BMC64 review
A focused, low-latency C64 emulator for Raspberry Pi retro-computing setups.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
BMC64 is an open-source, bare-metal Commodore 64 emulator for Raspberry Pi hardware. It runs directly without a Linux distribution and is aimed at retro-computing setups that use physical controls, original-style displays or compact dedicated systems. Alongside C64 PAL and NTSC configurations, it provides additional VIC-20, Commodore 128, Plus/4 and PET machine configurations. Its supported Raspberry Pi models are Zero, Zero 2W, Pi 2 and Pi 3, making hardware selection an important part of the buying decision.
The strongest case for BMC64 is its focus on timing and physical interaction. The published feature set includes 50/60 Hz video timing, smooth scrolling, low-latency input, and audio/video synchronization. USB plug-and-play devices can be used alongside GPIO-connected real keyboards, joysticks and controls. Storage support covers SD cards and USB drives for disks, tapes and cartridges, with listed formats including .D1M, .D2M, .D4M, .DHD, .D64 and .PRG. Optional CRT shaders and integer scaling support a more period-oriented display setup, while Wi-Fi and Ethernet networking add connectivity.
BMC64 also includes a web UI for configuration, which gives the hardware-focused project a more accessible control layer. Its open-source model and free plan suit builders who want a dedicated Raspberry Pi appliance rather than a general-purpose desktop application. However, the platform choice is narrow: users need one of the supported Raspberry Pi models, and required ROM files must be supplied separately. Choose BMC64 for a Raspberry Pi-based C64 installation with GPIO, storage and display-control options. Choose another emulator when broad desktop platform support is the priority.
BMC64 pros and cons
- Where it wins
- Smooth 50/60 Hz timing with low-latency input and synchronized audio/video
- GPIO, USB, SD-card and USB-drive support suit physical retro setups
- Also supports VIC-20, C128, Plus/4 and PET machine configurations
- Where it doesn't
- Support is limited to Raspberry Pi Zero, Zero 2W, Pi 2 and Pi 3
- Required ROM files must be supplied separately
- Hardware-specific design is less suited to conventional desktop use
