Homework registration and FC game console combined

Project Introduction
This project is based on the ESP32-S3 development board and features homework registration and FC game playback.
1. Homework registration is my own idea. The UI is designed using the LVGL library.
In the digital age, mobile phones have become an indispensable tool for children to complete their homework. Prolonged mobile phone use not only affects eyesight but can also distract children. Therefore, I wanted to create a homework registration toy to help children manage their homework efficiently and cultivate good study habits.
2. The FC game is the open-source Retro-Go. To deeply recreate the gaming experience of childhood, a separate design was adopted for the screen and development board.
3. Learning and gaming use two sets of code. With sufficient resources, two SP32-S3 development boards and two SD cards can be used to recreate the fun of inserting cartridges.
Project Functionality
This design is based on the ESP32-S3 development board; it has multiple buttons for FC games, an ST7789 screen to display homework completion status and FC game visuals, an SD card to store homework registration prompts, English listening and reading recordings, and FC game playback, and a speaker amplifier for sound playback.
When using homework registration, it can be controlled simply by using the dial buttons on the right side.
When parents are nearby, the ESP32 has offline voice wake-up and command recognition functions. You can use [https://oshwhub.com/lililip/bluetooth-speaker-network-radio-] which has a microphone. Voice wake-up and commands are sent via ESP-NOW to the control interface. Point the command
directly at the microphone, for example: "Hi, Lexin" + "Chinese," "Hi, Lexin" + "Open screen," etc.
Project parameters

: This design uses the ESP32-S3 development board as the main controller;
this design uses an ST7789 240*320 LCD display to show whether homework is completed and the screen content of FC games;
this design uses an SD card for storage;
this design uses an NS4168 as the amplifier for sound playback;
the homework completion interface displays whether Chinese, Math, and English are completed. The Chinese interface has a sub-interface image displaying the Chinese homework requirements. The English interface has a sub-interface for playing listening and reading recordings; the
homework registration program, power-on timer, and pressing KEY A can enter the interface to view the homework.
The FC game interface is based on games I played as a child.

The hardware explanation is as follows:
Due to the development board design, the circuit is very simple.
The SD card circuit
uses SPI communication, with pull-up resistors on each line.
The power amplifier circuit
uses I2S communication.
A pull-up resistor on the CTRL pin keeps the sound output always on.
The prompt sound is based on C3 Practical Guide's Baidu Text-to-Speech tutorial:

The debugging interface is shown in the image. The mobile network is configured using the ESP-TOUCH software
downloaded from the Espressif website . The assignment registration is in the project attachment source code. The FC game is an uploaded .bin file . If you have any questions, please leave a comment. Notes: This section can be used to highlight key points or common mistakes during design and development. Example: The development board's power strip should be plugged into the back; check the silkscreen on the board. Pay attention to the board's orientation to avoid unpredictable problems. The development board can be powered via USB or battery. The battery interface is connected to the 5V port on the development board; a 3.7V lithium battery may need to be boosted to 5V. To recreate the gaming experience of childhood, the screen and main controller are connected separately using a ribbon cable. Images of the completed product can be included here: Figure 1: Game Interface; Figure 2: Assignment Log; Figure 3: Back of the Development Board.
