This is my attempt at a Commodore 64 emulator; mainly in order to teach myself how this nice computer worked. It's quite incomplete, but at least the basic character video, keyboard and .d64 disk drive emulation works. No attempt was made at cycle-accurate emulation or anything like that; however, this code should give a nice introduction on how to write a semi-decent emulator without making it too complicated :-)
Everything except the ROM images and the .d64 image are licenses as beer-ware:

Just go to the src directory and run make. The resulting emulator can then be started using ./c64emu. Note that SDL 1.2 is needed to build this.
All the ROM images were obtained from http://www.zimmers.net/anonftp/pub/cbm/firmware/computers/c64/. The C64 diagnostic disk was obtained from http://csdb.dk/release/?id=75835 - these items are provided for convenience only.
