Thanks! Since I can dump the PICs electronically I didn't decap them, but I'll have to put the games back together. I should be able to post some vids tonight.
I got the DK JR and pinned out the switch connections. I need to build a rig to figure out the LCD pinout. I'm not sure if it has an SM510 or SM511. I assume SM511 because the piezo is only connected to one pin, but I don't hear a melody while playing the game.
I also got a Radio Shack Think Fast, but it's got a glob, so I'm guessing it'll be an unknown processor like Lights Out has.
And I've got a Quiz Wiz Challenger coming.
