ALE C64 is a Commodore 64 emulator written in C.  This is the oldest version I've seen on the net, so I thought I'd include it here for completeness.

Ale C64 is a Commodore 64 emulator.  This particular version is for DOS.

Requirements: 486/33 (25 FPS) or 486DX2/66 for 100% speed.  Need 4MB RAM.  See detailed description for what's new in this release.
