XRoar
XRoar is an open-source emulator specialized in the Dragon 32/64 and Tandy CoCo (Color Computer 1, 2, and 3) microcomputers, as well as the Tandy MC-10. It accurately reproduces these 8-bit architectures, including advanced features like debugging via GDB or floppy disk management.
On macOS, it supports recent versions (from 10.13 onwards), with dedicated builds for x86_64 architectures. No official version for Apple Silicon or older macOS versions (such as PPC builds for 10.4) is mentioned in recent sources. The emulator requires ROM images to function properly, available through dedicated archives. The license is GNU GPL v3.
