MacOS X 10.6.5, Open fresh Squeak4.2-10548-alpha, update to 10770, open with Cog 4.0.0.

Attempt:

(Installer repository: 'http://www.squeaksource.com/Balloon3D')
        install: 'Balloon3D-All'.

Get the following notification:
This package depends on the following classes:
  InterpreterPlugin
You must resolve these dependencies before you will be able to load these definitions: etc. ....

So then I do the following to resolve the dependency of Balloon3D on InterpreterPlugin":

(Installer repository: 'http://www.squeaksource.com/VMMaker')
        install: 'update'.

Attempt again:

(Installer repository: 'http://www.squeaksource.com/Balloon3D')
        install: 'Balloon3D-All'.

When loading Balloon3D-VRML get 'Error: Digit value initialization failed.

The last version of Balloon3D-All is from 2004. I think you should load
Balloon3D-1.1.2.mcm.

The cause of the error is that Character >> #digitValue now returns -1 for
all byte characters (asciiValue < 256) that doesn't have valid #digitValue.
This was different earlier. The number was negative, but not always -1.
According to the comment the only requirement is to return a negative
number.
There's another case when you'll get an error. The characters between $a
and $z now also have valid #digitValues, but the VRMLStream class >>
#initialize doesn't expect that.

Ok, I see that Balloon3D-1.1.2.mcm is better than Balloon3D-All.
Balloon3D-1.1.2.mcm doesn't load all the packages in the Balloon3D repository.
It leaves out:
Balloon3D-Packaging
Balloon3D-Plugins
Balloon3D-Pooh
Graphics-External
Graphics-Tools
