C.o.G is a Colecovision emulator written by TheHiVE. This emulator features superb compatibility, with sound, and configurable controls.
The emulator also comes with an easy-to-use injector. However, as the emulator has no menu system, you have to create one binary per game. Although inconvenient, the up-side of this is that Colecovision games are small, so each binary tends to be under 100k.

Changelog
0.9.7
- Reorganized VRAM and VDP rendering functions.
- Rewrote and optimized VDP register handler.
- Changes to injection process, to provide support for Pogoshell. Known ROMs are listed in binary and identified by CRC.
0.9.6'"
- Fixed VDP BL - No more mode switch glitches - video builds 'silently'.
