Could you build this?

Partial Basic Arduino code and screen drivers can be vibe coded, but writing smooth sprite rendering, DMA-based display updates, transparent PNG decoding, and SD card file I/O within tight ESP32 microcontroller memory constraints requires real embedded systems skills.

What it would actually take: The firmware requires ESP-IDF or optimized Arduino core leveraging the ESP32-S3's hardware SPI/QSPI with double-buffered DMA to stream frames to the ST7789 display controller without flickering. It also requires an efficient PNG decoder (such as PNGdec or lodepng) tailored for microcontrollers that streams scanlines directly to display buffers or PSRAM without running out of internal SRAM.
