3.5" TFT LCD SHIELD FOR MEGA2560 not working in 8/16 bit parallel mode

Hello! Here's the display:

It works great with Arduino Mega 2560 and UTFT library:

But I can't get this display to work with the RP2040. I need it to work in 8 bit mode. Performance is not as important as the number of pins on the Pico. I thought the display was designed to work in 16 bit mode, I tried it but that doesn't work either. I also didn't change any pins in the configurations, but it still doesn't work.

Display: 3.5" TFT LCD for Mega 2560 ILI9486

Actually, I'm trying to make a project in which there are 2 memory cards on two separate SPI buses, so using an SPI display is not acceptable for me :(

It is a 16 bit parallel display and will not work in 8 bit mode.

Use setup 105 or 106 and change just the display driver.

It also not working in 16 bit parallel mode for me. But I think that a problem in frequency, may be... Else, I don't know, why it is not working.
