In their own words
TRX64
TRX64 is a free, open-source Rust runtime for cycle-accurate emulation of the Commodore 64, 1541, and 1581. Its reverse-engineering tools include rewind, byte-exact reverse stepping, write tracking, observers, traces, marks, and sandboxes. A daemon exposes JSON-RPC 2.0 over WebSocket, with project capabilities available through JSON-RPC methods. Users can work with trx64cli, a terminal cockpit with an optional native emulator window, or C64RE, a browser-based reverse-engineering workbench. The daemon supports c64, u64, and 128 machine selections, with PAL and NTSC C64 models documented. Media and hardware support includes D64/G64 disks in 1541 drives, D81 disks in 1581 drives, cartridge types, REU, GeoRAM, and the Ultimate Command Interface. It also supports machine snapshots, reverse-debug buffers, trace logs, and VICE .vsf snapshot conversion. Releases are available for Linux, macOS, and Windows, with builds for x86_64 and arm64 where listed. C64 ROMs, including the 1581 DOS ROM, are not included and must be supplied separately.
