What it is
BMC64 is a free, bare-metal Commodore 64 emulator for selected Raspberry Pi boards. Its bundled release also emulates the C128, VIC-20, Plus/4 and PET, including C64 PAL and NTSC variants. It uses VICE, with Plus4Emu available on Raspberry Pi 3 for more accurate Plus/4 emulation. Frames are timed to 50/60 Hz display refresh for smooth scrolling, and the project advertises low input-to-audio/video latency. A reported C64 boot over composite takes 4.1 seconds, with no shutdown sequence required. Wi-Fi and Ethernet support uses such as BBS access and C64 OS networking. Installation involves writing a release ZIP or image to a FAT32 SD card. Required ROM files must come from a legal source, and the minimum C64 ROM set is needed to start. Supported boards are Pi Zero, Zero 2W, Pi 2 and Pi 3; Pi 4 and later are unsupported. An optional local-network web interface manages status and SD-card files and can use a PIN.
