I don't think anyone gets it. The game ports are supposed to be the same.
Same signals on all IIe, IIc, and IIgs.

The _software_ might use it differently, but I _do_not_care_ about what
the software thinks. I'm making my own software, and I can make it think
any way I want. A PDL() value is a heck of a lot easier and quicker to
adapt for something in an Applesoft program.

Is there a way to double the sync on the IIgs? Would that also need some
oversampling of the RGB signals?
