It is described so that it can be realized if you purchase the necessary equipment and follow the procedure manual. Since it uses the actual GameCube instead of an emulator, it requires not only software knowledge but also electronic engineering skills. By reading this book, you will be able to gain a wide variety of knowledge, mainly electrical work using Arduino. The Arduino code is published in the book, and you can also download a tool that connects the PC and Arduino. This book does not introduce the detailed implementation of the tools created in Unity, but the technology necessary for implementation is loosely introduced. Whether or not it can be executed at a practical level largely depends on the Internet environment, so we recommend that you purchase after viewing the alert page.
