[Wow, didn't know DP had a tech forum...duh! Moved this from the classic forum to here]
My Vectrex is a bit flaky when dealing with a 2nd controller plugged in (to the left port).
I have 2 controllers & have tried swapping them & get the same behavior, so I know that the problem lies in the Vectrex itself, not the controllers.
Problem #1: using a controller test program, I see clearly that the Vec thinks that player 2's 3rd button is always held down. When I press P2's 3rd button (or 2nd button), the Vec thinks that the button is released. Weird. Indeed, 2-player games like Armor...Attack & Rip Off are zany to play when player 2 is moving nonstop *except* when he hits the "thrust" button...
Problem #2: When I launch a game from an original cart or from a multicart, the selection screen is often unresponsive--hitting buttons on P1's controller won't start the game or change the game # or # of players for half a minute or so, then it will respond. Sometimes it behaves better. This almost suggests a crcked solder joint somewhere in the Vec controller plug or PCB somewhere, since it's intermittent.
Anybody seen these problems? Any Vec repair experts out there? Any suggestions?
Thanks,
