I have a partially working life game that works on a 32x16 grid that uses only 128 bytes. I still have some bugs to work out and I won't be working on it anymore until Fall since I have my PhD preliminary exams in August but it is certainly possible to optimize and probably squeeze in 32x20 or more. The trick is in the updating routine. I don't recall all the details, but I think my routine used 64 bytes to hold the grid and only used 3 or so to do the update. I recall being under 100 bytes completely, but I could be wrong. But I agree with Glenn that if you are going to work in the SuperCharger environment, you should probably make the most of the extra RAM. I wanted to see what I could do with 128 bytes if I tried, so that is how mine ended up. matt =========================================================================== ||| John V.
