Hi -
As promised, here is an update regarding the Flash support in Etoys. I think the story is that there are *two* relevant packages in the 39a repository: There is a "BalloonMMFlash" package which is fairly close to the Etoys "Balloon-MMFlash" category. Looks like the hyphen got removed to make this a separate package. This is close enough to be a good potential ancestor. There is also a "Flash" package in the repository which I think was the version that I had produced for Croquet.
My suggestion would be to do something a little weird: 1) Adopt the BalloonMMFlash package as ancestor, merge it[*]. 2) Do an underscore replacement. 3) Rename the category to Flash and adopt the Flash package. 3) Merge that [*]. 4) Publish the new version as basis for Etoys.
[*] Merging in this context means to review the diff and to review all changes and ensure that modifications are correct.
This serves the purpose of ensuring all changes that have taken place are in the Etoys version. If you would like me to do that, I can, but I don't know how you'd like to deal with the rename of the package in the process.
Cheers, - Andreas
