I have the exact same problem, all the hidden files are shown in the menu as well, like ._dstwo and so on. Super frustrating. I have tried deleting these folders using the terminal on my mac, ensuring they don't exist, but they seem to be created...
I went to a garage sell last saturday, and the lady had a PS2 for sale, but she had a sign on it that said "Nintendo -$50", had to laugh, almost bought but she didn't know if worked, and she didn't have controller or cables, so I passed.
