In their own words
Power64
Power64 emulates the Commodore 64 for running C64 software on an Apple Macintosh. It models the MOS 6510 processor, including illegal opcodes, and provides cycle-precise VIC video features and SID sound with a reSID interface. Drive emulation covers 1541, 1571, and 1581 systems, alongside disk and tape images including D64, X64, G41, D71, D81, T64, TAP, and Lynx. Macintosh access supports C64 and P00 files. Input options include USB or mapped keyboard joysticks, mouse, paddles, and lightpen. Users can mount disks by drag and drop, copy files among disks, tapes, and the Mac hard disk, use the built-in monitor/debugger, and run multiple C64 instances. Version 4.9.5 targets PowerPC and runs on Intel Macs only through Rosetta; it does not work on OS X 10.7. The unregistered version allows ten-minute sessions. Registration costs $32, paid once.
