Skool Disassemblies

SkoolKit includes source skool and ref files for complete disassemblies of Skool Daze and Back to Skool. To create the HTML versions of these disassemblies, open a terminal window, change to directory where SkoolKit was unpacked, and enter this command:

$ skool2html.py sd.ref bts.ref

A few seconds later (or minutes, depending on the speed of your machine), the HTML versions of the Skool Daze and Back to Skool disassemblies will be ready in the skool_daze and back_to_skool subdirectories (which will have been created if they didn’t already exist).
