Gold-battery-bateria-BP-4L-BP4L-Mobile-phone-Battery-for-NOKIA-N97-E61i-E63/32833741863.html?spm=a2g0s.13010208.99999999.269.9eqv0f

Is it the same for the PAP KIII Plus?

Thanks in advance!

I don't believe the battery you posted would be compatible with the RS-97, it uses the "Battery: Replaceable BL-5B 890 mh (standard old Nokia phone)." The highest capacity compatible battery I was able to find was this one https://www.ebay.com/itm/New-Replacment-BL-5B-3-7V-1390mAh-Battery-For-Nokia-N90-3230-5300-5070-6121-6080/371779975725?hash=item568fd03a2d:g:fh8AAOSwKfVXDcAc

Ahh.  I see.  Well I found a bunch of 2000 mAh on AliExpress app.

Like this:

I just question the legitimacy of that.  That's over double of the original.  Hmmm
