6502 Assembly Language #7: Debugging and Future Plans

I finally finished the next entry in my 6502 Assembly Language series yesterday, and it took overnight to process and publish. In this one I debug the print-a-number code from #6, and then talk a bit about what to do next. I think I’m going to write a version of Conway’s Game of Life, as a way to develop an operating system kernel along the way. A game will need basic functions like “print a character at coordinates x,y”, so I think that’ll be an interesting way to do it. The game will provide something to see on screen, and the kernel functions will show how to interact with hardware registers.
