Hello again me on this great project :)
I solved my previous SD problem (i posted my solution), but now i have another problem.
I switched my first test screen from a ILI9341 320x240 to an ILI9488 480x320.
The problem now is that the display_write_frame need to do some maths to crop and scale the original NES resolution to fit the bigger 480x320 and it really slow down the gameplay.
Games that runs at full speed at original resolution, now are unplayable speed scaled.
I've tryed all the four options in the example with no acceptable speed.
Is this a known issue or i'm doing sometings wrong?
This is the code used to initialize the screen driver:
