You probably mean this?
3rd party solutions like osakit that use some kind of insecure activex trickery are no real alternative though.
Maybe it's not secure (and that's probably one of the reasons why Chrome disabled NPAPI plugin). But I can tell you this
I'm no expert in OSA Kit either, but I know that several users have used it for games on their websites - maybe someone else can help here?
If not, we'll put up some Gamestudio demo using the OSA Kit, which we intended anyway in the next time.

I suppose it's possable it may help you with your quest...

Recently I came across 'GameMaker Studio', and I've found out that it's scripting looks very familiar to old c-script, here is an example:
