Installation instructions

OR

Alternatively create another location for your tools and modify settings.json to reflect where they are.

Press F5 to compile and run if you have set up the KickAssembler extension. Otherwise run build.bat on Windows or osx-build.sh on Mac (both assume /tools/ folder is set up)

Folder structure:

bin/         Binary output folder (not part of repo, but build will create main.prg here)
lib/         Library asm files
res/         Resources like charsets and sprites
design/      Design of charsets and sprites
docs/        Some helping documents for coding
examples/    A couple of 6502 code examples
assignments/ Solutions to the 4 assignments including full game
tools/       The folder you place your tools in to use the build scripts
   
main.asm     The actual game code but with 4 empty functions as assignments
