Thanks for this, RobertaME.🙂 Skimming through it, I can see that it is well written and well illustrated. Not sure if I will ever get proficient enough to do HEX editing, but who knows. I always thought it would be great if we could add more than three balloons to jdrowlands Make Your Own Balloons set. I tried once; never could get the extra balloons to show up in the game.🙃 I notice that you haven't gotten to the CSO part of the tutorial yet, so perhaps, when/if you get to that part it will help me solve the extra balloons problem.
