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.
