I was thinking the same thing. I want Space Invaders on this thing too. Just haven't had a second to look up controller switching.
Boy, I sure wish SCOTT was here with one of his crazy "it's so simple, why didn't I think of that" ideas/solutions.......
Since you rubbed the magic lamp, your wish shall be granted.
First step is to define the problem: Switching between two plug-and-play games.
AFAIK, you will need to switch the following:
* Joystick, 2 buttons, and ground (7 contacts)
* Operating voltage and ground (2 contacts) -- assuming that power ground and button ground are separate
* Composite video signal (1 or 2 contacts)
* Sound? (might be able to just use a Y-connector, otherwise 1 or 2 contacts)
This leads to several possibilities to consider:
1.) A
manual PS/2 KVM switch with modified input/output wiring adapters i.e. video switching on one of the 15-pin video lines (R, G, or B) and other wires used for the other lines. Not 100% certain if there are enough wires for this, but there probably are.
2.) An old parallel port (printer) A-B switch. (Not sure if it will handle the bandwidth of the video signal.
)
