The Game Bub project aims to create an open-source FPGA-based handheld device for retro gaming. This device can emulate classic gaming consoles and allow users to play their physical game cartridges. There is enthusiasm for the idea of open-source hardware, but concerns persist about the availability of components as they go out of production. Users suggest that maintainers could offer updated component lists or even sell component kits to help circumvent these issues. Furthermore, the fear of potential legal challenges from companies like Nintendo regarding IP rights is a major concern for the project. Nevertheless, the community expresses hope and excitement about preserving retro gaming, emphasizing the importance of initiatives that allow access to classic games despite the decline of original hardware.
