This is so simple I couldn't believe it myself:)
And if it weren't for Rayman's work and Chip's loader, I would never have seen it!!
Thanks guys.
the test object is the compiled version of this
the loader expects a byte containing the cog number, then three bytes representing the byte count ... and then the raw output of the obj file. I don't stop the cog first... so if you want you can get all of the empty cogs blinking by repeatedly loading the same file.
Makes me happier than.... you know:)
