Technical notes

Alias for the VICE x64 core. x64sdl is an alternate build name referencing the SDL-based VICE x64 Commodore 64 emulator. In the libretro ecosystem this maps to the same vice_x64 core binary.

See vice.yml for full ROM and BIOS details. All standard ROMs are embedded in the core binary.

No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
