Retrogaming console with raspberry Pico and Circuitpython - 1 - first test

I am currently designing a retrogaming mini-console project for my students at the IUT in Rennes.
I'm using a raspberry pico programmed with Circuitpython with a ST7735 160x128 LCD screen.
I was hoping to use the pico for mp3 decoding (external SD card), but I was losing animation fluidity. So I use a dedicated module (DFPlayer mini).
For the moment, these are only simple tests for a loading screen, a title screen and a game selection screen.
