c64js has no write-up on Specifiction yet; its figures are above.

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.
