In addition, thanks to a document contained in the project, it is possible in dual-boot to place the fastest (bare-metal) Commodore 64/128/PET emulator BMC64, thus building an interesting retro package on a single SD card. Installation requires running a single script on a clean Raspberry Pi OS (full) Legacy and waiting about two hours for the packages to compile and install. This lets emulators use full power of Raspberry Pi, making them more stable and useful in combination with additional retro-software. All this without the X.org manager, only a multimedia SDL2 library and from the CLI / Raspberry Pi OS (Legacy).
MacintoshPi is a small project that allows running full-screen versions of Apple's Mac OS 7, Mac OS 8 and Mac OS 9 with sound, active Internet connection and modem emulation under Raspberry Pi.
