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'.
  • Fixed NMI - Interrupt should only be generated when the interrupt line changes from low to high. This fixes Pitfall! and other assorted ROMs.
    • Note: This is contrary to Sean Young's TMS9918a documentation.
  • Modification to injector so that multiple binaries can be created simultaneously.

0.9.5

  • Found and fixed massive error in Pogoshell plugin code.
    • Note - this is still incomplete, and buggy.
  • Enabled collision detection code (via injector).
  • Optimized IN port code.
  • Preliminary OUT port optimizations.
  • Fixed tiny bug in VDP status register.

0.9.4

  • Fixed memory corruption problem.
  • Fixed problems with various ROMs, including Galaxian.
  • Fixed speed problem in Pitfall II, Dig Dug, Jungle Hunt, and others.
  • Fixed tiny bug in input handler.
  • Added customizable input handler.
  • Enabled frame synchronisation.

0.9.3

  • Internal debugging tool enhancements.

0.9.2

  • Fixed problem with VDP register 4.
  • Added double size sprite capabilities to VDP emulation.
  • Disabled frame synchronisaion (for now).
  • Started to add menu support.
  • Enabled input customization module (not yet fully supported in injector though).
  • Added SN76489A audio emulation.

0.9.1

  • Enabled frame synchronisation.
  • Fixed problem with VDP register 3.
