ts-emu-c64 vs VICE

ts-emu-c64 has no write-up on Specifiction yet; its figures are above.

VICE runs programs made for classic Commodore 8-bit computers by emulating eight systems: C64, C64DTV, C128, VIC20, PET, PLUS4, SCPU64 and CBM-II. It aims for cycle-accurate operation, with 6502/6510 emulation covering documented and undocumented opcodes and precise timing. For C64 software, its emulators reproduce VIC-II video and SID sound, including synchronization, ring modulation and filters. Disk support covers up to four external drives, using disk images, filesystem directories or compatible real devices; joystick input can come from a keyboard or a host-connected joystick. VICE is available on Android, Linux, macOS and Windows, and is free software under GNU GPL version 2 or later. The download page lists Windows builds and macOS builds for Apple Silicon and Intel Macs; the latter require macOS 12.0 or later. Android binaries are listed separately. The manual warns that six systems—the C64DTV, C128, PET, PLUS4, SCPU64 and CBM-II—remain under construction and may be less capable than the C64 or VIC20 emulators.
