Is it possible for a cartridge to mess up a motherboard?

I had to buy a new mobo for my 2-slot Neo after I installed an official, legit cart (Bust-A-Move Again) for the first time. The graphics glitched on every cart after that. At first, it was just that one slot, then both. Will it be safe to run this cart on the new board? Just a coincidence?
 
I've never seen a cart that would mess up a motherboard... Theoretically it's possible if the logic gate interfacing that specific pin shorted to ground.

Generally what happens is there's some crap on the cartridge contacts and it makes the slot dirty. Clean both VERY well.

Theoretically, I was speaking of the cart being bad... and damaging the board.

In all the board repairs I've done, I've never seen a cart that would damage a board... Even when plugged in backwards.
 
Have you cleared the back-up ram? If you get screwy stuff in there, then you can easily not be able to do anything else. Also, have you replaced the battery? If that starts to go, perhaps the backup ram got corrupted.
 
Backup RAM corruption won't cause lines on the screen.
