ColEm is a portable emulator of the old ColecoVision videogame console. It should run most ColecoVision games and supports Coleco's SuperAction controllers with spin wheels.

Starting with version 5.0, ColEm has complete Coleco Adam emulation, with keyboard, disk, and tape drives. Both .DSK and .DDP file types are now supported. There are multiple new menu and command line options for working with disks and tapes.
