I though this was already discussed here...? Anyway, the hardware would
be trivial for joysticks-only, more difficult but definitely doable for
the entire port protocol. I'll try to dig my 2600 specs out of storage
and estimate the cost for parts.

I think this is good, but only if the multi-ports are fully implemented.
There should also be a switch to choose multi vs. regular operation, so
that one could switch between Raiders of the Lost Ark and Combat 2000
(16 players) without having to rewire their system.
