{{#seo: |title= (Computer) - GameBrew |title_mode=append |image=coggba2.png |image_alt=CoG }} 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. ==Screenshots== https://dlhb.gamebrew.org/gbahomebrews/coggba3.png https://dlhb.gamebrew.org/gbahomebrews/coggba4.png https://dlhb.gamebrew.org/gbahomebrews/coggba5.png ==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. * Fixed problem with Mode 2 redraws. '''0.9.0''' * Initial release. ==Credits== Thanks to: *Alepus, Dahak, DJammer and Leix for testing CoG so thoroughly. *Guyfawkes and Woo for their continued support. *Matt the Squirrel for support and suggestions. *Sean Young for fairly concise TMS9918a documentation. *Richard F Drushel for his Pitfall! disassembly. *Daniel Bienvenu for the OS7Prime documentation. *The ColecoTech author for making this emulator look awesome in comparison. ==External links== * Author's website - http://www.btinternet.com/~softtec
