LibreCores is your gateway to free and open source digital designs and other components that you can use and re-use in your digital designs. Towards this goal, LibreCores provides you a comprehensive and easy directory of digital design components ("IP Cores"),
means to assess the quality of those components, and documentation to learn more about the use and contribution to free and open source digital designs.
MiSTer is an open project that aims to recreate various classic computers, game consoles and arcade machines, using modern hardware. It allows software and game images to run as they would on original hardware, using peripherals such as mice, keyboards, joysticks and other game controllers.
