Replica of the game console based on the Liangshan School of Lishuang.

 
This article details an open-source handheld game console project that combines classic NES games with modern technology. This device not only supports numerous classic NES games, such as Super Mario, Contra, Teenage Mutant Ninja Turtles, and Battle City, but also achieves Bluetooth remote control and wired controller compatibility through technological innovation, providing users with a richer control experience. Original project address: [LCSC Development Board] Smart NES Game Console - LCSC EDA Open Source Hardware Platform (oshwhub.com)
**I. Main Features**
1. **NES Game Compatibility**: This project uses an SD card to read NES game ROMs, enabling access to a vast library of games. 2. **Wireless Control**: The device has a built-in Bluetooth module, allowing wireless remote control via a Bluetooth controller or mobile phone.
**II. Schematic Explanation**
- During the design process, we significantly optimized the pin assignments of the original LCSC official game console expansion board to accommodate the newly added functional modules. - The dual joystick and multi-button design fully considers player operating habits, enhancing the feel and comfort during gameplay. - Added Bluetooth and gamepad module interfaces to ensure seamless switching between wireless and wired control. - Adopted LCSC's official 5V charging and discharging integrated module solution, integrating it into the game console expansion board for integrated high-efficiency power management.
**III. PCB Design Description**
- The PCB layout follows mobile phone design principles, placing the Type-C interface and headphone jack at the bottom for ergonomic design and ease of use.
**IV. Key Program Description**
- The screen's SPI driver has been adjusted from SPI4 to SPI3, with corresponding parameter settings modified in core files such as LCD.c, SPI.c, and nes_ppu.c.
**V. Physical Demonstration**
This NES handheld game console boasts a unique appearance with exquisite 3D-printed shell craftsmanship, exuding a strong sense of technological aesthetics. When connected to the gamepad and Bluetooth module, the overall form is complete and unified, showcasing the charm of the fusion of traditional and modern technology.
In summary, this is an open-source project that combines nostalgia and technological innovation. We welcome enthusiasts to participate in discussions and jointly promote the improvement and development of the project. We hope more developers will build upon this foundation to further enrich its functionality, allowing more people to experience the fun of classic NES games and the convenient control experience brought by modern technology.  
Additionally, please be careful not to bridging the solder joints when soldering the LCD screen. It is recommended to use a small amount of solder paste for soldering, and be careful not to burn the screen.
 
When soldering the battery, note that the left side is ground and the right side is power, so the battery needs to be inserted backwards. If you purchased a 1.2mm connector battery, you will need to cut it and resolder it yourself.
 
Also, the ground and 3.3V of the vibration module are easily shorted together, so please be extremely careful!
