In their own words
Hoxs64
Hoxs64 is a free Commodore 64 emulator for Microsoft Windows, written by David Horrocks. Its documentation describes cycle-exact emulation and pixel-exact VIC emulation of a C64C, without emulating the grey dot bug. A simulated 1541 floppy drive supports reading and writing, while the tape player is read-only. The emulator handles D64, G64, P64, FDI, TAP, PRG, P00, T64, and CRT files, and includes state saving, a debugger, full-screen mode, and configurable keyboard and joystick controls. Cartridge support covers Action Reply, Easy Flash, Ocean, Magic Desk, and Commodore REU 1750 options in 512K or 16MB configurations. Multiple cartridges are unsupported, and mounting one disables the REU option. Listed downloads are 32-bit and 64-bit version 1.1.2.9. Requirements include Windows 10 or 11, DirectX 11.1, the Microsoft Visual C++ 2022 runtime, 4 GB RAM, and a DirectX 11 graphics card with pixel shader 4.0. Installation requires the runtime and copying ZIP contents into one directory.
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.
