In their own words
Breadbin466
Breadbin466 is a free Commodore 64 emulator written in Rust, focused on modeling one PAL Assy 250466 machine. Its cycle-driven emulation covers the MOS 6510 CPU and VIC-II video timing and generation, including bus arbitration. The SID sound model draws on a physical datecode 2286 chip and models oscillator, DAC, mixing, and filter behavior. Its Commodore 1541 drive emulation includes a separate CPU, VIAs, mechanics, GCR read channel, IEC communication, fastloaders, and protected-disk behavior. Other modeled hardware includes CIA interfaces, a 1351 proportional mouse, a Datassette with TAP playback and recording, cartridges, and a 512 KB REU. It supports D64, G64, NIB, NBZ, and D7Z disk images, with tools for image creation, conversion, and space reclamation. The integrated debugger provides breakpoints, disassembly, history, and configurable tracing. Native menus and Inspector windows are provided on macOS, Windows, and Linux. Version 0.99.0 is described as feature-complete, with broader testing still remaining before 1.0.
