I needed a break from other coding. Therefore, when @ZeroPage Homebrew announced that they would play INV+ (and show a demo named INV3), I remembered an old Space Invaders demo which I had done in 2001 and 2003. Using the RESP trick, I was able to display 11 invaders per row, like the arcade game. So I went back to the demo and decided as an intermediate project I might make a nice little (4K) game out of it. Over the past days I have completed the overall display kernel. This gives a good impression about the final game. It even has basic gameplay as you can shot the invaders. However there are still some major things missing, e.g. the invader bombs, the shield handling and all sound. I based the graphics on the arcade version and adapted them to the different screen layout. They are not perfect, but for now they should do. For the colors I decided go for a medium arcade variant (early versions had no colors, later versions were very colorful). The obvious differences to the arcade are: - The invader formation is much wider than in the arcade, this is a hardware limitation - There are 3 instead of 4 shields, because I can do only 3 large shields (if anyone has an idea for 4 large screens, please let me know) or 4 small shields (like in Atari's Space Invaders game). IMO the larger shields are closer to the arcade. What are your thoughts here? BTW: "Space Invaders Arcade" is only the project name until I come up with something better.
