ColecoDS is an emulator for all things Colecovision and ADAM for your DS/DSi/XL/LL:  https://github.com/wavemotion-dave/ColecoDS

 

Just put out the 9.1 release (the first ColecoDS release of 2024) which adds a real Konami SCC driver for improved sound on the MSX1 games that take advantage of that powerful audio chip.

 

Everything is polished - the Colecovision and ADAM compatibility is very high with just about every game and program playing perfectly. Most of the 'cousin' systems (MSX1, PV-2000, Sord M5, SG-1000, MTX, Tatung Einstein and SVI) are similarly running very close to perfect. I've also added custom overlays for the two new Team Pixelboy games released at Christmas (Space Shuttle and Utopia).

 

I'm well over 300 hours on this emulator.. massive thanks to @alekmaul for the original port and to everyone that has provided feedback, suggestions and help along the way.

ColecoDS v9.2 is released.
 
This version brings in a new (proper!) AY sound chip driver to make all of the latest SGM homebrews plus MSX1, Tatung Einstein and SVI games sound their best. My old driver was a "Fake AY" which just turned the AY sound chip writes into equivalent SN (Colecovision) chip writes. But that was never adequate - the AY has a wider dynamic range, full Envelope support for cool and funky sound generation and more robust noise handling. Some programmers didn't utilize the full capabilities of the AY and for that, my old "Fake AY" driver was fine... but for the best sounding games, with a true AY driver, we now get the full range of dynamic sounds of this awesome chip!
