Hi, I'm posting my project, provisionally called PS2RP. I am using a box, similar to the Switch, which is a common case to use with a rasperberry. Possibly I use a translator, so I'm sorry for mistakes in writing and grammar.

Specifications:
• 7 "TFT Chinese LCD 800x600 - RTD 2660H Controller. In tests I have identified that the brightness and the viewing angle of this screen is horrible, I will change soon.
• Generic PS2 control
• 2x tablet batteries for use in series ~ 7,4v
• Stereo Sound
• Headphone output
• Freeboot on the memory card
• Games uploaded by Orange Pi Zero Plus
• Cut-out 79xxx GH-061-12 board


Some points have not yet been defined, such as the BMS and the type of connection to the screen.
My option would be VGA, but I could not make the connection yet, even taking the H and V points from the motherboard, the screen did not display. In this case I believe they can help me without the synchrony should not display the image in green at least?


Thank you all for the great work on the guides.

Hi,
first of: your work looks really nice so far!

AFAIK the PS2 only outputs interlaced / 15khz VGA, which is not supported by many displays. I'm not quite sure, but according to the datasheet of the RTD2660H, it should also accept component / YbPbR input. It seems to be the same chips as in the eyoyo screen - so component might be a very good alternative for you!

Looking good, nice trim! As @Nold mentioned only a handful of screens support 15khz VGA signal so that would explain why you are not seeing an image. From memory there is a 5” and 5.6” in 4:3 ratio from good display and I think Nold mentioned that the screen he is using for his build might work.

Something to be aware though is that the good display screens I used didn't play well with my previous PAL PS2 board, the image was flickering a lot. This could be due to native resolution, the PAL (European) PS2 board is outputting 576i vs an NTSC (US,Japan) PS2 board which is does 480i. It's also a good idea to get NTSC games for this reason if you want to use that screen.

Mind you, you could use a PAL board and load NTSC games, in that case the flickering image will only happen when you navigate the menu, if you load a NTSC games the image will be fine.

At least this was the case for the 5.6” good display screens that I tested.

Hello, I am posting my advances in PS2 development.

I replaced the 78M05 regulator with an LM2940 and mounted a 7.4v 20,000Mha battery which was a Pineng Powerbank. This PowerBank has always worked a lot, managing to carry 4 full charges on a Zenfone Max Pro M1.

I faced many difficulties to perform control welds. The PCB quality of this control is very poor, dropping tracks. The result in my opinion is not good, but it works.

In relation to the LCD screen, the one I have had bad average viewing angles. I bought a new IPS in China that showed good results.

I started studying a way to use Ypbpbr, which should be simpler. For now I am using ps2hdmi.

At the same time I started studying the RTD2660 / 2662 firmware to enable the video component and change the Boot Logo. So far I managed to dump the firmware, I believe that next week I have more advances in this point.

It is a case printed for rasperberry pi, but I ended up customizing the case of a lcd with plastic mass.

The problem with the HDMI adapter is that it letterboxes the image. This is something I've had a chip on my shoulder about for a while now, but I've found no way around it. I'd love to hear if anyone else has any suggestions on that!

So my studies and attempts regarding firmware are to enable ypbpr, but the available source codes do not have the menu options currently available on my firmware. And the question of customization of my factory firmware is not possible since there is no way to open it in Keil.

Also the process of writing this firmware is extremely slow.

Speak personally, some updates.
Since the last post, I was not happy, with some features mainly finishing. so I acquired an Ender 3 in the meantime. I continued developing the case based on timee1994.
I printed out some templates for testing and adjustments. Below are some photos.
As the next steps, I will organize the internal part better, the idea is to support all the items trying not to focus on anything loose and to facilitate possible maintenance.
