| License | The project is licensed under GPL-3.0-or-later. | The project is licensed under GNU GPL version 2.0 or later. |
| Purpose | TRX64 is a cycle-accurate Commodore 64, 1541, and 1581 emulation runtime written in Rust. | ViceSharp is a C# port of VICE, the Versatile Commodore Emulator, targeting .NET 10. |
| ROM requirement | C64 ROMs are not included and must be supplied in ~/.trx64/roms or selected with --rom-dir; the 1581 DOS ROM is also not included. | ViceSharp does not include Commodore ROM images, so users need ROM assets from an installed VICE package or another legal source. |
| Support | The maker directs users to GitHub issues and says they cannot provide real support. | The repository directs users to file regressions in its GitHub issues and asks them to include the commit SHA, .NET SDK version, invocation, and reproduction details. |
| Supported machines | The daemon supports c64, u64, and 128 machine selections, with PAL and NTSC C64 models also documented. | The repository describes working C64 emulation and a VIC-20 core, while C128, PET, and Plus/4 are listed as not yet supported. |

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.
