| + | The project resulted in a fully functional handheld console. The system successfully handles real-time input from two controllers without latency. The OLED display provides a clear interface, and the integrated Bot offers a challenging solo experience. The memory optimizations (using the F() macro) ensured the system remains stable during long play sessions. | ||
