After ignoring my Intellivision for essentially forever, I decided to check out some games I traded for a while ago (specifically, an Intellivoice and Lock 'N' Chase in an effort to see which version I have). The problem is, after vigorously cleaning out the games and the Intellivoice, this is how things look, with or without the Intellivoice (see the attachments). I'm guessing something is up with the system's cartridge contacts since it's across all games with or without the Intellivoice. Is my suspicion correct, and how can I fix it?
