You simply cannot re-distribute original or patched AmigaOS files, no matter what you write into your readme. Sorry, that's a fact.
I think we should discuss how much work it is to have the patch contain patches and have the installer do the patching, or have Hyperion sanction this effort.
In addition I doubt you can use the name "Boing Bag" and pretend it's official one. It's not.
You mention renaming it. I agree.
Two naming suggestions for your[ie everyone] consideration:
1) Community BB3.
2) Boing Ball 3 (start numbering at 3...)
