I finally got around to opening it up recently, and here's what I found


Does that look at all normal? I mean, I don't see any ROM chips at all, so that would explain why it isn't working. Has anyone seen anything like this before or recognize where this might have come from?
I might message the seller to see if he'll replace it, but it's been like 6 months so I definitely wouldn't blame him if he doesn't want to. Good thing it's a cheap game...
