Hello.

1) Is there any rom like "neogeo" which is needed to run other roms? I'm asking because there are some games which print a message on screen (before starting) that something is missing and they might not work properly - can't remember the exact words... - but they always run for me anyway, so I was wondering why that's happening and if there something to fix or not.

2) When I have a game with the "normal" rom and the "bootleg" one, which one should I use? What's the meaning of bootleg? Are they clones?

3) Am I running out of space already? I read it's safe to use about 500MB for user files...


4) Final request :-) There's a game I liked very much but I cannot remember how it's called.
On screen there's a square board with an image of a girl (undressed IIRC) alternating to an image of some other character, but they're not clearly visible. You are a bug which moves on the square's border and have to clear zones inside the board, trying to cover 80/90% of it. In the meanwhile there are spiders inside the board which try to get you. If you're successful, the girl's pic will be shown. What game is that?

Thanks!
