Change 3.5" HDMI display boot logo
Change 3.5" HDMI display boot logo
I am using the 3.5" HDMI display from KeDei for my Game Boy Zeros. It has always annoyed me that it boots with a blue screen and the manufacturer's logo:
The board contains a Realtek RTD2662 display controller. I found some firmwares and source code for this controller on the net and figured out how the boot logo is encoded within the firmware. The firmware is stored on an SPI flash chip on the board which can be programmed externally through the I2C pins of the HDMI connector. I wrote an Arduino sketch and a Windows tool (should also work with Mono on Linux/Mac) to modify the firmware and embed your own custom logo. The logo is limited to two colors and 204x72 pixels. You can also disable the "HDMI" pop-up message or change it's text.
This is how I changed it:
You can find the project source code and more info on Github: https://github.com/floppes/RTD266xFlash
I hope this is useful for others as well

Re: Change 3.5" HDMI display boot logo
Is the type (SKYxxx...) listed on the Github site?
A few days ago I had a panel from 2018 with the number SKY035S13E-180. It is not yet supported, but I am working on it and will update the project site.

Re: Change 3.5" HDMI display boot logo
I have updated the project and included the new display type. Connection problem detection has been improved as well. The GUI will now tell you what went wrong with the connection.
