Thanks for the detailed writeup, exorio. For those interested in a closer look at the hardware, it is worth mentioning that Steward has some good teardown pics on his site at https://steward-fu.github.io/website/handheld/ldk/teardown.htm.

Using steward's pictures, I was able to find the lcd panel for this device on panelook: http://www.panelook.com/990001260_Innolux_2.7_LCM_overview_30682.html. They have a datasheet available, which I have attached to this post was going to attach but the system doesn't like it. PM me if you want it and can't get it from Panelook.

It doesn't seem too promising in terms of potential screen upgrades though. YUV interface, 51 pins dual row, nonstandard subpixels, and "discontinued"... I don't know what's going to be out there for compatible panels. I was hoping for something more plain like 40-pin single row TTL RGB666 or RGB565... I've been out of the LCD swap game for a few years now though and I don't read mandarin, so perhaps I'm just out of touch.

Does anyone else have any suggestions or ideas for potential screen swaps for the LDK vertical? I am particularly interested to hear from:

1. The software side - Is it possible to send RGB 565 or something more conventional over the lcd output interface? Is it possible to output at a different output resolution (like true 320 x 240 RGBstripe?)

2. The shenzhen/hardware manufacturer side - Do you have any suggestions for compatible IPS or VA-style panels?

That's the guide I was looking for! I stumbled upon it before, but can't find the link.

Just want to point out this picture :



That dark blob is the viewing window touching the LCD screen. That's one of the annoying defect, apart from the taped silicon pad on the LR button.

Mine has that defect too, in the EXACT same location on the screen.

Using tempered glass greatly reduced this defect.

Clearly every unit have this taped silicon pad too (silicon with thin double tape, placed on the LR button post)

That even look worst than mine.

Hmmm.... I thinkI might have look for an old TV remote and see if the silicon pad is decent enough to cut up...

The problem is not the silicon pad itself. And they're not contact membrane, it's just plain silicon, they're there to add a mm or so height to the button post. Nothing more. The LR buttons are switches, unlike the facebuttons.

So for those that are having huge issues like I was having getting Cannonball to run with the right ROM set. Its needs to be a certain ROM set. That ROM set is B version and it is the upright version only.. Look inside for this file.

"epr-10381b.132 file." This is file you need to check to make sure this will work correctly. Also Cannonball needs the rom folder and those files from the zip file need to be in that folder. If not Cannonball will not work. Hopefully this will help others.  The Vita version instructions seem to work for this version as well when it comes to the right rom set to work. Some one can PM if they need more help with Cannonball.

Any advice on how to get Rise of the Triad and Spear of Destiny to run with full rather than shareware files? I deleted the shareware files and copied in the full files and now neither game will start.

RetroFW version of Wolf3D is a bit iffy

not sure what version would run on it, said to be GT interactive version, but I only have steam version.

Just use useless firmware if you want less headache with the native games. ROTT and Wolf3D (ECWolf) can use the full version files without problems in useless.

besides on my experience, SNES runs better on useless firmware anyway

The developers are here in the forum, and the softwares are provided for free, so I don't want to complain much.

Useless Firmware works fine for me anyway.
