Memory heatmap from GT1 files

Post by marcelk » 08 Oct 2019, 16:16

While solving GitHub issue #41, and in figuring out where in RAM to put the SDC/MMC file loader, we got interested to learn where existing GT1 files tend to load. Answering this is not too hard when combining gt1dump.py, awk and gnuplot. The result is the heatmap attached.

We can see nobody loads in page 1, or at the beginning and the end of the zero-page. Also the screen area where Loader runs is untouched, except for the "patch" inserted by the GCL compiler.
