ColecoVision

The Coleco version is coming along.  I am using the Coleco ADAM as the target for development because it has more memory available.  I believe I may have posted a screenshot of this version previously (somewhere on the internet) however it was before I added all the sprites for bullets to the MSX version.  In porting this over, I broke the Coleco version - it's all to do with sprites and non-maskable interrupts.  The non-maskable interrupts problem is solved at least from a crashing standpoint, but the sprites are still randomly disappearing.  I'm taking a break from this for a few days, but when I come back to it the Coleco ADAM version is done with the exception of sound.  I'll likely try and get memory usage down and see if a proper ColecoVision version is feasible.  At that point, the final Coleco target (ADAM only, or both ADAM and console) will be determined.
