Wow, nine out of ten answers correct!
I thought number 3 might be difficult because it's taken from the intro. Same goes for number 8, even more so, you get to see it for less than a second. But I was actually counting on Fantasy for that one.
Number one is still open. Sorry, idris. It's without doubt the hardest of the lot, very obscure nowadays. Japanese game. Anyone?
EDIT: Oops! Number 8 is still open as well, cause Fantasy got it wrong. My mistake.
